/* Introduction */
By the Informatik staff
Welcome to Issue number 3 of Informatik Journal. It's been a
whopping 3 months since we released our last issue, but at least our time
table matches that of 2600. Sorry this took so long, but guess what. . .
we had a hell of a time getting submissions AGAIN. How about putting your
creative talents to use and writing some articles so we can release
Informatik a bit more frequently.
For our new readers, Informatik is an electronic journal containing
information that is for one reason or another usually withheld from the
public. Sometimes it is for "security" reasons, and other times it is simply
because it is felt that the public does not need to know. Hogwash we say!
Information is power! Have they something to hide? Are there things in this
world that we *gasp* just should not know about? I do not think so.
In other news, we have decided to reduce our news coverage to
strictly hack/phreak/fraud type events. No more general computer industry,
telecommunications news. Our friends at Phrack have that angle covered
admirably, and there's no reason to waste hard drive space with 60-70k per
issue of duplicate news items.
This issue brings us information on public telephone abuse by Brian
Oblivion. Could this be the end of red boxing? For you radio phreaks we have
the tools needed to track down those airphone transmissions, and information
on how law enforcement monitors suspects and how you can get in on the action.
Black Manta provides us with schematics on how you can build a simple universal
garage door opener. HiBias brings us a guide to TRW business reports that
explains just exactly what all those numbers mean, and another article
reveals the workings of those nifty credit card verification machines.
Tid-Bytes is back with some interesting blurbs, and the Hot Flashes of course
keeps you abreast on all sorts of goings on.
We'd like to thank you for your continued readership of Informatik,
and we'd love it if you recommended it to your friends and upload it to
your favorite boards, ftp sites, etc. Remember, subscriptions, submissions,
questions, or suggestions and comments can be sent to our Internet address:
inform@doc.cc.utexas.edu
That's all for now, see you next issue. . .

Introduction
- ------------
Public Telephones: we all know them, and how vulnerable they are
to fraudulent abuse. Well, so does Bellcore and NYNEX and they
have come up with a few methods on combatting fraudulent users.
Coin deposits by a typical patron of the public telephone are
communicated to the St Operator
Services System (OSS) by bursts of certain dual-tone signals. These
signals consist of the two frequencies 1.7 KHz and 2.2 KHz simul-
taneously, which are detected in end-office and tandem-office environ-
ments to provide accurate coin deposit detection.
There are two types of interference that are encountered by outside
origin. These are talkdown and talkoff. Talkdown is the failure to
recognize a valid dual-tone signal because of interference from
superimposed speech or other noise that may be from either the
originating coin line or the terminating end. Talkoff is the false
acceptance of speech, music, or background noises as valid coin
deposits. This obviously includes redbox tones, whistles, tape
reproductions, etc.
In order to combat the erroneous acceptance of false credit the
following methods have been defined and are to be employed
eventually (if they haven't already), according to recent
information.
Frequency Limits
- --------- ------
The detector must accept dual-tone signals if the frequencies
of both tones are within +/- 5% of their respective nominal
values of 1.7 KHz and 2.2 KHz. The detector must also reject
dual-tone signals if the frequency of either or both tones is
offset more than +/- 3.5% from its nominal value.
Frequency offsets of +/- 1.5 percent are the extremes expected from
properly designed and maintained coin telephones. The +/- 3.5 percent
constraint is imposed to minimize the width of the stop-band notch
filters in anti-fraud notch filters.
Signal Power and Twist
- ------ ----- --- -----
The detector must accept dual-tone signals if the individual
power levels of both tones are within 0 to -25 dBm0 and within
5 dB of each other. (Twist is the dB difference between
power levels of the two tones of a dual-tone signal)
The detector must reject dual-tone signals if the individual
poser level of either or both tones is below -30 dBm0.
The range 0 to -25 dBm0 is the maximum expected from properly designed
and maintained coin telephones and loops. The -30 dBm0 limit is
imposed to minimize the depth of the stop-band needed in anti-fraud
notch filters.
Pulse Timing
- ----- ------
Nickels, dimes, and quarters are represented by one, two, and five
dual-tone TONE-ON pulses. The dollar signal is represented by a
single long pulse. Each pulse is followed by a TONE-OFF interval.
The following chart shows the timing specifics for all coin generated
tones.
+----------------------------------------------------------------------------+
| | Within-Coin | End-of-coin Tone OFF (ms)|
|---------------------+-------------+-------------+-------+------+-----------|
| | TONE-ON (ms)| TONE-OFF(ms)| Must | Must |Allowed to |
| | Must Accept | Must Accept | Accept|Reject|Acc. or Rej|
|---------------------+-------------+-------------+-------+------+-----------|
| Nickel | 1 Pulse | 35 - 160 | ---- | >175 | <160 | 160 - 170 |
|---------+-----------+-------------+-------------+-------+------+-----------|
| Dime | 1st Pulse | 35 - 160 | 25 - 110 | | | |
|---------+-----------+-------------+-------------+-------+------+-----------|
| Dime | 2nd Pulse | 35 - 160 | ---- | > 75 | < 60 | 60 - 75 |
|---------+-----------+-------------+-------------+-------+------+-----------|
| Quarter | 1st Pulse | 20 - 100 | 20 - 110 | | | |
|---------+-----------+-------------+-------------+-------+------+-----------|
| Quarter | 2nd Pulse | 20 - 60 | 20 - 60 | | | |
|---------+-----------+-------------+-------------+-------+------+-----------|
| Quarter | 3rd Pulse | 20 - 60 | 20 - 60 | | | |
|---------+-----------+-------------+-------------+-------+------+-----------|
| Quarter | 4th Pulse | 20 - 60 | 20 - 60 | | | |
|---------+-----------+-------------+-------------+-------+------+-----------|
| Quarter | 5th Pulse | 20 - 100 | ---- | > 75 | < 60 | 60 - 75 |
|---------+-----------+-------------+-------------+-------+------+-----------|
| Dollar | 1 Pulse | 600 - 700 | ---- | > 75 | < 60 | 60 - 75 |
|---------+-----------+-------------+-------------+-------+------+-----------|
| Note: The detector is allowed to accept or reject tone-on and within-coin |
| tone-off durations outside their respective must-accept ranges. |
+----------------------------------------------------------------------------+
Methods of controlling talkdown and talkoff
- ------- -- ----------- -------- --- -------
Talkdown, is more of a transmission error problem that is generated
by interference from superimposed speech or ambient noise. This
noise comes from the originating coin line or from the terminating
end. Talkdown results in the failure of the detector to recognize
a valid dual-tone signal.
One of the main sources of talkdown is the improper muting of the voice
path during tone generation. This attenuated speech or ambient noise
power is superimposed on the coin signals which corrupts the signal.
Muting is accomplished by shorting out the speech path with a cap-
acitor. Minimum muting attenuation is 15 dB at 300 Hz, 25 dB at
1000 Hz, and 35 dB at 3000 Hz. The attenuated speech or ambient
noise power is superimposed on the coin signals which could cause
talkdown.
Some talkdown is also generated from the called party, operator
speech, or automated announcements. These signals can only reach
the detector by reflection through the trans-hybrid path at a 3-to-4
wire junction, which is usually located in the originating end
office.
Talkoff
- -------
Talkoff is the false acceptance of speech, music or background
noises as valid coin deposit signals by a detector. This is
what registers a valid deposit when no actual money is deposited.
In order to combat, a few countermeasures are expected to be employed.
o The call must be terminated or routed to an operator if the
total amount due for an initial deposit or a subsequent deposit
has been received within an overall session timeout period.
o The overall session timeout must be an adjustable parameter with
a default value of 45 to 50 seconds.
Intentional talkoff can be induced by playing loud music into the
coin telephone by doing this one hopes to get the detectors to produce
too many talkoff clusters. A talkoff cluster is a group of talkoffs
occurring within any 5-minute interval. Single quarter or dollar
talkoffs are also included in this definition of a cluster. In order
to combat this the following measures are being taken.
o Total talkoffs must not exceed 12 dollars in 70 hours of continuous
speech or music at a volume level of 0 vu referred to 0 TLP or,
instead, at an active speech level of +1 dBm0.
o The detector must not produce more than 12 talkoff clusters that
exceed 20, or 40, or 95 cents in 70 hours of continuous speech or
music at a volume level of 0vu referred to 0 TLP or, instead, at
an active speech level of +1 dBm0.
o Total talkoffs must not exceed 2 dollars in 200 hours of continuous
speech or music at -17 vu referred to 0 TLP or, instead, at an active
speech level of -16 dBm0.
Coin-Operated Telephone Fraud
- ------------- --------- -----
Fraud is possible by acoustically coupling accurate coin deposit
signals into the mouthpiece of the originating coin telephone, or
>from the called party end. Fraudulent signals coming from the
coin telephone end can only be stopped within the coin telephone
with a notch filter to filter out any external fraudulent signals.
In order to combat Fraudulent usage the following will be enacted.
o End- or tandem-office switching systems will be equipped with
detectors that monitor signals from the originating coin line.
The following methods combat far-end fraud:
o Sensing the direction of received coin signals and only
registering those coming from the coin line.
o Increasing the trans-hybrid path loss (using echo cancelers to
knock down the fraudulent signal's signal strength to that under
the detector's recognition threshold.)
o Inserting a 2200-Hz notch filter in the voice transmission path
from the far end only when the detector is expecting coin deposits.
The filters 3 dB bandwidth must be less than 600 Hz centered on
2200 Hz. and the out-of-band attenuation below 1500 Hz and above
3000 Hz must be less than 1 dB.
Conclusion
- ----------
The BOCs are now taking action against 'Redboxing' as well as
against some of their own equipment defects. It was only a matter
of time, of course. I have no idea how long this conversion will
take or even if it has started. There has been some indication
as some start of an anti-fraud campaign in my local area. I have
gotten word from some people that coin operated telephones have
not been accepting tones. I am unaware if these machines were
BOC operated or if they were COCOTS. I believe them to be BOC
coin operated telephones.

Now days it seems that Big Brother is always listening in. Wherever you
are, whatever you do, there is a good chance that your private conversations
aren't so private. The FBI, Secret Service, DEA, local police, and dozens of
other government agencies are definitely interested in what you have to say.
What can we do about this? Well, unfortunately they have the badges and the
guns, so we may as well get used to it. Since we can't beat'em, might as well
enjoy it, understand it, and learn something from it.
Mikes and Bugs
~~~~~~~~~~~~~~
Most FCC legal devices are found in the 150 to 174 MHz band, and other,
limited parts of the 40 to 952 MHz range. Here is a list of FCC approved bands
for wireless mike, room bugs, and body mikes. Also note that other bands MAY
be used with special FCC permission. (An "*" indicates a band that may be used
by vehicle tracking transmitters. More on that later)
42.02 to 42.94 MHz
44.62 to 46.58 MHz
47.02 to 47.50 MHz
72.00 to 76.00 MHz
150.995 to 151.49 MHz *
153.74 to 154.445 MHz *
154.635 to 156.25 MHz *
157.05 to 157.11 MHz
158.715 to 159.645 MHz
166.25 to ------ MHz
170.15 to 173.40 MHz
453.05 to 453.95 MHz
458.05 to 458.95 MHz
460.025 to 460.625 MHz
462.95 to 462.975 MHz
465.025 to 465.625 MHz
467.95 to 467.975 MHz
470.00 to 512.00 MHz
821.00 to 824.00 MHz
866.00 to 869.00 MHz
If the purpose of the surveillance is not going to be used for criminal
prosecution, agencies are reported to work outside of FCC restrictions to
avoid detection. Though the FCC declares them illegal, devices have been
found that work in the government, TV broadcast, and even aero bands. The
following areas of the spectrum are known to be used on occasion:
73.00 to 74.6 MHz
137.00 to 138.00 MHz
216.00 to 222.00 MHz
400.00 to 406.10 MHz
608.00 to 614.00 MHz
Surveillance Repeaters
~~~~~~~~~~~~~~~~~~~~~~
Law enforcement agencies use mobile repeaters and extenders to retransmit comms
of interest. These low power (about 15 watts) repeaters are usually located in
patrol cars. This allows the officer to monitor the surveillance device from
outside his car via portable handheld transceiver. These are often simply
little used channels of their normal assigned bands. Surveillance mobile
repeaters are still quite weak, so if you can hear it, it's probably close by!
(under your bed ?!) Here is a list of mobile repeaters used by state
enforcement agencies:

Vehicle Tracking Transmitters
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Enforcement agencies often need to track suspect vehicles, cargo
shipments, or packages. Tiny transmitters are used that emit a quarter second
beep once each second. Some contain motion detectors that beep once every ten
seconds when not in motion. This saves battery life and of course provides
some information as to the status of the tagged object. Vehicles used for
tracking these transmitters are easy to spot. Look for four identical
antennas mounted in a square configuration. (Hmm, that pizza-van has been
parked across the street for over four days!)
Remote Control Surveillance
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Some transmitters can be set for remote control operation. That way they
can be turned off during times of inactivity to conserver power. They can also
be turned off to avoid detection during countersurveillance sweeps to avoid
detection. Look for these types of systems in the 72.01 to 72.99 MHz and 75.99
MHz bands (20 kHz steps). Some are thought to operate in the 300 to 350 MHz
band as well.

TRW keeps tabs on the financial standing of businesses, both big and small.
Just about everyone from AT&T to Billy-Bud's Bait Shop is referenced in their
files. Just exactly what kind of information do they have? What kind of data
do they give to creditors. Exactly what kind of things could reflect
negatively on your credit standing? Following is a sample of a typical TRW

RISK PROFILE
------------
CHANCE OF ACCOUNT ENTERING SERIOUSLY DEROGATORY STATUS WITHIN 1 YEAR: 3%
THE PERCENTAGE ABOVE IS CALCULATED BY THE NATIONAL RISK MODEL, WHICH USES A
POINT-SCORING SYSTEM THAT ADDS OR SUBTRACTS POINTS BASED ON A PROPRIETOR'S
CREDIT BEHAVIOR. THE MODEL ONLY EXAMINES INFORMATION THAT APPEARS ON A
PROPRIETOR'S SBAR REPORT, AND DOES NOT TAKE INTO ACCOUNT OTHER DATA, SUCH AS
THE PROPRIETOR'S INCOME OR NET WORTH.
THE PERCENTAGE, REFERRED TO AS A PROBABILITY PERCENTAGE, INDICATES THE
LIKELIHOOD OF A PROPRIETOR BECOMING DEROGATORY IN HIS PAYMENT HABITS.
DEROGATORY CREDIT BEHAVIOR CAN BE DEFINED AS MAINTAINING ACCOUNTS THAT HAVE
DEVELOPED INTO COLLECTION ACCOUNTS, REPOSSESSIONS, CHARGE-OFFS OR BANKRUPTCIES.
THE PERCENTAGES RANGE FROM 0% TO 100%. AS INDICATED ON THE SBAR, APPROXIMATELY
85% OF ALL PROPRIETORS HAVE A 0%-15% CHANCE OF BECOMING SERIOUSLY DEROGATORY
WITHIN 1 YEAR; 12% HAVE A 16%-49% CHANCE; AND 3% HAVE A 50%-100% CHANCE.
IN GENERAL, PROPRIETORS WITH A PROBABILITY PERCENTAGE OF 0%-15% ARE A GOOD
RISK; THOSE WITH A PERCENTAGE OF 16%-49% ARE A MEDIUM RISK; AND PERCENTAGES OF
50%-100% INDICATE A POOR RISK.
YOU MAY WANT TO IDENTIFY SEVERAL RANGES OF PERCENTAGES THAT YOU CONSIDER TO BE
GOOD, MEDIUM, AND POOR RISKS, BASED ON HOW MUCH RISK YOU ARE WILLING TO TAKE
IN EXTENDING CREDIT.

STATUS CHARACTERISTICS
STATUS CHARACTERISTICS DEFINE THE SPECIFIC CONDITIONS WHICH CONTRIBUTE TO A
PROPRIETOR'S PROBABILITY PERCENTAGE. ONE TO FOUR CHARACTERISTICS ARE DISPLAYED
ON THE SBAR IN ORDER OF IMPORTANCE, AND GIVE YOU ADDITIONAL INSIGHT INTO A
PROPRIETOR'S PERSONAL CREDIT HISTORY.
FOR PROBABILITY PERCENTAGES OF 16%-100%, THE STATUS CHARACTERISTICS ARE A
SIGNIFICANT INDICATOR OF WHY THE PERCENTAGE IS HIGH. FOR PERCENTAGES OF 0%-15%,
THE CHARACTERISTICS ARE NOT A SIGNIFICANT INDICATOR, AND SHOULD NOT CARRY MUCH
WEIGHT IN YOUR CREDIT-GRANTING DECISION.
TO HELP YOU BETTER UNDERSTAND AND INTERPRET THE MEANING OF THE STATUS CHAR-
ACTERISTICS, A "GLOSSARY OF STATUS CHARACTERISTICS" IS INCLUDED IN THE SBAR
BROCHURE AVAILABLE FROM YOUR ACCOUNT EXECUTIVE.

Garage door openers employ a DIP switch that the owner sets to his own
personal "code". The code is actually just a binary number created by the
on/off positions of the switch. The device discussed here will enable you to
open any automatic garage door (aside from some of the new dual switch models).
The opener employs a 555 timer as a pulse generator to transmit pulses to a
binary counter. Each pulse will increment the binary counter by one. You can
adjust the speed of the counting by turning R1. You will have to experiment to
find the best speed. If it is too fast, the signal will not be long enough to
open the door. Normally, about 2.5 minutes to complete all 1024 combinations.
As you hit the switch, it will begin counting up, lighting the leds for the
corresponding switches as it turns each on. This will serve as a reference so
that you can set any opener to.
To connect to the garage door opener, first desolder the DIP switches from the
door opener and solder an IC socket into where the DIP switches were. (This
will allow you to put the DIP switches back, when operating in normal mode.)
Second, you should connect the output to a wirewrap IC socket. If you mount
the IC socket on your pc or perfboard you can use the socket to plug right into
the door opener. When connecting the output, be sure that the connections on
the wirewrap socket correspond to the ON setting of the DIP switches.

+ Air Fone Frequency Allocation +
+ +
+ Based on information from Leroy Donnelly +
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Ever wonder just what those trendy jet-setters talk about on their in-flight
air to ground radiotelephones? The FCC has issued rules on allocation of the
849-851/894-895 MHz bands for air-ground radiotelephone service. Using this
information it is quite easy for ANYONE with a scanner to intercept these
calls. Nothing that is said over the air should be considered secure.
Competiters, enemies, and the news media could be tuning in on "private"
conversations at any time. Here is the information on how it is all set up.
The new action (effective as of September 9, 1991)
1) changes channel spacing from GTE Airfone Inc.'s de
facto standards;
2) orders GTE to make its service available to other
air-ground licensees at non-discriminatory rates;
3) divides each channel block into 6 control channels
(P-1 through P-6) and 29 communications channels
(C-1 through C-29);
4) provides for a communications channel bandwidth of 6
kHz;
5) gives GTE 22 months to modify its current control
channel scheme; during this period, GTE can use
the lower 20 kHz of each channel block, which
includes channels C-1, C-2, and C-3, for control.
GTE then has another 38 months during which it can
only use a 3.2 kHz control channel in channel C-2
of each channel block. After these transition
periods end (September of 1996), GTE must switch
to control channels marked P-1 through P-6 in the
tables below;
6) empowers the FCC to assign exclusively one control
channel to each air-ground licensee;
7) limits the ERP of airborne stations to 30 watts;
maximum, and that of ground stations to 100 watts
maximum;
8) limits the ERP of ground stations to 1 watt when
communicating with aircraft on the ground.

This article contains information pertaining to VeriFone Credit Card
Authorization machines. I have not run across any files containing information
on this subject, but if anyone knows where I can find more information about
these little grey boxes I would appreciate it.
The VeriFone comes under different names. This file is from hacking a ZON Jr XL,
but I have also seen ones that look much similar under the name TRANZ. If
anoyone has any information on the similarities/differences of these machines
I would appreciate the info....
THIS FILE IS FOR INFORMATIONAL PURPOSES ONLY.
THIS FILE IS INTENDED FOR AUTHORIZED PERSONS IN UNDERSTANDING/OPTIMIZING
THIER MACHINE.
THE AUTHOR TAKES NO RESPONSIBILITY FOR THE ACTS OF OTHERS.
WARNING! Please contact MichiganBankCard and all other applicible agencies
before reading this file.
This is the basic layout the machine, and some information on how it works.

CLEAR:
Pressing CLEAR at any time brings the VeriFone back to the READY state.
BACKSPACE:
Used to erase previously enterd characters.
ALPHA:
Used to scroll through the letters on each key. Pressing an 8 will display
8. Pressing ALPHA will change this first to T, and successive presses will
change this to U, then V, then T again.
FUNC/ENTER:
Usually a blue key where all the other keys are grey. Used to indicate
end of input when entering information, or to change the FUNCTIONS of
the keys to do alternate things.
(1)SALE:
Pressing 1(SALE) means you want to process a sale transaction. The VeriFone
will ask for the credit card number. The unit uses the CC number algorithm
to check this number and can display BAD CC NUMBER. The expiration date
may be entered at this time at the end of the CC nunmber, or after pressing
ENTER it will ask for the expiration date which is of the form mmyy or myy.
This information can be entered with the keypad or by sliding the credit card
through the CC reader slot.
Then the amount of the transaction is entered (without a decimal point and
without rounding the cents) followed by ENTER.
The VeriFone calls in to get a 6-digit authorization number. Usually this
is 6 numbers, but I have seen it composed of two letters followed by 4 digits
as well. It usually begins with AP which indicates approval.
If the transaction in not approved it returns various messages depending on
the reason. This could be DECLINE, meaning there is not enough money left
in the account; CALL-HOLD meaning there is enough money but someone has
done an AUTHORIZATION (not a SALE) which reserves some of the accounts money
and will be released after 7-10 days if not DRAFT is recieved; or just
CALL, which usually means the card is stolen or cancelled.
This transaction is stored in the batch, if approved, and the approval number
is displayed.
Pressing CLEAR returns the unit to its READY state.
(2)CREDIT:
Pressing 2(CREDIT) is used for the processing of a CREDIT (as opposed to SALE)
draft. Information same as above but the VeriFone does not call to get any
kind of authorization. After all the information is enterd the unit
retunrs to the READY state.
This information is stored in the batch with CI in place of MC, VI, etc. to
indicate a credit.
(3)FORCE:
Similar to a SALE except that the unit does not call to get an approval
number. Used when an transaction is DENIED, or erased. The unit does not
call to get an approval number. The information is stored in the batch.
(4)UNDEFINED:
Could be used for special services, like AMEX transactions or Collection
Services.
(5)CHECK:
Something to do with authorization of checks and check cashing but I'm
unclear about this one.
(6)AUTH:
Like SALE, returns approval or decline code but is not stored in batch.
Places a HOLD on the card for the entered amount for 7-10 days. A sales
draft can be sent in based on this, otherwise the HOLD will be removed.
Used to reserve money on the account or to check to see if the card is good.
(7)UNDEFINED:
Can be used for more special services.
(8)CASH-MGMT:
I have no idea.
(9)BALANCE & SETTLE FUNCTIONS:
At the end of day or whenever the batch is filled (about 100 transactions)
a batch number is obtained. This is a nine digit number that is used to
reference the batch of transactions when dealing with credit corporations.
First one must BALANCE the batch. Pressing 9 (to BALANCE) will ask for a
password (stored in location 053). Enter this number and press ENTER.
The VeriFone will ask for the number of transactions which is simply a count
of the number of transactions followed by ENTER. If this is correct then
it will ask for total amount, which is the total amount of all the
transactions (the decimal point is not entered but the cents must not
be rounded so that if the total was $174.30 it would be 17430) followed by
ENTER. If either the # of transactions of total amount is incorrect
then the VeriFone diaplays the first entry of the batch which is the
last 5 digits of the credit card number followed by credit card type (VI, MC,
etc.) followed by the 6 digit authorization number, followed by the
amount of the transaction. By entering digits at this time, followed by
ENTER,the amount of the transaction can be changed. The batch is scrolled
forward by pressing ENTER.
When the information is correctly entered, The VeriFone displays READY (or
whatever is stored in location 030.) When the 9 is pressed again (to SETTLE)
it calls to process the batch. It transmits its information (if any of the
information has been changed, it sends it twice) and recieves the 9 digit
batch number, which it displays.
(0)AUTO:
An auto-dialer of some sort. Phone numbers can be stored in memory, and
pressing AUTO will dial it for you and tell yo to pick up the handset when
it is finished. I'm not sure how to use it.
MEMORY FUNCTIONS:
To review the VeriFone's memory, press:
FUNC,7
The screen will display
=
and will wait for you to enter three numbers or press ENTER which will start
at 000. Pressing ENTER will increment the location displayed, ALPHA will
decrement.
To change the Verifone's memory, press:
FUNC,8
You are asked for a password, but this is not the password stored at location
053 (this password is used for functions like getting batch numbers, clearing
the batch, changing the information in the batch, etc.) On the two machines
I have checked this password is 166831, which I obtained to when the local
authorization phone number was changed. It would call this number twice
getting a "The number you have called has been changed . . ." message,
then would call the 1-800 number.
Valid Memory Locations of form ### are:
000-399, 400-412, 500-512, 600-612, 700-712, 800-812, 900-912

108 SALE Message display when 1(SALE) key is pressed
208 CREDIT Message display when 2(CREDIT) key is pressed
#08 Locations 108,208, . . . are messages displayed when
that key is pressed. Not true for 008. Can
be changed to whatever you want.
311-399 <EMPTY>
Many of the other locations contain long strings of characters that are some
sort of password/id/information (up to 40 characters I think) that the
VeriFone passes when it calls in, others are empty or used to store new
information. Chnaging these can upset the functionality of the unit.
Local numbers are called first, and if no successful connection, then the
1-800 number is called.
CLEARING THE BATCH:
Pressing
FUNC,6(?)
followed by the password (location 053) followed by ENTER. The VeriFone asks
"CLEAR BATCH?". Pressing ENTER clears the BATCH, CLEAR cancels this. To
restore the BATCH, FORCE would be used to restore this information insted of
SALE as SALE would obtain a second transaction and approval number.
UNIT SEND & UNIT RECIEVE:
Pressing
FUNC,*
or
FUNC,#(?)
does UNIT SEND or UNIT RECIEVE which does some sort of UPLOAD/DOWNLOAD
functions. I'm not sure how this one works.
Useful if important memory locations of the VeriFone are chnaged and

Cordless Phone Update
~~~~~~~~~~~~~~~~~~~~~
This is a little extra info on cordless phone frequencies from issue 01. I
decided that there are times that the handset frequencies could also be handy
for when the base itself is out of range. Note that a good many cordless
phones handsets are simplex, so the conversation will be one-sided. Here is
the list again, with the updated handset frequencies.
channel base handset
1 46.610 49.670
2 46.630 49.845
3 46.670 49.860
4 46.710 49.770
5 46.730 49.875
6 46.770 49.830
7 46.830 49.890
8 46.870 49.930
9 46.930 49.990
10 46.970 46.970
