Restore the Cellular Freqs. on Your BC200/205XLT!
This is so simple that anyone can do it, and you have to be
REAL sloppy in order to damage your unit.
There is no soldering involved, but if you do happen to mess your
unit up: YOU AND ONLY YOU ARE THE ONE THAT IS RESPONSIBLE. We take no
responsiblity for any thing that might become of you or your radio!
This mod. will also void your warranty, so open your radio and
check it out to make sure you can pull it off before you begin the real
work.
Now that we are through with the usual backwash of "spooky"
information we can now begin.
1.) Take the antenna and battery pack off of the radio.
2.) With a Phillips-head screwdriver, remove the two screws at the
back of the radio. Then remove the two screws and the battery
spring at the base of the radio.
3.) GENTLELY! pull off the back of the radio.
4.) Locate the two screws at the bottom of the board, and
carefully remove them with a Phillips-head screwdriver.
(Be carefull not to damage any of the surrounding components.
This is not to tough to avoid, but warrants mentioning.)
5.) EVER-SO-GENTLELY! pull the front panel away from the scanner
frame.
6.) On the front panel part of the radio, locate the microprocessor
IC (labeled UNIDEN UC-1147, its the biggest black chip on the
board) and the 10K ohm (brown-black-orange) resistor positioned
right above the letters "DEN" in the word "UNIDEN" on the IC.
***** MAKE SURE YOU LOCATE THE RIGHT PART *****
7.) With a small pair of clippers, clip the resistor right in two.
Make sure not to disturb any components around the resistor.
Leave the ends of the resistor on the board, all you need to
do is just clip it enough so that there is a gap between the two
ends. Take care to clean the remiments, made by cutting the
resistor, of the board.
8.) Check to see that there is no damage and everything is tidy.
9.) CAREFULLY reasemble the radio in exactly the reverse order of
how you took it apart. Be careful to line up the pins to their
sockets in the lower, left-hand side of the radio.
***** FAILURE TO DO THIS CORRECTLY WILL RESULT IN A DISPLAY
ERROR. WHEN THE RADIO IS TURNED ON NOTHING WILL APPEAR ON THE SCREEN.
don't panic.
I've done this before. The malfunction can be fixed by taking
the radio back apart, carefully, and making sure those pins are
in the correct socket. I almost gave birth to a small cow when this
happened to me and I was very relived to find out that this was all
that was wrong.
10.) After you have tightened the screws, put the battery pack and
the antenna back on the radio. Then press "MANUAL, 845.0, E".
Within two seconds the freq 845.000 should pop up on the display.
Now you have completed the mod. for your scanner. I would now like
to welcome you to the world of the forrbiden freqs.! You will now
see the truth to the statement "Never say anything on a cellular
phone that you do not want anyone else to hear." Unfortunately
(but fortunately for us!!) there is an incredible number of people
that do not know this and you will be suprised at the information
broadcast across the airwaves.
Enjoy!
