N O T I C E
When the 310A monitor is connected to the IBM-PC (or compatible)
and the character display is generated, a sympton can occur in
which the character display cannot be seen on the monitor. This
symptom can also occur when switching modes as with a Hercules
Graphics Card. Should this problem occur with your monitor we
recommend one of the following solutions:
SHORT TERM SOLUTION: Be sure to always turn on the computer
first, then the monitor.
LONG TERM SOLUTION: Locate resistor R-203 on the
motherboard inside the monitor. Disconnect or cut one leg
of the resistor from the motherboard. (When viewed from the
rear R-203 is at the top right hand corner of the
motherboard.)
This modification of the 310A will not void the two year
warranty. If you have questions or need additional assistance in
making this modification please call our technical support
department at (312) 595-6890.
