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.
