FIRST CALIBRATION SCREEN  SECOND CALIBRATION SCREEN
 
14.  The first calibration dot appears in the upper right-hand corner of the screen. Touch the center of this 
circle with your finger. Finger position will be verified by an audible tone. 
15. The second calibration dot appears in the lower left-hand corner of the screen. Touch the center of 
this circle with your finger. The VGM enters the Test Screen mode accompanied by an audible tone. 
16. Touch the screen and note that the crosshair centers beneath your fingertip. Touch all four corners 
and the entire bottom edge of the touchscreen. Touch the EXIT TEST button on the screen when 
done. 
17. TRACKING TEST
  Press the SETUP button. Touch the TEST SCREEN button on the screen. 
TRACKING TEST SCREEN 
18.  A cross will appear in the center of the test screen. Touch the center of the cross and observe that the 
crosshair centers on the cross. The crosshair will follow your finger as you move it across the screen. 
19.  Touch the EXIT button on the screen. 
 
If the crosshair was not centered on your finger, note the distance and direction it is off center. Return 
to the calibration screen and place your finger on the screen slightly away from, but in the same 
general direction and distance, from the dot to where the crosshair was off center. 
 
Example:  If the crosshair appears slightly below where you touched the screen, place your finger just 
below the calibration dot. If the crosshair appears slightly above and to the right of where you touched 
the screen, place your finger just above and to the right of the calibration dot. 
 
Repeat the previous step for the second calibration dot. W hen the crosshair is centered on your finger 
the screen is accurately calibrated. To accurately calibrate the screen, several attempts may be 
required to compensate for the individuality of the touchscreen and its mounting on the CRT. Use the 
CALIBRATE mode as needed to calibrate the screen as accurately as possible. 
 
NOTICE 
If the existing touchscreen cannot be calibrated correctly, troubleshoot and 
repair or replace any defective components before proceeding. The kit electronics will 
not make these symptoms go away.

REAR OF CABINET WITH DOOR OPEN 
1.  Unplug VGM. Insert key or keys into rear lock or locks and turn clockwise to unlock. Open cabinet 
door. 
 
DANGER:  HIGH VOLTAGE CRTs and their power supplies can retain energy for long 
periods of time after power has been turned off. This is especially true when a defective 
circuit prevents a normal discharge. Connect a very well insulated ground strap to the 
metal chassis. Slide the free end of the strap under the CRT anode cap until contact is 
made. W ait two minutes for charge recovery, then discharge the anode a second time. 
 
DANGER:  RADIATION The high voltages used in the video monitor assembly can 
generate X-rays under fault conditions. Do not substitute high voltage components or 
modify the circuit without factory authorization. Follow the manufacturer’s directions for 
measuring and adjusting the CRT anode voltage. 
2. 
GROUND WIRE Remove ground wire, if present. 
3.  Locate each of the original equipment manufacturer’s cable and wire connections prior to 
disconnecting them from the VGM electronics. 
4. 
TOUCHSCREEN If the touchscreen connector cable (a rectangular connector) is connected to the 
CPU Board Assembly at J5, disconnect it from the CPU Board Assembly. If a separate touchscreen 
controller connector cable is also present, disconnect it (a D-subminiature connector) from the CPU 
Board Assembly. You may have either or both connectors. 
5. 
CONTROLLER Remove the touchscreen controller from the VGM. Detach touchscreen connector 
cable from the controller, if present. Leave the cable inside the cabinet and retain mounting hardware.
