Touchscreen Malfunctions
Symptom Problem
Suggested
Solution
•
Touchscreen is not
accurate for two or
more players.
Dirty screen
Clean the entire cabinet frequently, especially the video
screen glass and the touchscreen area. It is not
necessary to switch off power to the VGM to clean the
unit. Apply an isopropyl alcohol or warm water to a
clean cloth or sponge, then use this to wipe the surface.
Do not apply the cleaner directly on the unit. Liquids
can drip into circuits and cause erratic VGM operation.
Overzealous
touching
Warn players to use only one finger at a time.
Simultaneous touches confuse the touch controller.
Poor
player
grounding
Some players may find that touchscreen response
improves when they touch the surface of the metal
cabinet with one hand as they operate the touchscreen
with the other hand.

Touchscreen
chooses incorrect
items or does not
respond when
certain areas are
touched.
Poor calibration
Unlock and remove cash door. Enter Menu System by
pressing the SETUP switch inside the coin vault. From
the SYSTEM SETUP menu, go to DIAGNOSTICS and
choose the CALIBRATE TEST (refer to Operation for
additional details). Use these tests to confirm that the
touchscreen is detecting and properly tracking finger
position in all areas of the screen.
From the DIAGNOSTIC menu, choose CALIBRATE to
adjust the touchscreen accuracy. Follow the on screen
instructions to optimize the touchscreen for sensitivity
and linearity.
