3-4. Touch Panel Problems
Problem
Possible cause and remedy
1. Touch operation is disabled.
• Touch panel operation may be disabled. Press the
button to
enable the operation. The
button lights up blue.
• Check that the monitor and PC are connected with a USB cable.
• Turn the monitor off and on.
•
If moisture or an object is on the touch panel surface, remove
it. (Refer to the Monitor User’s Manual (on the CD-ROM).) This
product automatically disables touch panel operations by detecting
moisture or any other object that may cause a malfunction on the
touch panel surface.
• Check that the power cord of the monitor and PC is connected to a
grounded main outlet. Failure to ground the equipment may result
in a malfunction.
• Hold down
for two seconds or more to perform touch panel
sensitivity adjustment. Do not touch the touch panel until the "Don't
touch the panel. Calibrating..." message disappears from the
screen.
•
Perform touch panel sensitivity adjustment using TPOffset.
• If two or more PCs are connected to the monitor, only one of them
can perform touch operations. Check that the monitor and PC used
for touch operations are connected with a USB cable.
