Troubleshooting
Before calling for repair services, make sure following checks for possible remedies to the encountered
symptoms.
Problem
The touch panel does
not respond.
Reaction is slow.
Some part on the screen
does not respond.
Caution
• You cannot use two touch panels by mounting them on two monitors connected to a single PC.
In such a case, you can operate only the touch panel mounted on the primary monitor.
• When the PC connected to the touch panel has other USB devices being connected, do not activate such devices
during the touch panel input operation. Otherwise, proper input may be interfered with.
- Is the USB cable connected properly?
- Did you install the TouchPanel driver and TouchPanel Setting Program?
- Are the batteries of the touch pen exhausted?
- Does the ID number of the touch pen match with that of the touch panel?
- Has the screen been exposed to direct sunlight or strong light?
Is an infrared-operated device used nearby?
Since the touch panel operates with infrared rays, a malfunction may
occur under these conditions.
- Did you touch the screen with a thin object less than approx. 6 x 6 mm?
Such a touch may not be detected with infrared rays, resulting in a
malfunction.
- Did you touch the screen while the PC was starting up or the USB cable
was being connected?
Such a touch is detected as a failure of the infrared transmitter/receiver
elements, leading to a malfunction.
