Troubleshooting
SM 8-59 D0CA/D0C9/D0C8/D0CB
Symptom Solution
The touch panel’s coordinates have
shifted substantially, resulting in not
being able to execute its calibration.
• Connecting a commercially available USB mouse
enables the same operation as the touch panel. So
you can execute the calibration
• Execute the Panel Self Check, or the TouchPanel
Calibration
• Execute the MultiTouc h Calibration.
• If the shift occurs even after turning the power and
then back ON, check the battery voltage of the
operation panel’s main controller board.
• Replace the main controller board.
• Replace the operation panel unit (you need to
transfer user information, and reinstall the
applications, etc.). Refer to "Factory Reset and
Restoration".
Cannot enter the SSP mode. If using the screen in a Classic Application, it does not
support multitouch, so you cannot enter the SSP mode
by the normal operation.
Instead, use the EX3 key. Press and hold the EX3 key,
and then press the "System/Copy" button in the SP
mode menu.
