8.4.1 MULTITOUCH MISDETECTION BY THE OPERATION PANEL
DUE TO AN AM RADIO SIGNAL
MultiTouch is detected even though only a single point on the operation panel is
•
touched.
If there is an AM radio tower near the machine's location, the person using the
•
operation panel acts as an antenna and radio noise enters the operation panel. As
the result, in spite of only a single point being touched, the machine senses
MultiTouch.
Adjust the MultiTouch sensitivity of the operation panel.
