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.
Operation panel SP mode > Screen Device Settings > Panel Self Check > MultiTouch
