3.6 Calibration of the LCD Touch Panel
The LCD touch panel has lost calibration accuracy if the touch panel does not respond when

which received the input.

operation is called "Touch Panel Calibration". There is no need to perform this calibration when
this unit is purchased, because the touch panel has been calibrated.
NOTE

The touch panel calibration would then need be re-executed because the setting of
touch panel calibration becomes invalid if the [PWR] key is pressed.

then re-execute the touch panel calibration.
