Diagnostics and Maintenance
8.1.2 Touch Screen Calibration Loss:
Touch screens are factory calibrated. Calibration is stored in an EEPROM. If user faces any of the
following problems:
- Any press inside defined object boundary results in three short beeps.
- Undefined area performs a task of some other defined object.
User will have to calibrate the touch screen of the unit. Steps for calibrating the touch screen for OIS60
are as bellow:-
1. At power ON, press the center of the OIS60 screen for more than 7 to 8 seconds.
2. Press the top left corner of the screen. The unit will now go into Touch screen calibration mode. A
cross is shown at the bottom left with a message “Touch here with stylus”.
3. Touch the center of the cross with a pointed object (stylus recommended). You will get a next
screen showing a cross at the top right of the screen with a message “Touch here with stylus”.
4. Touch the center of the cross with a pointed object (stylus recommended). The screen has now
been calibrated and will return to its normal mode.
