LCD, Touch Screen Check and Calibration

Smart Panel Maintenance Mode
You should perform the following checks and calibrations:
• After replacing the operation panel or operation panel touch screen.
• After clearing the memory
• If the touch screen detection function is not working correctly
1. First, remove the cover plate on the left side of the operation panel so you can see the EX buttons.
2. These buttons are not labeled but reading from left to right, they are EX1, EX2, and EX3.
3. Next, enter the numbers to enter the Smart Panel maintenance mode, and display the Service
Screen. (Contact your supervisor if you do not know how to do this.)
