Key-pad Testing
The front panel key-pad and the hand terminal key-pad can be tested using the facility in the
maintenance/calibration selection of the set-up menu.
The procedure to test the key-pad requires each key to be pressed in turn and to confirm the
correct key press on the display. Make sure the display shows only the appropriate key press.
Note:
Connecting the hand terminal disables the front panel key-pad.
