Checking the Front Panel Keys
To check the front panel keys, push each key and compare the name in the Key Label box to the name
physically labeled on the key cap. These names are also in
Table 4-2
below.
•
If all the key names are correct, then the front panel keypad is working. If some of the keys are not
working, suspect a faulty keypad. To replace the keypad, refer to
“Replacing the A1 Keypad Assembly”
on page 7-14
.
•
If none of the keys are working correctly, suspect a faulty A3 front panel interface board. To replace the
A3 front panel interface board, refer to
“Replacing the A3 Front Panel Interface Board” on page 7-14
.
