Checking the Front Panel Keys
To check the front panel keys, push each key and compare the decimal value in the Value
box under Keys to the key values in Table 4-6.
• If all the key values are correct, then the A1 front panel keypad is working. If some of
the keys are not working, suspect a faulty A1 keypad. To replace the A1 keypad, refer to
“Removing the A1 Keypad Assembly” on page 7-12.
• 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 “Removing the A3 Front
Panel Interface Board” on page 7-12.
