3.2.3 Keypad Test
To test the customer keypad, leave the interface board in the normal operations mode. As a first
test, press each key one at a time and make sure the customer buzzer beeps when each key is
pressed. Clear those entries by pressing the * key (some older units have a P key), then enter
the two test sequences at the customer keypad: 123450 and 67890. After each entry, go to the
POS4000 main console and read the customer code displayed on the bottom right of the
console display. The displayed value should match the number that was entered at the interface
board.
If one or two keys do not beep when pressed at the car wash entrance, it is likely a keypad
failure. The keypad can be checked by making the following continuity checks: First, disconnect
the KEYPAD PLUG from the interface board and check for continuity between the connector
pins specified when a particular key is depressed.
