Verifone PIN Pad Self-Tests
You can perform various standalone self-tests using the PIN pad keypad. To perform the self-
tests, the console to which the PIN pad is connected must have the configuration temporarily
changed to NO CONSOLE PRNT/PAD (See Section 7, Configuration - Console 1A+ and II+).
To perform each self test:
1. Press CLEAR, then 3. The PIN pad displays PASSWORD.
NOTE: If the PASSWORD prompt does not display, you may be pressing the 3 key too
slowly. Pressing the CLEAR and 3 keys quickly should produce the desired result.
2. Press 83746 and then ENTER.
If the password is incorrect, the idle prompt (--------) displays. Repeat Steps 1 and 2.
If the password is correct, the PIN pad displays the self-test menu (shown below). Once the
password has been accepted, press the numeric key of the desired test. Most tests exit
automatically. If the test does not exit automatically or you want to return to the idle prompt,
press CLEAR.
