9.2 Testing Your Phone

The test function enables you to verify that your phone’s lights and display are operating properly.
To test the phone's lights and display:
1. With the phone idle (on-hook), press and release MUTE, then press the following numbers on the dial pad: 8 3 7
8 # (which stands for TEST).
The display should indicate the self-test has started. If the test is successful, the message “Self test Passed #=end”
displays; if the test is not successful, the message “Self test Failed #=end” displays instead.
2. To return to the phone screen, press #.
If nothing appears on the display and the phone is receiving power, your phone may need to be replaced. Contact
your system administrator for assistance or additional troubleshooting information.
