Testing Your Phone
The Test feature lets you verify that your telephone's LEDs are operating properly.
Testing the Telephone's LEDs
To test the telephone’s LEDs:
1. With the telephone idle (on-hook), press and release the Hold ( ) button, then dial this
sequence: 8 3 7 8 #.
The phone immediately begins the self-test. All LEDs (lights) flash on, then off continuously
(for 500 milliseconds each) to indicate the self-test was successful. If the self-test fails, the
LEDs flutter on and off for a shorter period of time (50 milliseconds each).
2. Press # (the pound button) to end the test procedure.
If the LEDs are not illuminated and flashing and the phone is receiving power, your phone may
need to be replaced. Contact your System Administrator for assistance or additional
troubleshooting information.
Basic Troubleshooting Chart
Problem/Symptom Suggested Solution
Phone does not activate
after connecting it the first
time
Unless your System Administrator has already
initialized your telephone, you may experience a delay
of several minutes before it becomes operational. Upon
plug-in, your telephone immediately begins
downloading its operational software, its IP Address
and any special features programmed by your System
Administrator from the server to which it is connected.
Report any delay of more than 8-10 minutes to your
System Administrator.
Phone does not activate
after a power interruption
Allow a few minutes for re-initialization after
unplugging, powering down the phone, server
problems or other power interruption causes.
If both Message indicator LEDs are flashing, the
telephone is not registered. Follow the procedure for
Registering the Phone
on page 17.
