The Test feature allows you to verify that your telephone’s lights and display are operating
properly.

following numbers on the dialpad: 8 3 7 8 # (which stands for TEST).
The display indicates 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.

If nothing appears on the display and the phone is receiving power, your phone might 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 might experience
a delay of several minutes before it becomes
operational. Upon plug-in, your telephone
immediately starts 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 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.
Phone worked earlier but does
not currently appear to work Contact your System Administrator.
