Management and Troubleshooting
Overview
This chapter provides helpful information for:
• Testing your telephone to be sure it is operating correctly.
• Basic Troubleshooting; this chart provides the most common problems an end user might
encounter and suggested resolutions.
• Application-specific troubleshooting; this chart describes problems and solutions specific to
phone applications; Speed Dial, Call Log, or Web Access.
• Resetting or power-cycling your phone, when Basic Troubleshooting does not resolve a problem.
Testing the Telephone's Lights and Display
1. With the telephone idle (on-hook), press and release the Mute button, then press the following
numbers on the dialpad: 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. Press # to return to the Phone screen.
• 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.
