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. 

 

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.
