Troubleshooting 
• 
Phone does not activate when connected for 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 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. 
• 
Display shows an error/informational message:  
Most messages involve server/phone interaction. If you cannot resolve the problem based on the 
message received, contact your System Administrator for resolution. 
• 
Speakerphone does not operate:  
Ask your System Administrator if your Speakerphone has been disabled.  
• 
Characters do not appear on the display screen:  
• 
See "Phone does not activate when connected for the first time" above.  
• 
Check all lines into the phone to be sure it is properly connected.  
• 
Check the power source to be sure your telephone is receiving power.  
• 
Perform the following Test procedure: 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, then report 
if the test was successful or failed. If nothing appears on the display, and the phone is 
receiving power, your phone may need to be replaced.  
• 
If the above suggested solutions do not resolve the problem, reset or power cycle the 
phone with your System Administrator's assistance. 
• 
No dial tone:  
Make sure both the handset and line cords into the phone are securely connected. Note that 
there may be a slight operational delay if you unplug and reconnect the phone. Contact your 
System Administrator if the problem persists. 
• 
Phone does not ring:  
Set your ringer volume to a higher level using the 
 and 
 Up/Down Volume keys. From 
another phone, place a call to your extension to test the above suggested solution. 
• 
All other IP problems:  
Contact your System Administrator.
