Why is the light not coming on with a new Voice Mail Message?
Your phone system or service provider must provide “Visual” Message 
Waiting service for this function to work. Check with your system 
administrator for more information.
Why is my handset not working?
Check to ensure that the handset cord is fully connected to both the phone 
and handset. See the section 
on 
information. 
Why is my speakerphone not working?
If the speaker light goes out, the phone is set up to be used only with a 
handset. If the light stays on steady and you hear dial tone, you can 
alternate between the speakerphone and the handset by pressing 
See the section, 
on 
 for instructions on how to change 
the Set Audio feature.
Why is my display blank?
Ensure that power is being provided to your phone. If your Network does 
not provide Inline power over Ethernet, you can obtain an additional 
accessory, the a PoE inline power injector, to provide power over 
Ethernet locally to your phone. See the section 
 for details.
Why can I only see 1 option when the installer or user guide says there 
are more?
The telephone screen will only show 1option at a time. To see more, press 
the down arrow button 
.
Why does the telephone wobble?
Make sure the cords are routed properly through the back of the phone, as 
indicated in the section, 
 on 
the leg stands have been properly snapped into place.  Since the legs can 
be oriented in two different ways and in two different positions to offer 
four different phone viewing angles, check that both legs are oriented in 
the same direction and in the same position on either side of the phone.
