Troubleshooting
Your telephone line cord might be malfunctioning. Try installing a new 
telephone line cord.
My caller ID isn’t working.
Caller ID is a subscription service. You must subscribe to this service from 
your telephone service provider for this feature to work on your telephone.
Your caller must be calling from an area that supports caller ID.
Both your and your caller’s telephone service providers must use caller ID 
compatible equipment.
Make sure the home area code is set correctly in the telephone (see  
Home area code on page 14).
If you subscribe to high-speed Internet service (DSL - digital subscriber line) 
through your telephone line, you must install a DSL filter between the 
telephone line and the telephone wall jack (see Telephone base installation 
on page 4). The filter prevents noise and caller ID problems caused by DSL 
interference. Please contact your DSL service provider for more information 
about DSL filters.
My telephone does not receive caller ID when on a call.
Make sure you subscribe to caller ID with call waiting features provided by 
your telephone service provider. Caller ID features work only if both you 
and the caller are in areas offering caller ID service, and if both telephone 
service providers use compatible equipment.
A   icon shows on the display and I don’t know why.
Your telephone has voicemail indication that is separate from the built-in 
answering system. If   appears on the display, then your telephone has 
received a signal from your telephone service provider that you have a 
voicemail message waiting for you to retrieve from your telephone service 
provider. Contact your telephone service provider for more information on 
how to access your voicemail.
I cannot retrieve voicemail messages.
Your telephone has both a built-in answering system and voicemail 
indication. They are independent features and each alerts you to new 
messages differently (see Answering system and voicemail on page 41). 
If you subscribe to voicemail service from your telephone service provider 
(charges may apply), contact your telephone service provider for more 
information on how to access your voicemail.
Incomplete messages.
If a caller leaves a very long message, part of it may be lost when the 
answering system disconnects the call after four minutes.
