Troubleshooting
I experience poor sound quality when using the handset speakerphone.
For increased sound quality while using the handset speakerphone, place the
handset on a flat surface with the dial pad facing up.
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 phone.
The caller may not be calling from an area that supports caller ID.
Both your and your caller’s telephone service providers must use caller ID
compatible equipment.
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 cord and the telephone wall jack (page 5). The filter prevents noise and caller
ID problems resulting from DSL interference. Please contact your DSL service
provider for more information about DSL filters.
System does not receive caller ID when on a call.
Make sure you subscribe to caller ID with call waiting features from your telephone
service provider. The caller ID feature works only if both you and the caller are
in areas offering caller ID service, and if both telephone service providers use
compatible equipment.
System does not answer after the correct number of rings.
Make sure that the answering system is on. ANS ON should show on
the handset and the /ANSWER ON/OFF light on the telephone base should
be on.
If toll saver is activated, the number of rings changes to two when you have new
messages stored (page 36).
If the memory is full or the system is off, the system will answer after 10 rings.
In some cases, the answering system is affected by the ringing system used by
your telephone service provider.
If you subscribe to voicemail service, change the number of rings so that your
answering system answers before your voicemail answers (pages 36). To determine
how many rings activate your voicemail, contact your telephone service provider.
If there is a fax machine connected to the same telephone line, try disconnecting
the fax machine. If that solves the problem, consult your fax machine
documentation for information on compatibility with answering systems.
