Troubleshooting
Other electronic products such as HAM radios and other DECT phones can cause
interference with your cordless phone. Try installing your phone as far away as
possible from these types of electronic devices.
Test a working telephone at the telephone wall jack. If another telephone has the
same problem, there may be problem with the telephone wall jack. Contact your
telephone service provider.
The telephone line cord may be defective. Install a new telephone line cord.
I cannot register a cordless headset.
Only one headset can be registered at a time. If you have multiple handsets and
headset to register, please follow the instructions on pages 63 and 64.
If you have already registered the maximum numbers of handsets and/or headset
that the telephone system accommodates, you need to follow the deregistration
instructions before registering a headset. Refer to Expand your telephone system
on page 63 and Replace a handset/headset on page 65.
Make sure that all registered handsets and the telephone base are in idle mode when
registering a headset.
Follow the steps on page 74 for the common cure for electronic equipment, then try
again to register a headset.
My caller ID features are not working properly.
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.
The caller may not be calling from an area which supports caller ID.
Both your and your caller’s telephone service providers must use equipment
compatible with the caller ID service.
The caller ID information shows after the first or second ring.
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. The filter prevents noise and caller ID problems caused by
DSL interference. Contact your DSL service provider for more information about
DSL filters.
The telephone does not receive caller ID or the telephone does not show
caller ID during call waiting.
Make sure you subscribe to caller ID with call waiting features provided by your
telephone service provider.
The caller may not be calling from an area which supports caller ID.
Both your and your caller’s telephone service providers must use equipment
compatible with caller ID service.
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. The filter prevents noise and caller ID problems caused by
DSL interference. Contact your DSL service provider for more information about
DSL filters.
