Troubleshooting

Test a working telephone at the telephone wall jack. If another telephone

has the same problem, the problem is the telephone wall jack. Contact

your telephone service provider (charges may apply).

Other electronic products such as HAM radios and other DECT phones

can cause interference to your cordless telephone. Try installing your

telephone as far away as possible from these types of electronic devices.

Completely remove then replace the battery. Place the cordless handset

in the telephone base. Wait for the cordless handset to reestablish its

connection with the telephone base. Allow up to one minute for this to

take place.

Your telephone line cord might be defective. 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 and

charger 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.
