Appendix
Troubleshooting
Test a working phone at the phone jack. If another phone has the same
problem, contact your telephone service provider (charges may apply).
Your line cord may be defective. Try installing a new 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 phone.
The 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.
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 4). 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. Caller ID features works only if both you and the
caller are in areas offering caller ID service, and if both telephone service
providers use compatible equipment.
Common cure for electronic equipment.
If the telephone does not seem to be responding normally, try putting the
cordless handset in the charger. If it does not fix the problem, do the following
(in the order listed):
1. Disconnect the cordless handset battery.
2. Wait a few minutes.
3. Connect telephone line cord to the telephone base and the telephone wall
jack.
