• 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 you and your caller's telephone companies must
use caller ID compatible equipment.
• If you subscribe to high-speed Internet service (digital
subscriber line - DSL) through your telephone lines, you
must install a DSL filter between the telephone base
and the telephone wall jack. The filter prevents noise
and caller ID problems resulting from DSL interference.
Please contact your DSL service provider for more
information about DSL filters.
• 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
companies use compatible equipment.
If the telephone does not seem to be responding normally,
try putting the cordless handset in the telephone base or
charger. If it does not seem to respond, do the following
(in the order listed):
• Disconnect the power to the telephone base.
• Disconnect the cordless handset battery, and spare
battery, if applicable.
• Wait a few minutes.
• Connect power to the telephone base.
• Re-install the battery, and place the cordless handset
into the telephone base.
• Wait for the cordless handset to re-establish its
connection with the telephone base. Allow up to one
minute for this to take place.
