About Caller Identification 
Caller ID with Call Waiting features in 
this telephone let you see who’s call-
ing before you answer the phone, even 
when you’re on another call. These 
features require services provided by 
your local telephone company.
Contact your telephone service pro-
vider if:
•  You have both Caller ID and Call 

Waiting, but as separate services 
(you may need combined service).

•  You have only Caller ID service, or 

only Call Waiting service.

•  You don’t subscribe to any Caller 

ID or Call Waiting services.

You can use this phone with regular 
Caller ID service, and you can use its 
other features without subscribing to 
either Caller ID or combined Caller ID 
with Call Waiting service. There may be 
fees for these services, and they may 
not be available in all areas.
Caller ID features will work only if 
both you and the caller are in areas 
offering Caller ID service, and if both 
telephone companies use compatible 
equipment.
See Caller ID Operation, beginning on 
page 29, for more details about how 
these features work.

Telephone operating range
This cordless telephone operates with 
the maximum power allowed by the 
Federal Communications Commission 
(FCC). Even so, the handset and base 
can communicate over only a certain 
distance — which can vary with the 
locations of the base and handset, the 
weather, and the construction of your 
home or office. 
If you receive a call while you are 
out of range, the cordless handset 
might not ring — or if it does ring, 
the call might not connect when you 
press 

. Move closer to 

the base, then press 

 to 

answer the call.
If you move out of range during 
a phone conversation, you might 
hear noise or interference. To improve 
reception, move closer to the base.
If you move out of range without 
pressing 

, your phone will 

be left off the hook. To hang up prop-
erly, walk back toward the telephone 
base, periodically pressing 

until the call is disconnected.
