IMPORTANT: In order to use all of the features of this telephone, you
must subscribe to two separate services available from your local telephone
company: the standard Name/Number Caller ID Service to know who is
calling when the phone rings and Caller ID with Call Waiting Service to know
who is calling while you are on the phone.
INSTALLATION NOTE: Some cordless telephones operate at frequencies
that may cause or receive interference with TVs, microwave ovens, and VCRs.
To minimize or prevent such interference, the base of the cordless telephone
should not be placed near or on top of a TV, microwave ovens, or VCR. If such
interference continues, move the cordless telephone farther away from these
appliances. Certain other communications devices may also use the 2.4GHz
frequency for communication, and, if not properly set, these devices may
interfere with each other and/or your new telephone. If you are concerned
with interference, please refer to the owner's manual for these devices on how
to properly set channels to avoid interference. Typical devices that may use the
2.4GHz frequency for communication include wireless audio/video senders,
wireless computer networks, multi-handset cordless telephone systems, and
some long-range cordless telephone systems.
