WARNINGS
Range
Your new telephone is designed to achieve the maximum possible range by transmitting
and receiving according to the highest specifications set forth by the FCC and IC. We
have rated this telephone to operate at a maximum distance with the qualification that the
range depends upon the environment in which the telephone is used. Many factors limit
range, and it would be impossible to include all the variables in our rating. The Maximum
Range rating of this telephone is meant to be used as a means of comparison against
other range claims.
Telephone Line Problems
The FCC and IC have granted the telephone company the right to disconnect service in
the event that your telephone causes problems on the telephone line. Also, the telephone
company may make changes in facilities and services which may affect the operation of
your unit. However, your telephone company must give adequate notice in writing prior to
such actions to allow you time for making necessary arrangements to continue
uninterrupted service.
If you are having trouble with your telephone service, you must first disconnect your
telephone to determine if it is the cause of your problem. If you determine that it is the
cause, you must leave it disconnected until the trouble has been corrected.
Radio interference may occasionally cause buzzing and humming in your cordless Radio Interference
Handset, or clicking noises in the Base Unit. This interference is caused by external
sources such as a TV, refrigerator, vacuum cleaner, fluorescent lighting, computer
equipment, or electrical storm. Your unit is NOT DEFECTIVE. If these noises continue and
are too distracting, please check around your office to see what appliances may be
causing the problem. In addition, we recommend that the Base not be plugged into a
circuit that also powers a major appliance because of the potential for interference. Be
certain that the antenna on the unit is fully extended when needed.
In the unlikely event that you consistently hear other voices or distracting transmissions on
your telephone, you may be receiving radio signals from another cordless telephone or
other source of interference. If you cannot eliminate this type of interference, you need to
change to a different channel.
