Range
Nominal values of the DECT system are:
T
164 feet (50 meters) – Indoor
T
984 feet (300 meters) – Outdoor
The telephone is designed to achieve a maximum range of up to 350 feet (depending
upon the environment), by transmitting and receiving according to the highest
specifications set forth by the FCC. We have rated this phone 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 of 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 has 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 can 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
Radio interference may occasionally cause buzzing and humming in your cordless
handset, or clicking noises in the base unit. This interference is caused by external
sources such as TV, fluorescent lighting, or electrical storm. Your unit is NOT
DEFECTIVE. If these noises continue and are too distracting, 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 of interference. For best performance, ensure that
the antenna on the base unit is fully extended.
In the unlikely event that you consistently hear other voices or distracting
transmissions on your telephone, you may be receiving radio signals for another
cordless telephone or other source of interference.
