Technical Information
16
This cordless telephone uses radio frequencies to allow mobility. There are certain difficulties in
using radio frequencies with a cordless telephone. While these are normal, the following could
affect the operation of your system.
Noise
Electrical pulse noise is present in most homes at one time or another. This noise is most intense
during electrical storms. Certain kinds of electrical equipment such as light dimmers, fluorescent
bulbs, motors, and fans also generate noise pulses. Because radio frequencies are susceptible to
these noise pulses, you may occasionally hear them in your Handset. Generally they are a
minor annoyance and should not be interpreted as a defect in your system.
Range
Because radio frequency is used, the location of the Base Unit can affect the operating range.
Try several locations in your home or office and pick the one that gives you the clearest signal to
the Handset.
Interference
Electronic circuits activate a relay to connect the cordless telephone to your telephone line. These
electronic circuits operate in the radio frequency spectrum. While several protection circuits are
used to prevent unwanted signals, there may be periods when these unwanted signals enter the
Base Unit. You may hear clicks or hear the relay activate while you are not using the
Handset. If the interference occurs frequently, it can be minimized or eliminated by relocating
the Base Unit. You can check for interference before selecting the final Base Unit location by
plugging in the telephone.
NOTICE:
This cordless telephone uses radio communication between the Handset and the Base Unit and
may not ensure privacy of communication. Other devices, including other cordless telephones,
may interfere with the operation of this cordless telephone or cause noise during operation. Units
not containing coded access may be accessed by other radio communication systems. Cordless
telephones must not cause interference to any licensed radio service.
