Technical Information
This cordless telephone uses radio frequencies to allow mobility. There are certain
difficulties in using radio frequencies with a cordless telephone. While
normal, the following could affect 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 occasion-
ally 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, location of the BASE UNIT can affect operating
range. Try several locations in your home or business 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 tel-
ephone 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
frequently, it can be minimized or eliminated by lowering the height of your BASE UNIT
ANTENNA or by relocating the BASE UNIT. You can check for interference before
selecting the final BASE UNIT location by plugging in the phone.
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 interfer-
ence to any licensed radio service.
