Technical information
This cordless telephone uses radio frequencies to allow mobility. There are certain dif-
culties 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, uorescent 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 the system.
Range
Because frequency is used, the location of the base unit can affect the operating range.
Try several locations in your home or ofce 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. 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.
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.
