Technical Information

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.
