TECHNICAL
INFORMATION
This cordless phone 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: Electric pulse noise is present in
most homes at one time or another. This
noise is most intense during electrical
storms. Certain kinds of electric
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 frequencies are
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.
Interference: Some electronic devices
operate in and/or generate interference
near the operating frequencies of your
cordless telephone. While several
protection circuits are used to prevent
unwanted signals, there may be periods
when these unwanted signals cause
interference. If interference occurs
frequently, it can be minimized or
eliminated by lowering the height of
your base antenna or by relocating the
base unit. You can check for
interference before selecting the final
base unit location by plugging in the
phone.
