line by other cordless phones nearby. The unit has 65,536 possible security code
combinations.
Out of Range Detection
The unit is equipped with an Out-of-Range detection system. If you have the handset too far
away from the base unit during a call, the handset may lose its link with the base unit. When
this happens, the handset emits a beeping sound every second to warn you that the
background noise level is too high for proper communication between the handset and the
base unit. When you hear this sound, you should move closer to the base unit to reduce the
noise level. Otherwise, the call will automatically cut off.
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 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 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.
