Security 

 
65,536 Combination Security Coding 

The unit has a digital coding security system to prevent unauthorized use of your telephone 
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.
