Installation 

Digital Security System

Your cordless phone uses a digital security system to protect against false ringing, unauthorized 

access, and charges to your phone line.

INSTALLATION NOTE:  Some cordless telephones operate at frequencies that may cause 

or receive interference with nearby TVs, microwave ovens, and VCRs. To minimize or 

prevent such interference, the base of the cordless telephone should not be placed near 

or on top of a TV, microwave ovens, or VCR. If such interference continues, move the 

cordless telephone farther away from these appliances.
Certain other communications devices may also use the 2.4 GHz frequency for 

communication, and, if not properly set, these devices may interfere with each other 

and/or your new telephone. If you are concerned with interference, please refer 

to the owner’s manual for these devices on how to properly set channels to avoid 

interference. Typical devices that may use the 2.4 GHz frequency for communication 

include wireless audio/video senders, wireless computer networks, multi-handset 
cordless telephone systems, and some long-range cordless telephone systems.

Important Installation Guidelines

•  Avoid sources of noise and heat, such as motors, fluorescent lighting, microwave ovens, 

heating appliances and direct sunlight.

•   Avoid areas of excessive dust, moisture and low temperature.
•   Avoid other cordless telephones or personal computers.
•  Never install telephone wiring during a lightning storm.
•  Never install telephone jacks in wet locations unless the jack is specifically designed for wet 

locations.

•  Never touch non-insulated telephone wires or terminals, unless the telephone line has been 

disconnected at the network interface.

•  Use caution when installing or modifying telephone lines.

the telephone company may temporarily discontinue service immediately.
The telephone company may make changes in its communications facilities, equipment, operations 

or procedures where such action is required in the operation of its business. If these changes are 

expected to affect the use or performance of your telephone equipment, the telephone company will

the sum of the RENs of all devices connected to one line should not exceed 5. To be certain of the 

number of devices you may connect to your line as determined by the REN, you should contact your 

local telephone company.

REN Number is located on the cabinet bottom.
