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 1.9 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 1.9 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.
