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
