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.
