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
