Getting started
Choose a location for your telephone
Choose a central location close to a telephone jack and a power outlet not con-
nected to a wall switch. The telephone base can be placed on a flat surface or 
mounted on a standard wall plate. For optimum range and better reception, place 
the telephone base in a high and open location.
Avoid placing the telephone base too close to:
• Communication devices such as: personal computers, computer routers, 
television sets, VCRs, wireless routers (wireless broadband, wi-fi, or 802.11) 
or other cordless telephones.
• Excessive heat sources.
• Noise sources such as a window with traffic outside, motors, microwave 
ovens, refrigerators, or fluorescent lighting.
• Excessive dust sources such as a workshop or garage.
• Excessive moisture.
• Extremely low temperatures.
• Mechanical vibration or shock such as on top of the washing machine or 
work bench.
