Installation and setup
Choose a central location close to a telephone jack and a power outlet not
connected to a wall switch. The telephone base can be placed on a flat sur-
face 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, tel-
evision 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 temperature.
• Mechanical vibration or shock such as on top of the washing machine or
work bench.
