Telephone base installation

Choose a central location close to a telephone jack and an electrical outlet not connected 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, 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.
