Installation
Install the telephone base close to a telephone jack and a power
outlet not controlled by a wall switch. The telephone base can be
placed on a flat surface or vertically mounted on the wall (see page
11). For optimum range and better reception, place the telephone
base in a central and open location.
If you subscribe to high-speed Internet service (DSL - digital subscriber
line) through your telephone line, you must install a DSL filter between
the telephone line cord and the telephone wall jack (see page 6). The
filter prevents noise and caller ID problems caused by DSL interference.
Please contact your DSL service provider for more information about
DSL filters.
Your product may be shipped with protective stickers covering the
handset and telephone base displays - remove them before use.
For customer service or product information, visit our website at
www.telephones.att.com or call 1 [phone]. In
Canada, dial 1 [phone].
Avoid placing the telephone base and charger too close to:
Communication devices such as television sets, VCRs, 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 a washing
machine or workbench.
