Installation preparation

If you subscribe to high speed Internet service (DSL – digital subscriber line) through your telephone line, you must install a DSL filter between each telephone line cord and telephone wall jack (pages 3 and 4). 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 a protective sticker covering the telephone base display – remove it before use. For customer service or product information, visit our website at www.telephones.att.com or call 1 (800) 222-3111. In Canada, dial 1 (866) 288-4268.

Avoid placing the telephone base too close to:

  • Communication devices such as television sets, VCRs, or 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 work bench.

  1. I need to know the ringer equivalent of AT&T ML17929 2-Line Corded Telephone. Examples are: “REN .3B” or worse “REN 1.1B” – usually molded onto the back of phone in microscopic letters. I am trying to find a 2 line phone with REN 0.3B or less. Why don’t these manuals list the REN?
