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 4 and 5). 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.
