Installation preparation
If you subscribe to high-speed Internet service (Digital Subscriber Line - DSL)
through your telephone lines, you must install a DSL filter between the
telephone base and the telephone wall jack. The filter will prevent 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 handset or
telephone base display - remove it before use.
