Installation preparation

Make sure to install four
AA alkaline batteries
(not included) before
using the telephone.
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 line cord and the telephone wall jack.
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
handset or telephone base display - remove it before use.
