Getting started
Installation preparation
You must install the power 
adapter before using the 
telephone.
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 5 and 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 a protective sticker covering the telephone 
base display - remove it before use.
