Getting started
Installation
Install the telephone base close to a telephone jack and a power outlet not 
controlled by a wall switch. The telephone base can be placed on a flat surface 
or vertically mounted on the wall (page 9). For optimum range and better 
reception, place the telephone base in a central and open location.
You may hear interference if your cellular phone is too close to the telephone 
base during a CELLULAR call. Make sure that your Bluetooth enabled cellular 
phone is within 15 feet of the telephone base in order to maintain a clear and 
consistent connection between your Bluetooth cell phone, telephone base and 
cell tower.
If you subscribe to high-speed Internet service (digital subscriber line - 
DSL) through your telephone line, you must install a DSL filter between the 
telephone line cord and the telephone wall jack (page 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 handset or 
telephone base display - remove it before use.
