Installation
You must install and charge
the handset battery before
using the cordless handset.
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 (see page 10). 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 between one to 12 feet away from 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
base and the telephone wall jack (see the following page). 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.
