DECT 6.0 cordless telephone
with caller ID/call waiting
Installation
Install the telephone base close to a telephone jack and a power outlet not
controlled by a wall switch. For optimum range and better reception, place
the telephone base in a central and open location.
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 (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.

Battery installation & charging
Install the battery as shown on the next page. Once you have installed the
battery, the screen indicates the battery status (see table below). If necessary,
place the handset in the telephone base to charge the battery. For best
performance, keep the handset in the charger when not in use. The battery is
fully charged after 16 hours of continuous charging. See the table on the
Technical specifications page of the user's manual for battery
operating times.
If the screen is blank, you need to charge the handset without interruption for
at least 10 minutes to give the handset enough charge to use the telephone
for a short time. The screen shows LOW BATTERY and the backlight is off until
you have charged the battery without interruption for at least one hour. The
following table summarizes the battery charge indicators and actions to take.
