1. Insert the supplied AC adapter’s

barrel plug into the

POWER 9V DC

jack on the back of the base.

2. Plug the adapter into a standard

AC outlet.

CHARGING THE
BATTERY

Before you connect the phone to the
phone line and use the phone for the
first time, or whenever you install a
new battery, make sure

RINGER OFF/

ON

on the handset is set to

OFF

, then

charge the battery for about 24 hours
by placing the handset on the cradle so
the CHARGE indicator on the base
lights.

The phone charges whenever the
handset is on the base. You can re-
charge the battery at any time, but you
must be sure to recharge it when the
handset sounds a beep every 7 sec-
onds.

Notes:

• If the CHARGE indicator on the

base does not light when you
place the handset on the cradle,

be sure the AC adapter is
securely connected to the base.

Also, check the charging contacts
on the handset and base. If the
contacts are dirty or tarnished,
gently clean them with a pencil
eraser.

• A full charge lasts about 168

hours if you leave the handset off
the base and do not make any
calls.

• About once a month, fully dis-

charge the battery. Otherwise, the
battery loses its ability to fully
recharge. To fully discharge the
battery, set

RINGER OFF/ON

on

the handset to

ON

and keep the

handset off the cradle until the
handset beeps every 7 seconds.
Then return the handset to the
cradle, set

RINGER OFF/ON

to

OFF,

and recharge the battery for

about 10 hours.

• When the battery cannot fully

recharge, replace it with a new
one. For the best performance,
you should replace the supplied
battery about once a year — more
often if it is used heavily. See
“Replacing the Battery’’ on
Page 21.
