calls with the handset. (You cannot use
the speakerphone, intercom, etc.)

the direction of arrow (1), and take
out the battery snap (2).

battery to the battery snap as shown.

LPlease refer to “Battery” on page 7 for
correct battery usage.
LWhen the display shows “LOW BATT”
with a 9 V battery in the unit, the
battery needs to be changed
immediately. If the battery level is too
low, all LEDs might light up or flash
and the unit is not guaranteed to
perform as normal during a power
failure. Replacing with a fresh battery
will restore normal function.
LThe Manganese (6F22) battery can be
used but operating time when using it
will be dramatically shortened.
LIt is recommended that the battery is
replaced annually.
LIt is recommended that the battery is
replaced after a power outage.
LThe battery operating time may
depend on usage conditions, ambient
temperature, and battery quality.
LDuring a power failure the battery will
retain the clock memory (see “Date
and time” on page 24) and the redial
memory (see “Making a call using the
redial list” on page 25). If you do not
install the battery, the data in memory
will be lost during a power failure.
LWhen storing or disposing of the
battery, please cover the positive (S)
and negative (T) terminals with tape.
