Battery installation
Install a 9 V Alkaline (6LR61) battery
(sold separately) in the battery
compartment. It works as emergency
power during a power failure. The unit
will work as a standard telephone, so
that you can make or answer outside
calls with the handset. (You cannot use
the speakerphone, intercom, etc.)
1
Open the battery cover by sliding in
the direction of arrow (

out the battery snap (

).
2
Match the polarity and snap the
battery to the battery snap as shown.
3
Place the battery into the battery
compartment.

Dress the battery snap wire, and
close the battery cover.
Note:

Please refer to “Battery” on page 7 for
correct battery usage.
L
When 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.
L
The Manganese (6F22) battery can be
used but operating time when using it
will be dramatically shortened.
L
It is recommended that the battery is
replaced annually.
L
It is recommended that the battery is
replaced after a power outage.
L
The battery operating time may
depend on usage conditions, ambient
temperature, and battery quality.
L
During 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.
L
When storing or disposing of the
battery, please cover the positive (
S
)
and negative (
T
) terminals with tape.
Battery replacement
Disconnect the telephone line cord(s)
before opening the battery cover.
Note:
