Inserting the backup batteries

Your recorded messages and settings are stored in the phone's memory.

They will be lost if a power interruption occurs (such as if the AC plug is
accidentally disconnected, or if there is a temporary power failure).

Inserting four size AAA batteries lets you back up the memory contents in
case of a power interruption.

1.  Slide open the backup battery compartment cover.

2.  Insert the four size AAA (R03) batteries (supplied). Make sure the (+)
    and (-) on the batteries match the markings in the backup battery
    compartment.

3.  Slide the cover back until it snaps into place.

4.  Connect the base unit to an AC outlet.

If the base unit is not connected to an AC outlet while the backup
batteries are inserted, the batteries will soon be consumed.  Be sure to
connect the base unit to an AC outlet as soon as possible.

Replace the backup batteries about once a year.  When replacing the
batteries, make sure the phone is plugged into an AC outlet, or all your
messages and settings will be lost.

    Backup duration - The supplied (manganese) batteries provide backup
    power if an AC power failure occurs.  The backup duration is
    approximately 7 hours.

    When the backup batteries become weak - The POWER lamp on the base unit
    blinks.  The lamp also blinks when no backup batteries are inserted
    while the base unit is connected to an AC outlet.

Preparing the battery packs for the cordless handset

Charging the battery packs

Charge one of the supplied two battery packs for about 10 hours and insert
it in the cordless handset.  Charge the other one so you can exchange with
the first one when the latter becomes discharged.  You may leave a battery
pack in the charging compartment of the base unit even if it is completely
charged.

1.  Insert one of the supplied battery packs completely into the charging
    compartment.  The CHARGE lamp on the base unit lights.

    If a battery pack is brand new or completely discharged, it may
    take 10 minutes or more before the CHARGE lamp lights up.

2.  Charge the battery pack for about 10 hours.  When the charging is
    completed, the CHARGE lamp will go off.

    NOTE:  Make sure that the base unit is connected to a continuous
           power supply.

If the battery pack is charged for less than 10 hours due to a power
interruption, the battery will not be fully charged. It will, therefore, be
effective for a shorter period of time than a fully charged battery pack.

Installing a charged battery pack

After you have fully charged a battery pack in the base unit, install it in
the cordless handset as follows.

1.  Slide open the battery compartment lid.

    If the lid comes off, you can replace it easily by snapping it into
    place.

2.  Remove the charged battery pack from the base unit and insert it into
    the handset’s battery compartment.  Press the lever on the base unit’s
    charging compartment to release the battery pack.

3.  Replace the battery compartment lid.

NOTES ON CHARGING

    The battery pack supplied uses a unique lead acid battery which works
    best when recharged often.  Unlike nickel-cadmium batteries, you do not
    need to wait until the battery becomes weak to recharge.

    Avoid leaving the handset without charging the battery for an extended
    period of time so that the battery runs down completely.  This can
    shorten the battery’s life.   If this happens, recharge the battery.
    You may need to charge the battery several times before it is recharged
    to its full capacity.

    When charging a battery pack which is completely discharged, the
    battery lamps may not light up for a while (10 minutes or less).  There
    is nothing wrong with your telephone.  Continue charging.

Battery duration

A fully charged battery pack in the cordless handset will last
approximately:

    10 hours in continuous talk mode
    30 days (1 month) in RING ON mode
    2 months in BATT SAVE mode

    The battery packs will gradually discharge over a long period of time
    even if not in use.

    When not using the handset for an extended period of time, take the
    battery out of the handset and store it after charging for over 10
    hours.

To determine the remaining battery power - Press TALK.  The battery lamps
will give you the following information:

Battery lamps           Amount of battery power

(3 lamps lighted)       Full power

(2 lamps lighted)       Some power (Exchange the battery as soon as
                        possible).

(1 lamp lighted)        Little power (Exchange the battery immediately).

(No lamps lighted)      No power (Cordless handset cannot operate any more
                        without charging the battery).

If the battery becomes weak during a phone call 

    The phone will beep every three seconds.  Within one minute you must
    exchange the battery pack; otherwise the call will be disconnected.

Exchange the battery during phone call

1.  Press HOLD to put the call on hold.  The TALK lamp flashes.

2.  Exchange the battery in the cordless handset with a fully charged one
    in the base unit.

3.  Press TALK.  The TALK lamp flashes again.

4.  Press HOLD to resume the conversation.

When to replace the battery pack

    The battery can be recharged many, many times.  However, if the battery
    lasts only for a few minutes even after 10 hours of charging, it needs
    replacement.

    To purchase a replacement battery, please visit your local Sony
    authorized dealer or service center.

Be sure to use only Sony BP-T40 batteries.

    If a power interruption lasts for more than several days, or when
    unplugging the base unit from the AC outlet, remove the battery pack
    from the base unit and store it away.
