Battery and Signal

Your phone is powered by a rechargeable battery.  Use only batteries
approved by the phone manufacturer and recharge your battery only with the
chargers approved by the manufacturer.  See "Important Battery
Information" below.

STOP:  A new battery must be fully charged before being used for the first
       time.  A new battery's full performance is achieved only after two
       or three complete charge and discharge cycles!

To Install the Battery

Place the battery on the back of the phone with the contacts facing
forward, and slide it up until it clicks into place.

To Remove the Battery

Press down on the catch at the top of the battery and slide it back, then
lift it off the phone.

Switch off the power before removing the battery.

To Charge the Battery

Plug the charger into a standard AC wall outlet then connect the connector
to the bottom of your phone.

When charging starts the battery segments scroll and the phone beeps once.

You can use the phone during the charging, but the charging will be
reduced for the duration of the call.  Note that if the battery is
completely empty and you are using the Standard Travel Charger (ACH-8U),
you can't use the phone until it has enough charge to operate.

After the segments of the battery indicator bar stop scrolling and the bar
is entirely displayed, the battery is charged.

If the battery is too hot or cold, the charging may be interrupted.

Charging Times

The battery charging times below are approximate.

                                   Standard Charger        Rapid Charger
 Battery                              (ACH-8U)                (ACH-6U)

Slim 600 mAh NiMH (BMT-1L)             5 hours               60 minutes

Extended 800 mAh NiCd (BKL-2S)         6 hours               90 minutes

Talk and Standby Times

Battery operation times depend greatly on how you use the batteries, as
well as on the coverage of the network and network parameters set by the
cellular service provider.

Battery                      Talk Time        Standby Time

Slim 600 mAh NiMH        1 hour 15 minutes      15 hours
(BMT-1L)

Extended 800 mAh NiCd    1 hour 40 minutes      21 hours
(BKL-2S)

To Discharge the Battery

A battery lasts longer and performs better if you fully discharge it from
time to time!

To discharge the battery, either leave your phone switched on until it
turns itself off or use the battery discharge feature of any approved
accessory available for your phone.

Note:  Do not attempt to discharge the battery by any other means.

Battery Low

You get this message and a warning tone when the battery charge is low and
only a few minutes of talk time remain.

When the Battery charge is too low for the phone to operate, RECHARGE
BATTERY is displayed and a warning tone is given.  After about 10 seconds,
the phone automatically switches itself off.

Note:  If Silent Service has been selected, no audible warning tones are
       given.

Charge the Battery as described earlier in this section.

Important Battery Information

Use only batteries and chargers approved by the phone manufacturer.

When a charger is not in use, disconnect it from the power source.  Do not
leave the battery connected to a charger for longer than a week;
overcharging may shorten its life.

If left unused, a fully charged battery will discharge itself in about a
week at room temperature.

Never use any charger or battery that is damaged or worn out.

Use the battery only for its intended purpose.

Do not short circuit the battery.  Accidental short circuiting can occur
when a metallic object (e.g., coin, clip, or pen) causes direct connection
of the + and - terminals of the battery (metal strips on the back of the
battery), for example when you carry a spare battery in your pocket or
purse.  Short circuiting the terminal may damage the battery or the
connecting object.

Leaving the battery in hot or cold places, such as in a closed car in
summer or winter conditions, reduces the capacity and life time of the
battery.  Always try to keep the battery between 59 and 77 degrees F (15
and 25 degrees C).  A phone with a hot or cold battery may temporarily not
work (or charge) even if the battery is fully charged.  NiMH battery
performance is particularly limited in temperatures below 14 degrees F
(-10 degrees C).

Temperature extremes affect the ability of your battery to charge.  It may
require cooling or warming first.

When the battery is not in use, store it uncharged in a cool, dark and dry
place.

The battery is a sealed unit with no serviceable parts.  Do not attempt to
open the case.

It is recommended that you allow your battery to fully discharge before
you recharge it.

The battery can be charged and discharged hundreds of times but it will
eventually wear out.  When the operating time is noticeably shorter than
normal, it is time to buy a new battery.

Do not dispose of a battery in a fire!

Dispose of used batteries in accordance with local regulations.  Recycle!

NiCd NiMH  Nickel Cadmium and Nickel Metal Hydride batteries must be
           recycled or disposed of properly.  Must not be disposed of in
           municipal waste.

Signal Strength Indication

A cellular phone sends and receives radio signals.  As with all radio
equipment, the quality of radio reception depends on the strength of the
radio signal in the area where you are operating your phone.

The strength of the cellular signal is shown by the vertical bar on the
left-hand side of the display.  The higher the bar, the stronger the
signal is where you are operating your phone.

When NO SVC is displayed, the phone is outside of the cellular service
area and calls cannot be made or received.

If the signal is poor and you are using the phone in a building, you may
get better reception near a window.
