18. Reference information
• Batteries, chargers, and accessories
This section provides information about the phone’s batteries, accessories,
and chargers. Be aware that the information in this section is subject to
change as the batteries, chargers, and accessories change.
This phone is intended for use when supplied with power from an ACP-7U,
an ACP-8U, or an LCH-9 charger.
Warning! When you purchase batteries, chargers, and accessories
for your phone, use only batteries, chargers, and accessories that
have received approval from the phone’s manufacturer. The use
of any other type of phone-related hardware may invalidate any approval
or warranty applying to the phone, and could also be dangerous. For
availability of approved batteries, chargers, and accessories, check with
your dealer.
Note: For information on how to charge and recharge your battery, refer
to “Charge the battery” on page 10.
When the battery is fully charged, the indicator will tell you that
the battery is fully charged.
When you are not using a charger, disconnect it from the power source.
Do not leave the battery connected to a charger for more than a week,
since overcharging could shorten its life span. If left unused, a fully-
charged battery will discharge itself over time.
Temperature extremes can affect the ability of your battery to charge.
Therefore, allow it to cool down or warm up before trying to charge it.
When the battery is running out of power and your phone only has a few
minutes of talk time remaining, a warning tone sounds and the
Battery
low message appears briefly. When no more talk time is left, a warning
tone is sounded and the phone switches itself off.
