• BATTERIES AND CHARGERS

This phone is intended for use when supplied with power from the ACP-12U
and LCH-9 chargers. Other usage could invalidate any approval given to
this apparatus and might be dangerous.
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 will 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.
• 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 lifespan. 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 off.
Do not short-circuit the battery. Accidental short-circuiting can occur when
a metallic object, like a coin, a clip, or a pen causes a direct connection of
the + and - terminals of the battery, which are metal strips on the end of
the battery.
