Discharging NiMH batteries

A NiMH battery lasts longer and performs better if you fully
discharge it from time to time. To discharge the battery,
leave your phone switched on until the battery is drained.
The phone will display several messages that the battery is
low and that you need to recharge it; just ignore them.
You can also use the battery discharge feature of any ap-
proved accessory available for your phone. Do not attempt to
discharge the battery by any means other than those just
described.

Important Battery Information

• The battery can be charged and discharged hundreds of
times but it will eventually wear out. When the operating
time (talk time and standby time) is noticeably shorter than
normal, it is time to buy a new battery.
• Use only batteries approved by the phone manufacturer and

See "Chargers
recharge your battery only with the chargers approved by
the manufacturer. When a charger is not in use, disconnect
it from the power source. Do not leave the battery con-
nected to a charger for longer than a week, since overcharg-
ing may shorten its life. If left unused a fully charged battery
will discharge itself over time.
• (NiMH batteries only) For optimal operation, discharge the
battery from time to time by leaving your phone switched on
until it turns itself off. You can also use the battery dis-
charge feature of any approved accessory available for your
phone. Do not attempt to discharge the battery by any other
means.
• Temperature extremes will affect the ability of your battery
to charge: allow it to cool down or warm up first.
• Use the battery only for its intended purpose.
• Never use any charger or battery which is damaged or worn
out.
• Do not short circuit the battery. Accidental short circuiting
can occur when a metallic object (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 cir-
cuiting the terminals may damage the battery or the con-
necting object.
• Leaving the battery in hot or cold places, such as in a closed
car in summer or winter conditions, will reduce the capacity
and lifetime of the battery. Always try to keep the battery
between 59º F and 77º F (15º C and 25º C). A phone with a
hot or cold battery may temporarily not work, even when the
battery is fully charged. NiMH batteries' performance is par-
ticularly limited in temperatures below 14º F (-10º C). Li-Ion
batteries' performance is particularly limited in tempera-
tures below 32º F (0º C).
• Do not dispose of batteries in a fire!
• Dispose of used batteries in accordance with any local regu-
lations.

Cool Features

All the features in your phone are cool. It's just that some are
cooler than others!
For example, did you know that you can lock the keys on
your phone to prevent accidental key presses and phone
calls? Or that you can call someone with the touch of a sin-
