To avoid any risk or danger, you
should observe the following precau-
tions.
• Use only Sanyo approved batteries,
AC adaptors and accessories
recommended for use with this
specific model. Using other batteries
or AC adaptors may cause damage
and invalidate your warranty.
• Batteries should be recycled or
disposed of correctly. They should
not be disposed of in municipal
waste.
• Do not dispose batteries in a fire.
• Do not charge or leave the batteries
in areas subject to high tempera-
tures (near a fire, heater etc.).
• Do not short-circuit the battery. Note
that short-circuiting could occur
accidentally if a metallic object (coin,
pen, jewellery, or similar) caused a
direct connection between the + and
- terminals of the battery.
• Never use an AC adaptor or battery
which is damaged or worn out.
• Do not attempt to disassemble the
battery.

If the phone is not going to be used for
an extended length of time, remove
the battery and store it in a dry place.

Leaving the battery in hot or cold
places, such as in a closed or open
car in the heat of summer or the cold
of winter will reduce the capacity and
life of the battery.
The battery should be stored at a
temperature of between 5°C and
