• Charge the battery only at temperatures within the range of

10°C to 30°C (50°F to 86°F) (temperatures that are comfort-
able for people). At lower temperatures it becomes more
difficult to charge the battery and the battery deteriorates. It is
not possible to sufficiently charge the battery at high tempera-
tures.

• The battery may become hot during charging or during use,

but this is not a sign of malfunctioning.

• It may take more time to fully charge a hot battery.

• The battery has a certain life expectancy. The battery is

consumed as time elapses even if the battery is not used. A
battery that has been used for about a year may give you less
operating time depending on the conditions under which it
was stored. If a battery that has been charged correctly
operates for a much shorter time than usual, it has reached
the end of its life and must be replaced with a new battery.

• When the battery is at a low temperature (lower than 10°C

(50°F)) in winter, the operating time may be very short. The
battery undergoes an internal chemical reaction in order to
generate electricity. When the temperature outside is lower,
the chemical reaction becomes less vigorous and operating
time becomes shorter.

• Turn off the power supply frequently when not in use in order to give the battery longer life.

• The battery is consumed as time elapses even if the battery is

not used. To prevent consumption;
(1) If the battery will not be used for a long time, use the

product to run down what is left of the battery charge and
set “Battery charge” to “off” in the menu screen. (Refer to
page 29.)

(2) Make sure to use the battery at least once every six

months.

• The battery used in the product is a lithium-ion battery. Even if

the battery is charged and stored, the amount of charge in the
battery will drop.

• Make sure to charge the battery until the charge indicator of

the product goes off (fully charged). The operating time is
shortened when using a battery which has not been fully
charged. (For a detailed description of how to charge the
battery, refer to page 15.)
