■ Notes about the rechargeable battery
● A rechargeable lithium-ion battery is
the only kind that can be used.
Even if the battery supplied with the
unit is not used, you should charge it at
least once every three months because
of the special quality of this battery.
● The rechargeable battery can be
charged approximately 300 times.
● Do not use any battery other than that
specified. Use of other batteries may
cause malfunctions.
● When the operating time is reduced to
about half the normal amount of time,
even after a full charge is performed,
replace the battery with a new one.
● When charging or when using the re-
chargeable battery, use it within an am-
bient temperature range of 41°F - 95°F
(5°C - 35°C ).
● If the rechargeable battery is used in a
cold environment, the operating time
will decrease.
Since the rechargeable battery is
vulnerable to damage, please note the
following.
● Do not carry the battery in your pocket
or in a bag together with metal objects
(keys, coins, jewelry, etc.).
The battery may short out and generate
significant amounts of heat.
● Do not short-circuit the terminals as
they will become very hot and will dam-
age the battery.
● Do not dip the battery in water, do not
dispose of it in a fire, and do not take it
apart.
To avoid damaging the battery and
shortening its service life, please note
the following.
● Do not drop or subject the battery to
shock.
● Do not insert objects (metal etc.) into
the battery compartment of this product
or into the rechargeable battery. Do not

geable terminals are dirty, the opera-
ting time may be shortened or it may
not be possible to charge the battery.
