Safety precautions
46
■ Internal battery
● Use in very hot or cold environments, for
example, leaving the product in an
automobile with the windows closed in
summer, will cause the internal battery
capacity to drop and shorten the usable
time. This will also shorten the internal
battery's service life. Try to use the product,
as far as possible, at room temperature.
● Charge the battery before using the product
for the first time after purchase, or if you
have not used the product for a long time.
● The internal battery is a consumable item. If
the battery performance does not recover
(e.g. the usable time after each charge has
become extremely short), stop using the
product as the internal battery is at the end
of its service life. Failure to do so might
cause overheating, fire, rupture or leakage.
Since the battery is a built-in type, you must
bring your product to an au shop, etc. to
have it repaired at your expense. Also note
that you may be unable to use your product
for a certain period of time. The length of
service life varies depending on the usage
conditions, etc.
● The internal battery may swell up as it
approaches the end of its service life
depending on the usage conditions. This is
due to the properties of lithium polymer
batteries, and is not a problem in terms of
safety.
■ Charging equipment
● When not using the specified charging
equipment (sold separately), remove the
plug from the power outlet.
