Notes on Usage
Li-ion00
(The internal battery of the
product is a lithium-ion battery.)
The internal battery is not
fully charged at the time of
purchase. Charge the battery
before using the product. Also
charge the battery before using
the product if you have not used
the product for a long time.
Using the product in very hot or cold
environments, for example, when left in
an automobile with the windows closed
in summer, will cause the internal battery
capacity to drop and shorten the available
battery usage time. This also shortens the
internal battery's service life. Try to use the
internal battery as far as possible at room
temperature.
After the internal battery is charged, battery
power decreases bit by bit even if the
product is not used. The internal battery may
be discharged if the product is not used for
a long time. We recommend to charge the
product before use.
Internal battery is a consumable item. If the
performance of an internal battery does not
recover (e.g. the usable time after each charge
has become extremely short), the internal
battery is at the end of service life, so stop
use. Since the battery is built-in, au Shop will
keep the product and charges will be incurred
for repair. You may not use the product for
a certain period. Please be forewarned. Note
that the length of service life varies depending
on the usage condition, etc.
