Notes…on…Usage
…
■ Touch…Panel
• Do not put stickers or sheets (e.g. commercially
available protective films, peep prevention sheets)
on the display. Doing so might hinder correct
operation of the touch panel.
• When carrying the product in your pocket or bag,
take care not to put the touch panel close to metals
or other conductive materials, as it might cause
false operation of the touch panel.
…
■ Internal…battery
(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. If you
have not used the product for a long
time, you should charge the battery.
• At extremely high or low temperatures, such as if you
leave the product in a closed car during summer, the
capacity of the internal battery decreases and so will
the amount of time it can be used decreases. This
also decreases the lifespan of the battery. Use the
product at room temperature whenever possible.
• After charging the battery, it gradually discharges,
even if you do not use the product. If you do not
use the product for a long time, you should charge
the battery as the internal battery may have
discharged.
• The internal battery is a consumable item. If the
performance of the internal battery does not recover
(e.g. the usable time after each charge has become
extremely short), stop using the battery as it is at
the end of its service life. As the battery is built-
in, you can have it replaced at an au shop for a fee.
Note that you will not be able to use the product for
a certain period of time. The battery lifespan varies
depending on how the product is used.
• Depending on the use condition, the internal battery
may be inflated as it comes close to the end of its
service life. This is due to the properties of lithium-
ion battery and does not pose any safety risks.
