Safety Precautions
■ Touch panel
■ Internal battery
● Use your finger or the stylus pen to operate the touch panel.
Do not use ballpoint pens, pencils or other sharp-pointed
objects. Using such objects does not only hinder correct
operation of the touch panel, but also might cause
scratching or damage to the display.
● Do not put an object such as the stylus pen on the touch
panel. The touch panel might respond to it, causing
unexpected operations of the 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.
● Operating the touch panel with fingernails might result in split
nails or jammed fingers.
● If the display surface is dirty or wet with sweat or water, it
may not function correctly. In such case, wipe the display
surface with a dry, soft cloth.
● When carrying the product in your 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.
● Use 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 will also shorten the
internal battery’s service life. Try to use the internal battery as
much as possible at room temperature.
● The internal battery gradually discharges after charging even
if the product is not used. The internal battery may discharge
completely after long time no use. Charge before using the
product.
● Because the internal battery performance or service life will
become low, do not store the product in the following
conditions.
• Battery level is full (soon after charging is complete)
• Battery level is empty (to the extent that the product is not
powered on)
• In extremely hot or humid conditions
● 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 performance
of the internal battery does not recover after charge, the
internal battery is at the end of service life, so stop using it.
Since the battery is built-in type, the product will be kept at
an au shop etc. and charges will be incurred for repair. Also,
you may not use the product in certain period of time. Note
that the length of service life varies depending on the usage
condition, etc.
● Internal batteries sometimes swell up as they approach the
end of their service life depending on the usage condition.
This is due to the properties of lithium-ion batteries, and is
not a problem in terms of safety.
