Operation under water
● Placing stickers or sheets (e.g. protective films, peep prevention
sheets) on the display 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.
SIM card
● Do not forcibly remove or insert the SIM card. Be careful not to exert
excessive force when inserting the card into your product.
● You are responsible for any damage caused by inserting your SIM
card into some other IC card reader/writer, etc.
● Do not put stickers etc. on the SIM card.
● Do not insert the SIM card attached with a conversion adapter. Doing
so might cause a fault.
● Do not subject the SIM card to actions that can damage it (use in
high-temperature conditions, throwing in a fire, allowing metal
contacts to come in contact with foreign objects, subjecting to shock,
bending or pressing, wetting, etc.). Doing so might erase data or
cause a fault.
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. Also charge the battery after long
periods of disuse before using the product.
● Use in very hot, humid, 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 and charge the internal battery as much as possible at
room temperature.
● Using apps for a long time with the product being charged may
shorten the internal battery's service life.
