● 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.
● 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.
● The internal battery is a consumable item. If the performance of the
internal battery does not recover and deteriorates (e.g. the usable
time after each charge has become extremely short or the internal
battery swells), 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 Style/au shop etc. and charges will be incurred for repair.
Please understand this in advance. Battery life varies depending on
usage conditions and other factors.
● 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
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.
Quick Switch Adapter (Sample)
● Fully insert the Quick Switch Adapter (sample) all the way to the
product. Not doing so might cause overheating, ignition, electric
shock, fires or injury. Also, insert/remove it in parallel to the external
connection jack. Not doing so might cause a fault or operation failure.
