When removing the back cover, do not exert more than necessary
force. The battery pack might jump out, for example, and cause injury
or a fault.
Do not operate the product while driving an automobile or motorized
bicycle, riding a bicycle or walking. Doing so may compromise traffic
safety and cause an accident.
If charging is not completed after the specified charging time, stop
charging. Failure to do so might cause leakage of liquid, overheating,
rupture or fire.
Do not leave in places within the reach of small children. Small children
might swallow small parts, etc. by mistake and choke on them, or might
drop them by mistake and cause accidents or injury.
Be sure to read the following
CAUTION
cautions before use.
Do not store the product in places subject to direct sunlight (e.g. in
automobiles), places that get hot, places that get extremely cold, and
in humid or dusty places. Doing so might cause overheating, fire,
deformation or a fault.
Do not leave on unstable places such as rocky stands or tilting
surfaces especially while the vibration mode set. Dropping the product
may cause injury or damage. Also, pay sufficient attention to impact,
etc.
Do not cover or wrap the product with bedding, etc. while using or
charging the product. Doing so might cause fire, fault or injury.
Do not touch the product or specified charging (sold separately)
equipment for a long time while power is being supplied from an
external source. Doing so might cause low-temperature burns.
The product may become hot by prolonged use especially in
high-temperature environment. Be careful when using the product
touching your skin for a long time, as it might cause low-temperature
burns.
Do not use power outlets or wiring apparatus beyond its rating. Also,
exceeding rating, for example, by connecting multiple devices to a
single power strip might cause overheating and fire.
Do not use the product with the back cover removed.
Do not place near corrosive chemicals or in places where corrosive
gas is generated. Doing so might cause a fault or loss of internal data.
Do not leave or store with the back cover or battery pack removed
from the main unit. Doing so might allow dust or other foreign objects
to get inside and cause a fault.
Do not use if there is smoke, abnormal odor or noise, excessive
overheating, or other abnormalities. If an abnormality occurs,
disconnect the specified charging equipment (sold separately) from
the power outlet, make sure that the product is not overheating before
turning the power off or removing the battery off, and contact an au
shop or Secure cell phone support center. Also, if you have dropped
or damaged the product, do not continue to use it in that state, and
contact an au shop or Secure cell phone support center.
When using an earphone, etc. with the product, adjust the volume to
an appropriate level. Setting too loud a volume or using the earphone
continuously for a long period of time might adversely affect your
hearing. Also, raising the volume too high might prevent you from
hearing sounds around you, which might in turn lead to a traffic
accident at a railroad crossing or pedestrian crossing.
When adjusting the volume when using an earphone, etc. with the
product, raise the volume a little at a time. If you raise the volume too
much from the outset, sudden loud noise from the earphone, etc.
might adversely affect your ears.
When using the specified charging equipment (sold separately) or
external device, insert/remove the connector straight to/from the
terminal. Make sure the orientation of the connector is correct. Failure
to do so might cause damage or a fault.
