• Do not put liquids, metals, or other foreign objects into au IC
card/microSD memory card slot of the product. Doing so may
result in a malfunction.
• Do not subject to strong impact, such as dropping, stomping
and throwing. Doing so might cause fault.
• Do not put the product directly on sand at a beach, etc. Sand
or other small particles might get inside the receiver/speaker,
the mouthpiece, the speaker, causing the volume to drop. If
sand gets inside this product's main unit, it might cause fault.
■ 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.
■ Organic EL (OLED) display
• Although lightning intensity of OLED can be decreased
partly when the same image has been displayed for a long
time, extreme continuous use is performed with "Brightness"
setting of "Display and wallpaper" set to be always bright, it is
not abnormal because that is the characteristic of OLED.
• Although the organic EL (OLED) display used on the product
is made using high-precision technology, some pixels (dots)
might be lit or out at all times. Or color may be changed or
unevenness of brightness may be shown if looked at from
different angles. Note that that is because of the structure of
OLED display, not a fault.
• Leaving the OLED exposed to the direct sunlight might cause
a fault. Take care when you place the product by the window
or outside.

■ 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 this product. If you do not use this 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 batteries and does not
pose any safety risks.
■ Charging equipment
• Do not wrap the power cord of the specified charging
equipment (sold separately) around the adapter. Also, do
not forcibly bend the plug of the charging equipment (sold
separately) or the connection between the connector and
power cord. Do not pull or place a heavy object on the charging
equipment (sold separately) code with unnecessary force.
