● Do not insert a card other than microSD memory card into the
microSD memory card slot on this product.
● Do not exert excessive force when attaching/removing a microSD
memory card. Doing so might injure your hands or fingers.
● While writing/reading data to/from a microSD memory card, do not
subject the product to vibration or impact or turn off the power.
Doing so might cause loss of data or a fault.
● When hearing the other party's voice, make sure that the earpiece
is placed at the center of your ear. If the earpiece (audio output
port) is closed by the ear lobe, it may be hard to hear the voice.
● Even if you cover the microphone to make your voice inaudible to
the other party, the other party can hear your voice.
● Sound from speaker may be very loud when you use hands-free
calling. Keep it away from your ear when using it.
● Do not peel off the black sheet on the back cover (the back part
you can see when removing the back cover). Doing so might make
it impossible for FeliCa data recognition.
● Do not cover the light sensor with your finger or put a sticker on it.
Doing so may hinder the light sensor from detecting the ambient
brightness and functioning correctly.
● When you put a sticker, etc. on the proximity sensor, the sensor
will malfunction and indications on the display will turn off at all
times while receiving or making a call. In this case, note that you
may not be able to operate the product.

■ Touch■Panel
■
● Use your finger 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 stickers or sheets (e.g. commercially available
protective films, peep prevention sheets) on the display. Doing so
might cause improper reaction of touch panel.
● Do not operate the touch panel with fingernails. Doing so 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 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.
■ Built-in■battery
■
● Use in very hot or cold environments, for example, when left in
a car with the windows closed in summer, will cause the built-in
battery capacity to drop and shorten the available battery usage
time. This will also shorten the built-in battery service life. Try to
use the built-in as far as possible at room temperature.
● 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 built-in battery is a consumable item. If the performance does
not recover after charge, the built-in is at the end of its service
life, so stop using it. Because the battery is a built-in type, an au
shop will accept holding over and repair for a charge. Note that the
product may not be available for use for a certain period. Note that
the length of service life varies depending on the usage condition,
etc.
● built-in battery sometimes swell up as they approach the end of
their service life. This is due to the properties of lithium polymer
batteries, and is not a problem in terms of safety.
