Safety Precautions
● When you put the product in your pocket or bag, take care so that the display 
does not come in contact with metal objects or other hard objects, as it might 
cause scratching or damage. Also, be careful not to scratch or damage the 
display by using a strap whose metal or other hard part comes in contact with 
the display.
● When suddenly brought into a warm place from a cold place, or when in a 
humid location, or when used where temperature suddenly changes (e.g. 
near the air discharge port of an air conditioner), water drops (i.e. 
condensation) sometimes are formed inside the product. Note that when used 
under conditions such as this, humidity might cause corrosion or a fault.
● When wiping the display, wipe with a soft, dry cloth. Use of a moistened cloth, 
glass cleaner or other similar liquid might cause a fault.
● When connecting/disconnecting an external device to/from the external 
connection jack, make sure to insert/remove the connector of the external 
device straight to/from the external connection jack.
●
Note that applying unnecessary force with an external device connected to the 
external connection jack may cause damage.
● Do not discard the product together with regular trash. Please cooperate in 
the collection of the product when it is no longer needed to protect the 
environment and effectively use resources. Old products are collected at au 
shops and other places.
● Insert only a microSD memory card into the microSD memory card slot on the 
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, remove the battery pack 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 mouthpiece to make your voice inaudible to the other 
party, the other party can hear your voice.
● When using handsfree call, take care to keep the speaker at a safe distance 
from your ears, as the speaker volume may be too loud.
● Attach the battery cover securely. FeliCa function may not work properly. Also, 
if you deform the battery cover, forcefully press the inside of the battery cover 
on which the sheet is pasted or remove the sheet, FeliCa communications 
may be hindered.
● 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.
● Do not put a sticker, etc. on the proximity sensor. Doing so may cause the 
sensor to malfunction and make the display always turned off while receiving 
a call or during a call.
● If the display gets damaged, immediately stop use and contact an au shop or 
Secure cell phone support center. Keeping using it may cause injury.
● Do not apply unnecessary force to the sliding part when opening/closing the 
product or while using the product. Unnecessary force applied to the product 
by swinging it around or warping it might cause a fault or damage. 
● Putting a sticker, etc. on the display or a key may cause the key to be pressed 
continuously when the product is closed and that may result in malfunction 
such as key operation failure or shortened usage time. Also, doing so might 
damage the product.
● When answering a call while the TV antenna is pulled out or it is kept standing 
(e.g. while you are watching TV (1Seg)), take lots of care especially to the tip 
of the TV antenna so that it will not do any harm on surrounding people nor 
touch your own eye. When opening/closing the product, do not forget to store 
the TV antenna.
● If you put magnetized objects, metal straps, etc. close to the product, the 
speaker section sometimes emits sounds. This is not a fault.
● Note that if you forcefully pull external connection jack cover or apply 
excessive force on it, it may be damaged.
● When you put the product in your pocket or bag, do not forget to replace the 
TV antenna to its original position. Also, do not forcefully pull out or bend the 
TV antenna intentionally. Doing so may cause injury or damage.
● Bright places such as under the direct sunlight sometimes make it hard to see 
the display. This is not a fault.
