not use it under water. (including an operation for opening/closing 
the product and key operations.)
• The product is not designed to withstand high water pressure. Do 
not expose the product to a strong water flow with tap water, 
shower, etc. (6 liters/min or more) or submerge it under water.
• Do not leave the product in a humid place such as a bathroom for an 
extended period of time. Also, do not use the product in a bathroom 
for an extended period of time.
• To prevent condensation, wait until the product reaches room 
temperature before you bring it from a cold place into a bathroom 
etc. If condensation occurs, leave it in room temperature until the 
condensation is removed. 
• Do not get the product wet with hot water, use it in saunas or expose 
it to hot air from hair dryer etc.
• Do not place the product where it gets extremely hot or cold such as 
near a stove or in a refrigerator.
• Volumes may temporarily become lower due to water entering in the 
mouthpiece, earpiece, and speaker. Drain water and dry the 
product well before use.
• When water drops are attached on the touch panel or you perform 
touch operations with your hand wet, the product may not properly 
function.
• The product does not float on water.
• Do not use the product in heavy rain.
• Do not leave the product wet. Doing so may let the liquids freeze on 
the product in cold places or otherwise cause fault.
• Do not drop or otherwise subject the product to strong impact or jab 
the mouthpiece, earpiece, speaker, etc. with a cotton swab or any 
sharp object. Doing so may cause scratching, deformation, etc. on/
of the product, resulting in impairment of waterproof/dustproof 
property.
• Do not place the product directly on sand at a sandbox, beach, etc. 
or on mud. Grains of sand may get into the earpiece, speaker, etc., 
causing the volume to drop.
• Letting grains of sand etc. get into the opening/closing part of the 
main unit may cause the operations for opening/closing the main 
unit to become less tactile or cause unusual sounds.
• Packaged items (battery pack and desktop holder) or optional 
accessories are not waterproof/dustproof. When you watch 1Seg 
etc. with the product set on the desktop holder among packaged

as a bathroom, shower room, kitchen and lavatory even if the 
specified AC adapter (sold separately) is not connected to the 
desktop holder.
• If the battery cover or external connection jack cover degrades or is 
damaged, the waterproof and dustproof properties cannot be 
maintained. In such case, contact an au shop near you or Secure 
cell phone support center.
■ Maintaining the Waterproof and Dustproof 
Properties
■ Rubber seals
The rubber seals on the external connection jack cover and battery 
cover are important to maintain the waterproof property. Be sure to 
observe the following items.
• Do not remove or scratch them.
• When closing the external connection jack cover and battery cover, 
do not get the rubber seals caught. Also, do not insert sharp objects 
into gaps around the external connection jack cover and battery 
cover.
Doing so may damage the rubber seals and cause intrusion of water 
or dust.
• It is recommended to replace the parts for maintaining the 
waterproof and dustproof properties (pay service) once every two 
years regardless of whether any abnormality is present. For 
information on part replacement, contact an au shop near you or 
Secure cell phone support center.
