Thoroughly read the precautions described in "Notes on Waterproof
and Dustproof Properties" for proper use. Failure to observe the
precautions may cause ingress of liquid or dust, resulting in
overheating, ignition, electric shock, injury or a fault.
Note that proper operations of the product are not guaranteed in all
circumstances. Faults determined, after an inspection, to be caused
by mishandling by the customer such as using the product without
observing the precautions described in "Notes on Waterproof and
Dustproof Properties" are not covered by the warranty.
■
Waterproof and Dustproof Properties of the
Product
The product has a protection rating (JIS C 0920) for waterproof
property equivalent to IPX5
*1
and IPX8
*2
, as well as dustproof property
equivalent to IP5X
*3
on the condition that the au Nano IC Card 04/
microSD memory card cover is securely closed (based on the
experiments by the Company).
*1 IPX5 means that the cell phone continues to function as a phone after
being subjected to a water jet (approximately 12.5 liters/min) discharged
from a water pouring nozzle (inner diameter: 6.3 mm), from all directions
and approximately 3 meters away from the cell phone for at least 3
minutes.
*2 IPX8 means that the cell phone continues to function as a phone after
being gently lowered into a tank filled with still tap water (at room
temperature) to the depth of 1.5 meter, immersed at the bottom for
approximately 30 minutes and then taken out of the tank.
*3 IP5X means that the cell phone continues to function as a phone and its
safety is maintained after being agitated in an apparatus with dust
(diameter: 75
μ
m or less) for 8 hours. (This does not guarantee complete
prevention of dust ingress.)
■
Examples of Waterproof and Dustproof Properties of
the Product
•
The product can be used at the poolside. However, do not wet it with
water other than tap water such as pool water or submerge it in pool
water.
•
The product can be washed with a low-pressure flow of tap water (up
to 6 liters/min) at room temperature (5
°
C to 35
°
C).
■
Handling the Product
•
Close the au Nano IC Card 04/microSD memory card cover securely.
The waterproof and dustproof properties are ensured when it is
securely closed. Even a small object (hair, sand, tiny fiber, etc.)
trapped between contact surfaces may cause ingress of liquid or
dust.
•
If liquid such as water is splashed onto the product with the au Nano
IC Card 04/microSD memory card cover opened, the liquid may
enter it, causing electric shock or a fault. Discontinue use and turn off
the power and then contact your local au shop or Keitai Guarantee
Service Center.
•
When the product is wet, wipe it with a dry, clean cloth.
•
When your hand or the product is wet or a foreign object is adhered
to it, never open/close the au Nano IC Card 04/microSD memory
card cover.
•
The product is only resistant to fresh/tap water at room temperature
(5
°
C to 35
°
C). If you let the product get wet with or submerged in
liquids other than fresh/tap water at room temperature, discontinue
use and wash it with fresh/tap water at room temperature.
•
Do not use the earphone/microphone jack or external connection
jack when it is wet or sand or dust is adhered to it. Doing so may
impair the waterproof and dustproof properties or cause electric
shock, short circuit, etc. resulting in fire, burns, or a fault.

Dustproof Property of the Product
•
The dustproof property of the product only guarantees a protection
rating equivalent to IP5X and does not guarantee its performance
under other circumstances such as when the product is directly
placed on sand at a beach, etc.
•
If dust is adhered to the product, immediately wash it away with
water or otherwise clear it completely before use.
•
Any dust adhered to the product might cause a fault such as
malfunction of the sliding part of the camera slide cover.
■
Notes on Using the Product
•
Do not let the product get wet with or submerged in liquids other
than tap water (seawater, pool water, spa water, soapy water,
detergent solutions, bubble baths, juice, condiments, etc.). In
addition, do not use the product in places subject to pet urine.
If the product gets exposed to such liquids, wash away with tap
water immediately.
•
Wash away salt water, seawater, drink, condiments, food, mud, soil
or any other foreign object immediately.
If allowed to dry, it will be difficult to remove the residue and may
cause scratching or a fault.
•
Wash away sand, mud, etc. completely; any residue may scratch or
damage the product, or otherwise cause a fault.
•
Do not immerse the product in a bathtub or swimming pool. In
addition, do not use it under water (including key operations).
•
The product is not designed to resist water pressure. Do not expose
the product to a high-pressure flow of tap water, shower, etc. (6
liters/min or more) or submerge it under water.
•
Extreme temperature changes may cause condensation, resulting in
a fault. Wait until the product reaches room temperature before you
bring it from a cold place into a warm place. If condensation occurs,
leave the product in room temperature until the condensation
evaporates.
•
Do not expose the product to hot water or hot air from a hair dryer,
etc. or use it in saunas. The product is not heat resistant.
•
Ingress of water into the earpiece (receiver)/speaker or mouthpiece
(microphone) may lower the volume temporarily. Drain water and dry
the product well before use.
•
The product does not float on water.
•
Do not use the product in heavy rain.
•
Do not leave the product wet. Doing so in cold places might cause
the liquid/moisture to freeze, resulting in a fault.
•
Do not place the product directly on sand at a beach, sandbox, etc.
or on mud. Sand may enter the earpiece (receiver)/speaker, etc.,
causing the volume to drop. Letting sand or other small particles
enter the product might cause overheating or a fault.
•
Letting sand or other small particles enter the sliding part of the
camera slide cover might cause excessive friction or noise when the
cover is opened/closed.
•
If the au Nano IC Card 04/microSD memory card cover is worn or
damaged, the waterproof and dustproof properties cannot be
maintained.
•
Do not use or store the product in humid places such as a bathroom
or kitchen for an extended period.
•
The product is not resistant to impact. Do not drop or subject to
impact. In addition, do not poke the earpiece (receiver)/speaker,
mouthpiece (microphone), air vent, etc. with a sharp object. Doing so
might damage or deform the product, resulting in impairment of the
waterproof and dustproof properties.
■
Maintaining the Waterproof and Dustproof
Properties
■
Rubber Seal
The rubber seal on the au Nano IC Card 04/microSD memory card
cover is important to maintain the waterproof and dustproof properties.
Observe the following:
•
Do not remove or scratch it.
•
When closing the au Nano IC Card 04/microSD memory card cover,
do not get the rubber seal caught. In addition, do not insert a sharp
object into gaps around the au Nano IC Card 04/microSD memory
card cover, the earphone/microphone jack or external connection
jack.
Doing so may damage the rubber seal, causing ingress of liquid or
dust.
•
To maintain the waterproof and dustproof properties, it is
recommended that you replace the parts once every two years
regardless of their condition (paid service). For information on part
replacement, contact your local au shop.
