Rubber seals
The rubber seals around the external connection jack cover and on the main unit
when the back cover is removed are important to maintaining the waterproof
property. Do not damage or remove the rubber seals.
When closing the external connection jack cover or back cover, take care not to
get the rubber seals caught. Forcibly closing the cover with the rubber seals
caught may damage them resulting in loss of waterproof property. Just a small
particle (a hair, grain of sand, etc.) on the seals can cause water leak.
If any liquid other than plain water (e.g. alcohol) gets on the rubber seals, it may
cause deterioration in durability.
Do not insert sharp objects into gaps around the external connection jack cover
and back cover. Doing so might damage or deform the product or damage the
rubber seals, causing water leak.
It is recommended to replace the parts for maintaining waterproof property once
every 2 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.
Charging
Never charge the battery if the product is wet.
The supplied and optional accessories are not waterproof.
Waterproof property
Do not use the product in places where it may be sprayed with high-pressure
water (e.g. near a faucet or showerhead) or submerge it in water for extended
periods of time, as the product is not designed to withstand high water pressure.
Also, do not expose the product to a water flow stronger than the specified flow
rate (i.e. 6 liters per minute from a faucet or showerhead, at which you might
even feel pain in the skin). Doing so might cause a fault, even though the product
has a waterproof property equivalent to IPX5. Do not wash the product in a
washing machine or ultrasound bath.
This product does not float on water.
Heat resistance
Do not use the product in places where boiling water may splash on it, in saunas
or near hot air (e.g. hairdryer). The product is not resistant to high temperatures.
Shock
Intentionally subjecting the product to extreme force such as throwing it or letting
it drop might break the product. While performance of the product may not be
affected, dropping or subjecting it to shock produces scratches, etc.
Do not jab the earpiece, microphone, speaker, etc. with a cotton swab or any
sharp object. Doing so might damage or deform the product causing water
intrusion.
