Notes…on…Usage
Important…precautions
• To ensure waterproof property of the product,
make sure that the au IC card tray is securely
attached.
• Never open or close the au IC card tray
when your hand and/or the product is wet.
• Do not immerse the product in or splash
the product with liquid other than tap
water (seawater, pool, hot spring, soap
water, detergent water, water with bath
salts in it, alcohol, beverages, seasonings,
etc.). Also, do not use the product in
places subject to splashing with pet urine.
In the event that the product is splashed
with such liquids, rinse off immediately
with tap water.
• Do not place the product directly on beach
sand, etc. Sand or other small particles
might get inside the receiver/speaker, the
mouthpiece/microphones (upper/lower),
the vent hole, the microphone (rear) or the
speaker, causing the volume to drop. If sand
gets into the interior of the product, it might
cause overheating or a fault.
• Do not use the product underwater.
• Do not use or store the product in a
bathroom, kitchen or other highly humid
areas for a prolonged period.
• There may be some water remaining
on the product even after draining it.
The product can be used normally, but
remember to keep it away from objects
you do not wish to get wet. Also be careful
as your clothes, bag, etc. may get wet
from the water remaining on the product.
• You need to perform draining if water
accumulates in the mouthpiece/
microphones (upper/lower) or receiver/
speaker temporarily making it harder to
hear the sound.
