Safety Precautions
Important Items to Remember
before Use
● Make sure the back cover is completely
attached. Water resistance is effective when
completely sealed.
● Never open/close the back cover when the
product or your hands are wet.
● Do not let the product submerged into or get
wet with the liquids (seawater, water from a
swimming pool, hot water of hot spring, water
containing soap, detergent, bath powder,
alcohol, soft drink, seasoning, etc.) other than
tap water. Do not use it in a place where it
gets wet with pet urine either.
If the product gets splashed, immediately
rinse it off with tap water.
● Do not place the product directly on sand at
a beach, etc. Sand or other small particles
might get inside the earpiece/speaker or
mouthpiece (microphone), causing the volume
to drop. If sand gets inside the product from
hinges, it might cause overheating or a fault.
● Do not use the product underwater.
● Do not use or leave the product in a humid
place such as a bathroom or kitchen for an
extended period of time.
● Moisture may still remain after draining. While
this will not affect use, you should not leave
the product next to items you do not want to
get wet. The product may wet clothing, inside
of carry bag, etc.
● Drain any water in the earpiece/speaker or
mouthpiece (microphone) that may be
affecting audibility.
● The product is not designed to resist water
pressure. Avoid exposing to high water
pressure or submersing in water for a long
period.
● Do not wash the product in a washing
machine or ultrasonic bath.
● Do not immerse the product into a bathtub.
The product is not designed to be heat
resistant.
● The rapid changes of temperature may cause
condensation, resulting in malfunction. Wait
until the product reaches room temperature
before you bring the product from a cold
place into a warm bathroom.
● The product does not float on water.
■Back cover
●Make sure the back cover is completely
attached. Any minute particles becoming
lodged between contact surfaces (a single
hair, etc.), no matter how small, can cause
seepage.
