gets into the interior of the product, it might cause
overheating or a fault.

• 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 temporarily making it harder to hear the
sound.

not directly apply high water pressure to or immerse
the product for a prolonged period.
