On the water resistance of the unit

• The charging case is not water resistant.
• Unless the unit is used correctly, water may get into the unit and cause fire, electrocution, or malfunctions.

Note the following cautions carefully and use the unit correctly.

To maintain water-resistant performance

Carefully note the precautions below to ensure proper use of the unit.

• Do not splash water forcibly into the sound output holes.
• Do not drop the unit into water, and do not use underwater.
• Do not allow the unit to remain wet in a cold environment, as the water may freeze. To prevent malfunction, make sure to wipe off any water after use.
• Do not place the unit in water or use it in a humid place such as a bathroom.
• Do not drop the unit or expose it to mechanical shock. Doing so may deform or damage the unit, resulting in deterioration of water resistance performance.

On BLUETOOTH® communications

• Microwaves emitting from a Bluetooth device may affect the operation of electronic medical devices. Turn off this unit and other Bluetooth devices in the following locations, as it may cause an accident:
  • In hospitals, near priority seating in trains, locations where inflammable gas is present, near automatic doors, or near fire alarms.

On charging the unit
