Notes on water resistant feature

Water resistant performance of the unit

This unit has a water resistant specification*1 *2 of IPX5*3 as specified in “Degrees of protection against ingress of water” of the IEC60529 “Ingress Protection Rating (IP Code).” However, this unit is not completely water-tight. Do not drop the unit into hot water in a bathtub or purposely use it in water.

Liquids that the water resistant performance specifications apply to

Applicable fresh water, tap water
Not applicable liquids other than the above (soapy water, water with detergent or bath agents, shampoo, hot spring water, pool water, seawater, etc.)

*1 Requires that the cap is fastened securely.

*2 The supplied accessories and the connectors of this unit (USB/AUDIO IN) are neither water resistant nor dust proof.

*3 IPX5 (Degree of protection against jets of water): The speaker has been tested and found to remain functional after exposure to direct jet streams of water using a nozzle of 6.3 mm (about 1/4 in) internal diameter from any direction where approximately 12.5 L/min of water is applied for a period of more than 3 minutes from a distance of about 3 meters (about 10 ft).

The water resistant performance of the unit is based on our measurements under the conditions herein described. Note that malfunctions as a result of water immersion caused by misuse by the customer are not covered by the warranty.

To avoid the deterioration of the water resistant performance

Check the following and use the unit correctly.

  • Be careful not to drop the unit or subject it to mechanical shock.

    Deformation or damage may cause deterioration of the water resistant performance.

  • This unit does not have a design that is resistant to water pressure. Use of the unit in a location where high water pressure is applied, such as in the shower, may cause a malfunction.

  • Do not pour high-temperature water or blow hot air from a hair dryer or any other appliance on the unit directly. Also, never use the unit in high temperature locations such as in saunas or near a stove.

  • Handle the cap with care. The cap plays a very important role in maintenance of the water resistant performance. When using the unit, make sure that the cap is closed completely. When closing the cap, be careful not to allow foreign objects inside. If the cap is not closed completely, the water resistant performance may deteriorate and may cause a malfunction of the unit as a result of water entering the unit.
