Waterproof and dust proof performance of the unit
The unit, with the cap fastened securely, has a waterproof specification of IPX7*1 as specified in “Degree of protection against water immersion” of the IEC60529 “Ingress Protection Rating (IP Code)”*3, and a dust proof specification of IP6X*2 as specified in “Degrees of protection against solid foreign objects”*3.
Liquids that the waterproof performance specifications apply to
|Applicable||fresh water, tap water, pool water, salt water|
|Not applicable||liquids other than the above (soapy water, water with detergent or bath agents, shampoo, hot spring water, etc.)|
*1 IPX7 equivalency: The speaker has been tested to and maintains its operability when gently submersed in water to a depth of 1 m (3.2 ft) and left for 30 minutes.
*2 IP6X equivalency: The speaker has been tested to and continues to block dust after stirring for 8 hours in a testing device which contains dust particles that are up to 75 μm in diameter.

The waterproof and dust proof performance of the unit is based on our measurements under the conditions herein described. Note that malfunctions as a result of water immersion or dust intrusion caused by misuse by the customer are not covered by the warranty.
To avoid deterioration of waterproof and dust proof performance
Check the following and use the unit correctly.
The unit passes the drop test from 1.22 m (4 ft) on plywood of 5 cm (2 in) thickness conforming to MIL-STD810G Method 516.7-Shock. However, this does not guarantee no damage, no breakdown, or waterproof and dust proof performance in all conditions. Deformation or damage from dropping the unit or subjecting it to mechanical shock may cause deterioration of the waterproof and dust proof performance.
Do not use the unit in a location where large amounts of water or hot water may splash on it. The 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 under running water or 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 waterproof and dust proof 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 waterproof and dust proof performance may deteriorate and may cause a malfunction of the unit as a result of water or dust particles entering the unit.
