Notes on waterproof and dustproof features
On waterproof and dustproof performance of the speaker
The speaker, 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 dustproof 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.
*3 The supplied accessories and the connector of this speaker (USB) are neither waterproof nor dustproof. To reduce the risk of fires or electric shocks, do not expose the speaker to water or droplets while using the connector (USB).
The waterproof and dustproof performance of the speaker 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 maintain waterproof and dustproof performance
Carefully note the precautions below to ensure proper use of the speaker.
-
The speaker passes the drop test from 1.22 m (4.0 ft) on plywood of 5 cm (1.97 in) thickness conforming to MIL-STD810H Method 516.8-Shock. However, this does not guarantee no damage, no breakdown, or waterproof and dustproof performance in all conditions. Deformation or damage from dropping the speaker or subjecting it to mechanical shock may cause deterioration of the waterproof and dustproof performance.
-
Do not pour high-temperature water or blow hot air from a hair dryer or any other appliance on the speaker directly. Also never use the speaker in a place subject to high temperatures, such as in a sauna or near a heat source.
-
Handle the cap (
) with care. The cap plays a very important role in maintenance of the waterproof and dustproof performance. When using the speaker, 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 dustproof performance may deteriorate and may cause a malfunction of the speaker as a result of water or dust particles entering the speaker.
