The waterproof and dust proof 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 avoid the deterioration of the waterproof and dust proof performance

Check the following and use the speaker correctly.

  • This speaker does not have a design that is resistant to water pressure. Use of the speaker 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 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 capwith care. The cap plays a very important role in maintenance of the waterproof and dust proof 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 dust proof performance may deteriorate and may cause a malfunction of the speaker as a result of water or dust particles entering the speaker.
