Now, you can keep it cleaner than ever by washing it thoroughly with foaming hand soap or body soap,

In the kitchen! / By the sink! / In the bathroom!
  1. IPX5/8 waterproof performance. Kyocera conducted a proprietary durability test (wash cycle tests performed by hand washing and rinsing, using foaming hand soap and foaming body soap).

    foaming body soap produced by Japanese manufacturers. Do not wash with kitchen-use, industrial-use, or additive-free hand soap, or industrial-use, additive-free, or alkaline body soap.

  • When rinsing, use tap water (warm water with an approximate temperature of 30°C) running weakly, and ensure that the soap is rinsed off thoroughly.

    After washing, gently press a dry soft cloth against the handset to thoroughly remove any excess water.

  • Do not mix different types of hand soap or body soap. Alkaline detergents do not cause any issues with handset functions, but may cause color changes under high temperatures, such as when in a bathroom or when the detergent is warm. It was confirmed that the device maintains its functionality in the testing environment, but proper functionality cannot be guaranteed when washing with all types of foaming hand soap or foaming body soap. In addition, the tests do not guarantee that the handset will remain free from malfunction. For washing instructions and precautions, check the au website (product page) or the instruction manual.
