What is an IP rating? Does an IP68 rating mean a device is waterproof?

Ingress Protection (IP) rating is set by the International Electrotechnical Commission. The IP rating is a combination of protection against dust and other solid particles and protection against the effects of continuous immersion in water.⁶

Devices that meet the IP68 rating are considered waterproof.

Are the Nucleus 8 Sound Processor and Kanso 2 Sound Processors IP68 waterproof* without using the Nucleus Aqua+ kit or Aqua+?

Yes, the Nucleus 8 Sound Processor and Kanso 2 Sound Processors are IP68 waterproof* without the Aqua+ and can be continuously submerged in freshwater for 60 minutes at a depth of 1 meter.

Can I go swimming with the Nucleus 8 or Kanso 2 Sound Processor?

Yes, you can swim the Nucleus 8 Sound Processor with the rechargeable battery and the Kanso 2 Sound Processors continuously submerged in freshwater for 60 minutes at a depth of 1 meter.

In which activities should I use the Aqua+ kit?

You should use the Aqua+ kit for extended water use, use in rushing water, extra peace of mind in dirty water or in saltwater environments. Whether or not you choose to use the Aqua+ accessory it is ALWAYS recommended to use retention aids to ensure processors are retained during activity.**

If the Nucleus 8 and Kanso 2 Sound processors are IP68 waterproof*, why should I use the Aqua+ kit during saltwater activities?

You should use the Aqua+ kit during saltwater activities as the IP68 rating is a test performed in freshwater.

Do I still need to use the Dry and Store?

Yes, as part of routine device maintenance Cochlear recommends using the drying kit.
