CARE
Your processor is protected against failure from dust and
temporary immersion in water (IP57 rated) when you
wear it with:
• a rechargeable battery
module
• a coil
• no acoustic component.
If you use a disposable battery module instead of a
rechargeable battery module or use the processor with
an acoustic component worn in the ear, it is protected
against failure from dust and splashing water
(IP54 rated).
