Rexton Reach R-Li and R-Li T have an ATEX certification which verifies that they are tested and approved to be intrinsically safe for use in potentially explosive environments.
They can be safely used in areas where there may be flammable substances in the air such as paint and chemical manufacturing, petrol stations and mills.
The ATEX group/class is printed on the ATEX card, which must be available at hand when the hearing aids are used in explosive atmospheres. Ask your hearing care professional for your ATEX card.
