Battery use
•
Always use batteries recommended by your hearing care
professional. Batteries of low quality may leak and cause
bodily harm.
•
Never attempt to recharge your batteries. They may explode
and cause serious injury.
•
Never dispose of batteries by burning them. There is a risk
that they will explode and cause serious injury.
Disfunction in hearing instruments
•
Hearing instruments may stop functioning, for instance if
the batteries have expired or if the tubing is blocked by
moisture or earwax. You should be aware of this possibility,
in particular when you are in traffi c or otherwise dependent
on warning sounds.
Interference
•
Your hearing instrument has been thoroughly tested for
interference, according to the most stringent international
standards. But new technical developments constantly
bring new products into society, and some may emit elec-
tromagnetic radiation, leading to unforeseen interference
in hearing instruments. Examples include induction cooking
appliances, shop alarm systems, mobile telephones, fax
machines, personal computer devices, X-rays, Computer
tomography etc.
