General warnings
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, and
never dispose of batteries by burning them.
There is a risk that the batteries will explode.
Dysfunction
·
Be aware of the possibility that your hearing aid
may stop working without notice. Keep this in mind
when you depend on warning sounds (e.g. when
you are in traffic). The hearing aids may stop
functioning, for instance if the batteries have
expired or if the tubing is blocked by moisture or
ear wax.
