Dysfunction in hearing devices
• Hearing devices may stop functioning, for instance
if the batteries have expired or if the receiver/loud-
speaker 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 devices have 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 electromagnetic
radiation, leading to unforeseen interference in
hearing devices. Examples include induction
cooking appliances, shop alarm systems, mobile
telephones, fax machines, personal computer
devices, X-rays, Computer tomography, etc.
Possible side effects
• Hearing devices may cause an accelerated
accumulation of cerumen (earwax).
• The otherwise non-allergenic materials used in
hearing devices may in rare cases cause a skin
irritation.
Consult a doctor if you experience any of these side
effects.
