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 (for example
when you are in trafc). The hearing aids may stop
functioning, for instance if the batteries have
expired or if the tubing is blocked by moisture or
ear wax.
Active implants
· Caution must be taken with active implants.
In general, follow the guidelines recommended by
manufacturers of implantable debrillators and
pacemakers regarding use with mobile phones and
magnets.
· The Auto Telephone magnet and MultiTool (which
has a built-in magnet) should be kept more than
30 cm away from the implant, for example, do not
carry it in a breast pocket.
· If you have an active brain implant, please contact
the manufacturer of your implantable device for
information about the risk of disturbance.
X-ray, CT, MR, PET scanning and electrotherapy
· Remove your hearing aid before X-ray, CT/MR/PET
scanning electrotherapy, surgery etc. as your
hearing aid may be damaged when exposed to
strong elds.
