Heat and chemicals
· The hearing aid must never be exposed to extreme heat,
for example, left inside a parked car in the sun.
· The hearing aid must not be dried in microwave ovens
or other ovens.
· The chemicals in cosmetics, hairspray, perfume,
aftershave lotion, suntan lotion and insect repellent can
damage the hearing aid. Always remove your hearing
aid before applying such products and allow time to dry
before use.
Power instrument
· Special care should be exercised in selecting, fitting and
using a hearing aid where maximum sound pressure
capability exceeds 132 dB SPL (IEC 711), as there may be
risk of impairing the remaining hearing of the hearing
aid user.
For information on whether your hearing aid is a power
instrument, see the "Model overview" section in the front
of this booklet.
Possible side effects
· Hearing aids and earpieces may cause an accelerated
accumulation of ear wax.
· The otherwise non-allergenic materials used in hearing
aids may in rare cases cause a skin
irritation or other side effects.
Please seek consultation with a physician if these
conditions occur.
