6. Care
6.1 Care and maintenance
Your sound processor is a delicate
electronic device. Follow these guidelines
to keep it in proper working order:
• For cleaning your sound processor
and snap coupling, remove the sound
processor from your head and use
the Baha sound processor cleaning
kit and accompanying instructions.
The kit is provided by Cochlear in the
sound processor box.
• After exercise, wipe your processor
with a soft cloth to remove sweat or
dirt.
• If the sound processor gets wet
or is exposed to a very humid
environment, dry it with a soft cloth,
remove the battery and let the
processor dry out before inserting a
new one.
• Remove your sound processor before
applying any hair conditioners,
mosquito repellent or similar
products.
• Turn off and store the sound
processor away from dust and dirt.
• A storage case is provided by
Cochlear in the sound processor box.
• Avoid exposing your sound processor
to extreme temperatures.
• For long-term storage, remove the
battery.
CAUTION
Do not use other cleaning methods
than recommended by Cochlear.
6.2 IP classification
The electronics compartment in your
sound processor is protected against
damage by dust and by immersion in
water. Without the battery, the sound
processor was tested for immersion in
water for 35 minutes at 1.1 meters depth
and achieved an IP68 rating. This means
that if you, for example, accidentally
drop your sound processor in water, the
electronics in the device are protected
against malfunction due to water ingress.
However, your sound processor has a
battery that requires air to operate and
malfunctions if wet. The sound processor
with battery achieves an IP42 rating. This
means there is a possibility that if you,
for example, are out in rain or in other
humid environments, water can block air
supply to the battery causing a temporary
malfunction. To avoid temporary
malfunction, avoid exposing the sound
processor to water and always remove it
before swimming or bathing.
