Daily Maintenance

Keep your hearing instrument clean
and dry. Wipe the case with a soft
cloth/brush or tissue after use to
remove oil or moisture. If the instru-
ment has been exposed to high hu-
midity or perspiration, enclose it in a sealed container together
with a drying agent (desiccant) overnight. Consult with your
hearing care professional regarding which drying agent to use.
To avoid the need for unwarranted repairs:
• Never immerse the instrument in
water or other liquids since this
may cause permanent damage
to the circuitry.
• Protect your hearing instrument
from rough handling, and avoid
dropping it on hard surfaces or
floors.
• Do not leave the instrument in or near direct heat or sunlight
since excessive heat can damage the instrument or deform
the casing.

Cleaning the Microphone Sound Inlet

For proper function of the microphone, it is important to clean
the sound inlet to remove dust, ear wax or other debris. The soft
brush, provided with your hearing instrument, can be used for
this purpose. Consult your hearing care professional regarding
proper use of the tool.

Changing the Sound Outlet Filter/Cleaning the Sound Outlet
Your ReSound Match hearing instrument may be equipped with
a sound outlet filter (consult your hearing care professional).
This filter is located at the end of the sound outlet and prevents
debris from getting into the hearing instrument. If the hearing
instrument seems to have lost power and changing the battery
does not help, the filter may be blocked, and need to be chan-
ged. Your hearing care professional can instruct you on how to
change the filter. If your hearing instrument does not have a fil-
ter, ear wax and/or other debris may collect in the sound chan-
nel. The cleaning loop, provided with your hearing instrument,
can easily be used to remove this material. Your hearing care
professional can instruct you on how to properly use this tool.
When using this tool, be careful not to damage or pull the tu-
bing placed at the opening of the sound outlet. If this is pulled
out, the hearing instrument may need to be returned for repair.

Repairs

If your GN ReSound hearing instrument malfunctions, it must
be repaired by a qualified technician. Do not attempt to open
the case of the hearing instrument since this would invalidate
the warranty. If your GN ReSound hearing instrument requires
service, please contact your hearing care professional for assi-
stance.
