Daily Maintenance
Keep your hearing instrument clean and dry. Wipe the case with
a soft cloth or tissue after use to remove grease or moisture. You
should avoid exposing your instrument directly to moisture
such as rain or water from the shower. If your instrument does
get wet or if it has been exposed to high humidity or perspira-
tion, it should be left to dry out overnight with the battery out
and the battery compartment open. It is also a good idea to put
them in a sealed container together with a drying agent (des-
sicator) overnight. Consult your hearing care professional as to
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 sun-
light since excessive heat can damage the instrument or de-
form the casing or the receiver tube.
The Receiver Tube
The Receiver Tube comes in two different types;
MPG (Medium Power Gain)
and HPG (High Power Gain).
Please see illustrations.
Depending on your hearing
loss you have either been fitted
with the MPG or the HPG receiver
type. Please see page 27 to see your selected type. The re-
ceiver tube contains the wiring to the receiver which de-
livers the sound direct in the ear canal. It is important that
the receiver tube and the receiver dome/RIE Mold fit cor-
rectly into your ear. If the receiver tube or the receiver dome/
RIE Mold irritate your ear in any way and prevent you
from wearing your hearing instrument, please contact your
hearing care professional. You should never attempt to modify
the shape of the receiver tube yourself. The receiver tube and
the receiver dome/RIE Mold should be cleaned regularly.
Please see instructions on the next page.
Cleaning the Receiver Tube and the Receiver Domes
The receiver tube and the receiver dome should be cleaned re-
gularly. Use a damp cloth to clean the receiver tube and receiver
dome on the outside. Do not use water when you are cleaning
the receiver tubes or the receiver domes. Please see instruction on
page 18 for how to change the HF3 wax guard filter.
