The Receiver Tube
The Receiver Tube comes in two different types; NP (Nor-
mal Power) and HP (High Power).
Please see illustrations.
Depending on your hearing loss
you have either been fitted with
the NP or the HP receiver type.
Please see page 29 to see your
selected type. The receiver tube contains the wiring to the
receiver which delivers the sound direct in the ear canal. It
is important that the receiver tube and the receiver dome/
RIE Mold fit correctly into your ear. If the receiver tube or
the receiver dome/RIE Mold irritate your ear in any way and
pre vent you from wearing your hear ing instrument, please
contact your hearing care pro fessional. 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 in the next section.
Cleaning the Receiver Tube and the Receiver Domes
The receiver tube and the receiver dome should be clea-
ned regularly. 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 19 or 20 for how to
change the HF3 wax guard filter.
Daily Maintenance
Keep your hearing instrument clean and dry. Wipe the
case with a soft cloth or tissue after use to remove gre-
ase or moisture. You should avoid exposing your instru-
ment 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 perspiration, 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
(dessicator) overnight. Consult your hearing care profes-
sional as to which drying agent to use.
To avoid the need for unwarranted repairs:
• Never immerse the instrument in water or other li-
quids since this may cause permanent damage to the
circuitry.
• Protect your hearing instrument from rough hand-
ling, and avoid dropping it on hard surfaces or flo-
ors.
• Do not leave the instrument in or near direct heat or
sunlight since excessive heat can damage the instru-
ment or deform the casing or the receiver tube.
