1 Place the measurement tool over the ear,
keeping the top line horizontal. With your eyes
at the same level as the ear, determine which
mark is closest to an imaginary line running
over the top of the ear canal. In this example,
the correct choice is size 2.
Power Molds will have a better t if you
choose a slightly longer wire length than you
would when tting a Power Dome. If the top
of the ear canal falls between two numbers on
the gauge, choose the higher number.
2 If the speaker unit wire is too long the hearing
instrument will fall back over the ear and the
microphones will point vertically instead of
horizontally. It is also unlikely that the receiver
wire will t the contours of the ear correctly.
3 If the speaker unit wire is too short, it will
have a tendency to move out of the ear canal,
and the hearing instrument will lose stability
on the ear.

Four receiver lengths are available for both the M-Speaker and the P-Speaker. No. 1 is the shortest
while no. 4 is the longest. Before tting Nano RITE hearing instruments, it is necessary to determine
the correct speaker unit length. The measurement procedure is the same for both the M-Speaker and
the P-Speaker.

Attaching the Speaker Unit to a Nano RITE Hearing System
Correct speaker unit attachment is imperative.
1 Slide the connector plug into the connector
socket of the instrument. Take care to align the
pins in the connector plug with the socket.
2 When the connector plug is correctly aligned,
push it gently into place.
3 Take the lock pin out of the packaging in which
the speaker unit is delivered (tweezers make
this easier). Insert the lock pin with the
tweezers.
4 Ensure that the lock pin is fully inserted into
the hearing instrument. Use the back side of
the tweezers tool if necessary.
5 To test the attachment of the speaker unit to
the hearing instrument, gently pull the speaker
wire near the connection to the hearing
instrument as shown. If the speaker comes
off, then it was not attached properly.

Detaching the Speaker Unit from a Nano RITE Hearing System
1 Use the pointed end of the disassembly tool to
push the lock pin free.
2 Hold the instrument rmly with one hand
and with the other hand hold the edge of the
connector plug between your thumb and
forenger.
3 Gently pull the connector plug out of the
socket. If it does not come out easily, verify
that the lock pin is completely free.
4 Avoid losing the lock pin due to the fact that
you will need it for reattaching the speaker to
the hearing instrument.
Do not attempt to detach the speaker unit
by pulling on the wire without pushing
the lock pin free. This could damage both
the speaker unit and the hearing
instrument.

M-Speaker Unit
The M-Speaker unit is suitable for mild to moderately severe losses and comes in four lengths. It can
be used for both instant and custom ttings.
1 To obtain a more secure hold in the ear canal,
an ear grip should be used. The same version
works for both the left and the right ear. Insert
the ear grip in the slot in the receiver as
shown, noting the orientation.
If the ear grip seems too long, it may be
trimmed to the desired length. Be careful not
to leave a sharp end when cutting since this
could cause irritation in the ear.
2 To remove the ear grip, push it in the opposite
direction.

CN_ILLU_NREarGripMspeakerAttaching2_CMYK_HI
CN_ILLU_NREarGripMspeakerAttaching3_CMYK_HI
CN_ILLU_NREarGripMspeakerAttaching4_BW_HI
During insertion, the top of the ear grip
should point towards the speaker wire as
illustrated. Pull the ear grip down until
the top disappears into the slot.
If inserted in the wrong direction, the
ear grip will not be oriented properly to
place in the concha.

Custom Molds for the M-Speaker
For custom ttings two different types of molds can be attached to the M-Speaker. The Micro Mold
and the Lite Tip come with an adapter already inserted, colored red (right) or blue (left) to indicate
which ear. The color dot on the top of the custom mold indicates the front and top position in the ear
canal.
Tools for Custom Molds
To attach and detach the M-Speaker unit to and from a custom mold, two different tools are designed
to be used.
Lite Tip Tool for Lite Tip and Micro Mold

P-Speaker Unit for Power Fittings
The P-Speaker unit contains a high performance receiver which requires ample room in the ear canal.
To determine if your client’s ear canal can accommodate this receiver, please use the measurement
gauge supplied. This step is necessary for both instant ttings with the Power Dome and custom
ttings with molds.
Using the Measurement Gauge
1 Hold the handle of the measurement
gauge so that the at side of the handle
is up.
2 Insert the gauge into the ear canal (with
the at side up) until the size indicator is
fully surrounded by the ear canal. If the
size indicator ts easily within the ear
canal, the client is an excellent candidate
for the P-Speaker unit.
3 If the size indicator does not t in the ear
canal but is hidden behind the tragus when
viewing from a 45° angle, the P-Speaker
with Canal Mold can still be produced.
4 If the size indicator is visible when viewed
from a 45° angle, the client is NOT a candidate
for the P-Speaker unit.
Size indicator Flat side
Handle
The gauge must be cleaned and sterilized
properly before re-use. First clean any
visible cerumen from the gauge with a
clean dry or moist tissue. Next soak the
gauge in a cold sterilant for at least
6 hours.
