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 fi t if you
choose a slightly longer wire length than you
would when fi 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 fi 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 fi 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.

Speaker units can easily sustain internal
damage if dropped. Before you attach the
speaker unit, please place a dome on the
speaker to protect it.
