Warning to hearing healthcare professional: Domes should
never be tted on clients with perforated eardrums, exposed
middle ear cavities, or surgically altered ear canals. In the
case of such a condition, we recommend to use a customized
ear mold. In the unlikely case that any parts remain in the ear
canal aer the removal of the hearing instrument, contact a
physician immediately.

To measure for an accurate wire length:
1. Place your head
at the same
horizontal level as
the client’s head
so you are looking
straight into the client’s ear that you wish to t with
the hearing instrument.
2. Hold the measurement tool with the
appropriate blue or red color code
marking (for the le or right ear) with
your thumb placed on the ear diagram.
3. Place the measurement tool on
the top of the ear and in contact
with the skin in the narrow gap
between the head and the pinna.
Keep the horizontal line on the
measurement tool horizontal and level.
Measuring for an accurate xReceiver unit
Choosing the correct xReceiver wire length will ensure
a more accurate, comfortable t. The measurement
tool included in the kit allows for a quick and simple
measurement and has the following features:
Color Code Markings – blue
(le ear) and red (right ear)
color code markings to indicate
which of the client’s ears to
measure.
Horizontal Line Markings – measurements must be
made horizontally with the measurement tool touching
the skin in the gap between the head and the top of the
pinna.
Four Horizontal Sightlines – (0-1-2-3) – to indicate which
wire length you should use for an accurate tting.

Modifying xReceiver wire to improve t
In some cases, you might nd that the
wire of the xReceiver unit does not lie
close to the side of the head or follow
the shape of the ear.
First, ensure the selected dome and
xReceiver unit sizes are appropriate
(see following pages).
If a dierent xReceiver tube does not
t better, you may need to modify the
curvature (bend) slightly using the
steps outlined below.
1. Remove the xReceiver unit from
Moxi.
2. Heat the tube carefully with a hairdryer at a low
setting for a few seconds.
3. Do not use excessive heat to avoid damage to the
electrical components.
4. Bend the tubing into the desired shape and hold
until it has cooled o. Once completely cooled, the
tube will maintain its new shape.
4. Choose the sightline (0-1-2-3) on
the measurement tool that is most
parallel with the top of the opening
of the ear canal. In this example,
the sightline marked 1 would be the most accurate
choice.
5. Make a note of the sightline chosen and then
repeat steps 1-4 on the opposite ear for a binaural
tting.
Note: It is important to measure the opposite ear for a binaural
tting since right and le ear sizes can vary and thus, require
dierent wire lengths.

Attaching the retention piece tothe
standard or power xReceiver unit
The retention piece may be used for ttings with
the open or closed dome depending on the client’s
requirements. The retention piece is optional and
allows for extra security in the ear. The retention piece
can easily be cut shorter to comfortably t into the
client’s concha bowl.
To attach the retention piece
1. Slide the retention piece over the receiver.
2. The retention piece should be secured over the
receiver so it appears as one piece.

Attaching the dome or sleeve mold
to the standard xReceiver unit
1. Hold the xReceiver unit in one hand and the
coupling (i.e. dome or sleeve mold) in the other
hand.
2. Slide the appropriate coupling over the receiver.
3. The xReceiver unit and coupling should t snugly
together.
Attaching the power dome to the
power xReceiver unit
1. Hold the xReceiver unit in one hand and the power
dome in the other hand.
2. Slide the power dome over the receiver.
3. The xReceiver unit and power dome should t
snugly together.
