Warning to hearing healthcare professional: Domes should never

be tted on patients 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 patient’s head
so you are looking
straight into the patient’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 patient’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 the
hearing instrument.

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 patient’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
patient’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.

10

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.

2. Go to the Acoustics screen in the Instruments
menu.

3. Select the connected Receiver unit for each hearing
instrument from the drop-down lists.

4. Select the connected tip from the drop down list. If
applicable, choose the appropriate size of venting.

5. If custom shell is selected and has the IntelliVent
technology, enter the IntelliVent code for optimal
venting acoustics. The IntelliVent coupling code is
inscribed on the custom shell.

Whenever a change to the xReceiver unit or dome
is made during the tting, you need to revisit the
Acoustics screen and specify your choices to allow for
correct gain calculations.

Note: Please ensure that the connected xReceiver unit is

selected and a QuickFit is performed before inserting hearing
instrument into your patient’s ear canal.

Once your setup selection is complete, go to Feedback
Optimization under Fitting.

Using the Moxi2 shell removal tool

The shell removal tool is used to remove the top shell
from Moxi

2

to access the microphone protector.

Note: Moxi

2

Kiss and Moxi Dura models do not have a
replaceable microphone protector. It is not necessary to
remove the shell.

Removing the top shell of Moxi

2

1. Open the battery door and insert the tool on a slight
angle, inserting one pin on the side of the tool with
the notch inside the battery compartment.

2. Twist the tool down in the opposite direction to
snap the tool into place.

3. Squeeze the tool in the center to push the shell out
of the notches.

4. Li the shell up and forward o the hearing
instrument and over the push button. This allows
access to the microphone protector.

15

Replacing the top shell

1. Position the top shell over the push button on the
hearing instrument.

2. Then push the shell down and back until it snaps
into place.

Microphone protector replacement

The microphone protector prevents moisture and
debris damage to the microphone. A clogged
microphone protector could aect the performance of
the hearing device. If this occurs, the mic protector can
be easily replaced.

Removal

1. Aer removing the top shell (shown on previous
page), remove the microphone protector with a
tweezer.

Installation

1. Place the new mic protector with a tweezer.

2. Smooth down the mic protector with your nger.

3. Replace the top shell.

How to measure performance in a coupler

RIC devices should be measured with a HA1 coupler
since it best reflects the acoustical properties in the ear
canal.

The xReceiver kit includes a metal adapter plate that
ts on a HA1 coupler and allows for a good connection
of the xReceiver unit to the coupler.

Select Activate Test Box Measurement Mode in
Unitron TrueFit soware from the menu on the top
menu bar. Clicking on Activate Test Box Measurement

Mode disables the adaptive features and activates

the omnidirectional microphone mode to allow for
correct measurements. Click on Deactivate Test Box

Measurement Mode to reestablish the previous

settings.

Attach the standard xReceiver to the metal adapter plate.

Wax guard replacement and cleaning domes

All xReceiver units are equipped with a wax guard
system to protect the xReceiver from ear wax. The wax
guard can be easily replaced. You will need to counsel
your patient on how to replace the wax protector, see
instructions included with the replacement packs.

If necessary, the domes and xReceiver units can be
wiped with a damp cloth; however, xReceiver units
should never be submerged in water to avoid damage
to the electrical components.
