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.

Choosing the correct coupling for standard xReceivers

Determine the correct dome size based on your otoscopic examination of the ear canal.
Selectthedometypebasedon the audiometric requirements and tting ranges shown on this page.
Allowthedome to t comfortably in the ear canal.
