Slim tube HE fitting
Thank you for choosing the slim tube HE option, designed
to provide comfortable, non-occluding fittings with added
high frequency emphasis.
Whether you are an experienced fitter of slim tube
systems or new to this type of fitting, this guide will
explain step-by-step how to assemble the parts of the
system and fit the hearing instrument on your client. The
guide will introduce you to the parts of the system, how
to measure for the right tube length, choose the correct
dome size, and how to attach the slim tube HE to the
hearing instrument so you are ready to program in
TrueFit™.
Warning to hearing healthcare professional: Domes should
never be fitted 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 after the
removal of the hearing instrument, contact a physician immediately.

Slim tube HE sizes
Slim tube HE is available in four different lengths to
meet the needs of your clients. The red or blue numeric
code on the slim tube identifies the ear to which it
belongs (blue = left ear; red = right ear) as well as the
tube length. Refer to the following chart to identify the
various slim tubes that are available:

Choosing the correct slim tube HE length will ensure a
more accurate, comfortable fit. The measurement tool
included in the kit allows for a quick and simple
measurement and has the following features:
Color Code Markings – blue (left
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
tube length you should use for an accurate fitting.
To measure for an accurate slim tube HE 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 fit with the hearing instrument.
2. Hold the measurement tool with the
appropriate blue or red color code
marking (for the left 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.
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 fitting.
Note: It is important to measure the opposite ear for a
binaural fitting since right and left ear sizes can vary
and thus, require different slim tube HE lengths.

Measuring for an accurate slim tube HE length

Choosing the correct domes
Do an otoscopic examination of the client’s ear canal.
Based on the examination, choose an appropriate dome
to fit the ear canal.
Attaching and removing domes
To attach the dome, push the dome onto the slim tube HE
until it touches the plastic ring.
To remove the dome, grasp the dome between the thumb
and forefinger and pull it off the slim tube HE.

To attach the slim tube HE:
1. Unscrew the earhook from the hearing instrument.
2. Hold the slim tube with the dome attached in one hand
and the hearing instrument in the other hand.
3. Gently turn the hearing instrument onto the slim tube
until it is snug.
Note: To prevent damage to the slim tube, it is recommended
that you turn the hearing instrument onto the slim tube and
not vice-versa.
To remove the slim tube HE:
1. Unscrew the slim tube HE from the hearing instrument
gently.
In some cases, you might find that the slim tube HE does
not lie close to the side of the head or follow the shape of
the ear.
First, ensure the selected dome and slim tube HE sizes
are appropriate (see previous pages).
If a different slim tube HE does not fit better, you may
need to modify the curvature (bend) slightly using the
steps outlined below.
1. Remove the slim tube HE 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
tube.
4. Bend the tubing into the desired shape and hold until
it has cooled off. Once completely cooled, the tube will
maintain its new shape.

Modif ing the slim tube HE to
improve fit

Once you have attached the slim tube HE with dome to
the hearing instrument, you are ready to place the
hearing instrument on the client’s ear.
1. Place the hearing instrument over the top of the ear.
2. Hold the slim tube HE where it attaches to the dome
and gently push the dome into the client’s ear canal.
The dome should be placed far enough into the ear so
that the slim tube HE lies flush against the head.
When looking at your client face-to-face, you should
not see the slim tube HE sticking out.
3. Place the retention piece of the slim tube HE into the
concha bowl.
Note: If the retention piece is too long, you may cut the length
slightly. Be careful not to shorten the length too much, as it
could affect retention in the ear.

The slim tube HE and dome need to be changed every
three months or when they become stiff or brittle. As part
of the fitting, you will need to counsel the client on how
to clean the dome and the inside of the slim tube HE.
Clients should wipe the dome daily with a damp cloth.
They should also clean the slim tube HE periodically, with
the cleaning pin provided, when they begin to notice
debris in and around the tube.
To clean the slim tube HE and dome:
1. Follow the instructions for removing the slim tube HE
from the hearing instrument. See the section
“Attaching and removing the slim tube HE”.
2. Use a damp cloth to clean the outside of the slim tube
HE and the dome.
3. Remove the dome from the slim tube HE.
4. Using the cleaning pin
provided in the kit,
gently insert the
cleaning pin where the
slim tube HE attaches to
the hearing instrument
and push the pin all the
way through the tube.
5. Attach the dome to the slim tube HE and attach the
slim tube HE to the hearing instrument.
Note: The slim tube HE and dome should never be rinsed or
submerged in water as water drops may become lodged in the
tube, block sound or damage the electrical components of the
hearing instrument.
