Fitting Delta

For the ideal cosmetic appearance and most comfortable fi t
with Delta please consider the following:

• Selection of correct speaker unit length

• Selection of correct dome size

• Correct insertion of speaker in the ear

• Use of the ear grip, if necessary

11

Selecting Speaker Unit Length

The speaker unit is available in four lengths and in
left/right versions. No. 1 is the shortest and no. 4 is
the longest. The lengths most commonly used are 2
and 3.

The speaker should sit comfortably and hidden
in the ear canal. The wire should be fl ush with
the skin, and the top of the amplifi er should sit
horizontally on top of the ear, behind the pinna.

1 2 3 4

12

1

2

3

4

Use the measuring tool to select the correct speaker
unit length. Place the measuring tool on the ear,
as shown. Choose the length corresponding to the
size-marking on the measuring tool at the top of the
ear canal opening.

13

Attaching the speaker unit

Slide the speaker unit into the plug. Slide only in
the direction of the plug. Do not force the speaker
unit plug downward. When the plug is in place,
give it a fi rm push.

123

14

Replacing the speaker unit

Gently pull off the speaker unit. Pull only in the
direction of the plug. Do not pull upwards as this
may damage the plug.

&

&

15

Attaching the ear grip

The ear grip should be used to obtain a more secure
retention in the ear canal. It is available in one
version for both left and right ears. Insert the ear
grip into the slot in the receiver.

Important: Pull the ear grip through the slot until
the top of the grip is positioned inside the slot and
pointing away from the dome, as illustrated. If it is
incorrectly inserted, the ear grip might be diffi cult
to place in the concha.

&

&

16

If the ear grip seems too long in the concha, you
may cut/trim it to the desired length. Take care not
to leave a sharp and pointy end when cutting as
this can cause irritation in the ear.

Taking off the ear grip

17

Use a fi nger nail to dislodge the ear grip from the
slot then push it through from the other side.

18

Inserting and placing the device on the ear

1. Insert the speaker with an attached dome/Micro
Mold into the ear canal.

2. Place the amplifi er behind the ear.

The speaker unit with the dome/Micro Mold should
be placed far enough into the ear so that the speaker
wire lies fl ush with the client’s head. When looking
at your client face-to-face, you should not see the
speaker wire protrude/stick out.

2

1

19

If the speaker unit is too long, the amplifi er will sit
too low behind the ear and the microphones will
point vertically instead of horizontally. Also the
wire will protrude, as pictured. Proper microphone
positioning is essential for optimal performance of
the directionality.

If the speaker unit is too short, it will be diffi cult
to achieve suffi cient depth in the ear canal and the
device may fall out.

If the wire is not fl ush with the skin, check that the
insertion depth is adequate. Choose another dome
size if the speaker unit needs to move further in the
ear canal.

Speaker unit too long

Speaker unit too short

• Use a hair dryer or hot air blower at low heat

setting

• Heat for a short time – a matter of seconds

• Bend into desired shape and hold in place

until wire is cooled off.

• Do not use excessive heat, as this could

damage the speaker unit.

20

Manipulating the speaker unit

21

“S” Curve

• To add length to the speaker, straighten out, or
elongate the S portion of the speaker wire.

Bend into the Canal

• Adjust this bend to stop the wire from bowing
out from the side of the client’s ear, or to increase
the depth of speaker insertion.

25

The Open dome is available in three different sizes:
6 mm, 8 mm and 10 mm. The most commonly used
is the medium sized 8 mm dome. The Plus dome is
available in one size.

The Open dome is suitable for hearing losses up to
70 dB in the high frequencies and is the best option
for most users. The Plus dome allows more mid­frequency gain and extends the fi tting range to 80
dB HL in the high frequencies. It is suitable if the
user wants more volume or more mid-frequency
gain. Genie will automatically prescribe Open or
Plus dome.

The oval tip of the Plus dome should always be
placed on the speaker unit as illustrated:

The dome should sit comfortably in the ear canal
and support and hold the speaker. Use an otoscope
to inspect client’s ear canal to determine dome size.

26

Choosing the correct dome size

If the dome is too small, the speaker will not be
securely positioned in the ear canal and it may also
itch or tickle in the ear canal. If the dome is too big,
it will be diffi cult to get insert deeply enough into
the ear canal or it may collapse in the ear canal and
be uncomfortable to wear.

Dome too small

Dome too big

27

Remove the old dome using your fi nger nails. Push
the new dome onto the speaker. Give it a push to
secure it safely.

123

Changing the dome

28

Micro Mold

The Micro Mold is an acrylic custom solution that
can be used instead of a dome.
Micro Molds are produced from a traditional, deep
impression.
The adaptor clearly indicates R/L color marking.

Adaptor

WaxStop

Up/Down Indicator

29

Micro Molds can be made with tube-shaped vents,
as in traditional ear molds, but the length is shorter
than standard vents. Therefore, the Micro Mold
vent effect is much larger than its actual diameter.
Genie prescribes the vent size, when Micro Mold
is selected.

Micro Molds can also be used and selected in Genie
for mild and moderate high frequency hearing
losses, where open domes are prescribed. In these
cases, Micro Molds can be ordered with larger
collection vents for maximum occlusion relief.

Attaching the Micro Mold

When fi tting Delta with Micro Molds follow the
instructions below:

1. Find the correct speaker unit length and attach it
to the amplifi er
(see Selecting speaker unit length).

2. Carefully insert the receiver into the Micro Mold
and click the Micro Mold into place.

3. The Micro Mold can rotate axially to ensure
maximum comfort. Before placing the Micro
Mold in the ear, turn the Micro Mold until the
up/down indicator points upwards.

31

Note:
Take care not to insert the speaker unit into the
Micro Mold at an angle. Unless it is inserted
correctly, the speaker will not lock into place.
When placed correctly, you should hear the speaker
snap into place with a “click”. Only a little pressure
is required.

Don’t force the two units together!

32

33

The Micro Mold should not be detached from
the speaker without the Micro Mold tool.

When detaching the Micro Mold follow the
instructions below:

1. Remove the WaxStop.

2. Place the Micro Mold in the tool as
illustrated making sure that the cross in the
adaptor is aligned with the tap of the tool.

3. Carefully press the tool to release the
speaker unit.

4. Now remove the Micro Mold from the
speaker unit.

Taking off the Micro Mold

34

Fitting Delta in Genie

When connecting Delta to Genie 8, the various
prescriptions will be based on the hearing loss type:

1. Mild/moderate high frequency hearing loss

2. Moderate, severe low frequency hearing loss and
conductive hearing loss.

The prescriptions affect the

• amplifi cation strategy

• disposable dome type, when domes are selected

• Micro Mold vent size, when Micro Molds are
selected

The fi tting fl ow remains the same.

35

Amplifi cation strategies

Mild/moderate high frequency
hearing losses:

Genie prescribes the Clarity rationale.
The Clarity rationale is focused in the high
frequencies. The overall goal is to enhance speech
clarity and improve intelligibility in noise.

Moderate, severe low frequency hearing
loss including conductive hearing losses:

Genie prescribes the VAC rationale.
VAC (Voice Aligned Compression) provides
amplifi cation in the low, mid and high frequencies.
The overall goal is loudness normalization.

36

Ear pieces

You can select disposable domes or customized
Micro Molds when fi tting Delta.

Open dome and Plus dome

When selecting domes, Genie prescribes Open
dome or Plus dome based on the prescribed high
frequency gain.

Domes are suitable for mild and moderate high
frequency and broadband hearing losses within the
illustrated fi tting ranges.

1. How often should the Dome be
changed?

The dome should be replaced whenever needed.
For most users, this will be once every one or two
months. The user should receive a pack of domes
with the device. The dome is part of the protection
system of the speaker unit against ear wax.
Frequent replacement will ensure long life.

2. How frequently should the WaxStop
in the Micro Mold be changed?

The WaxStop should be changed whenever needed.
For most users, this will be once a month or if there
is no sound in the device.
See the WaxStop package for replacement
instructions.

3. When should I change the NoWax in

the speaker unit?

Visually inspect the NoWax. If it is clogged,
or there is no sound in the device, replace the
NoWax fi lter. See the NoWax package for
replacement instructions.
The NoWax should be changed only by the hearing
care professional.

FAQ

63

4. What is the difference between the
two wax fi lter systems for Micro Mold
clients?

NoWax fi ts into the Delta speaker and is changed
only by the hearing care professional.
WaxStop fi lters fi t into the Micro Mold. The
WaxStop is much smaller than the NoWax. The
client will need to purchase only the WaxStop fi lters.

5. How frequently should the speaker

unit be changed?

The speaker unit is designed to function for a
long time (several years), if it is cleaned properly,
always used with a dome or Micro Mold, and never
removed. The speaker unit is an integral part of the
device and should only be removed or replaced if
broken. The user should not remove the speaker
unit.

6. Can I change the shell colors in
my offi ce?

If you follow the shell change instruction in this
guide, there is no risk when changing the shells.

7. How can I ensure that the battery
doors are suffi ciently opened when
the devices are not being used?

Demonstrate how Delta only fi ts perfectly in the
instrument case when the battery doors are totally
open to ensure disconnection and ventilation.

64

8. What if the dome comes off in the ear
canal?

Gently take it out, if possible by help of a spouse or
relative.
The dome is made of a soft, medically approved
material, which is not harmful in any way.
However, to prevent this situation, remember to
change domes frequently, as their natural elasticity
will disappear over time.
