Delta – available for all!
With its innovative design and phenomenally small
size, Delta has forever changed people’s perception
of hearing aids from being “big, bulky and beige” to
being modern and fashionable. Delta has taken the
market by storm and established RITE (receiver-in-
the-ear) as a new category of hearing device.
Thanks to its new Micro Mold and broadband
fitting strategy, you can now fit Delta to any
configuration of hearing loss up to 80 dB HL.
Furthermore, with the addition of the new lower
priced Delta 4000, you now have 3 price options.
An exceptional ease of fit and amazing versatility
make Delta the most attractive micro BTE family on
the market. When people see it, they love it. You
can now fit Delta to 4 out of 5 people you see in
your clinic today. Just let them try it!
This guide takes you through the simple steps of
selecting, presenting, fitting, operating and selling
Delta. It will enable you to quickly get comfortable
with Delta and the many new possibilities it offers.

Fitting Delta
For the ideal cosmetic appearance and most comfortable fit
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 flush with
the skin, and the top of the amplifier should sit
horizontally on top of the ear, behind the pinna.

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 firm push.

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 difficult
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 finger 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 amplifier 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 flush with the client’s head. When looking
at your client face-to-face, you should not see the
speaker wire protrude/stick out.

19
If the speaker unit is too long, the amplifier 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 difficult
to achieve sufficient depth in the ear canal and the
device may fall out.
If the wire is not flush 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.

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.
