Important information
Hearing instruments should not be fitted with domes/wax
protection system when used by patients with perforated
eardrums, inflamed ear canals or otherwise exposed
middle ear cavities. In these cases, we recommend the
use of a custom earpiece.
In the unlikely case that any part of the system remains
in the ear canal, it is strongly recommended to consult a
medical specialist for safe removal.
•The dome should be changed every three months or when
it becomes stiff or brittle. This is to prevent the dome from
detaching from the receiver sound outlet during insertion
into or removal from the ear.
•Changes or modifications made to this equipment not
expressly approved by Phonak are not allowed.
Thank you for choosing a Phonak Receiver-In-Canal (RIC)
product, designed to provide comfortable, flexible fittings
for your patients.
These assembly instructions provide you with a straight-forward
approach to fitting Phonak RIC hearing instruments for
long-term satisfaction.
Please note that all SDS 4.0 components
are only compatible with Phonak Audéo™
Marvel devices.

1. Position your head at the same horizontal level as the patient’s
head so you are looking straight into the patient’s ear. (a)
2. Hold the measurement tool with the appropriate blue or
red color code marking so your thumb is placed on the
colored area. (b)
3. Place the measurement tool on the top of the ear. Keep the
lines on the measurement tool horizontal. (b)
4. Choose the number (0, 1, 2, or 3) on the measurement tool
which is closest to the top of the opening of the ear canal.
In this example, 0 would be the most accurate choice. (c)
5. For binaural fittings, repeat process on the opposite ear.
Note:
It is important to measure both ears for a binaural fitting since right and
left ear sizes can vary and may require different receiver lengths.

Dome size
Perform an otoscopic examination of your patient’s ear canal. Based on the
examination, choose a dome size diameter and length suitable for the ear canal.
The dome should fit snugly and comfortably into the opening of the patient’s ear
canal, shown in the figure, and help to retain the receiver inside.
*There are no coupling instructions for cShell as it is pre-assembled. Receiver with cShell can only be exchanged by Phonak.

Removing the retention
We recommend using the retention piece for a
more stable positioning of the receiver in the ear
canal. It can easily be pre-shaped to the concha
by sliding it over a solid edge.
Attaching / removing the retention to/ from the receiver
1. Hold receiver rmly with one hand.
1. Hold the receiver rmly in one
hand with the receiver name
(e.g. 0M) facing upwards. With
the other hand hold the retention
at the base of the lament.
Attaching the retention
2. Slide the retention over the
receiver spout until you feel it
click into place. The receiver
name should still be clearly visible.
2. Slide the retention forwards over
the receiver spout.

7
Attaching the dome to the receiver
1. Hold the receiver in one hand and the dome in
the other hand.
2. Slide the dome over the receiver spout.
You will feel the dome “click” into place.
In very rare cases, the dome can remain in the
ear canal when removing the receiver from the
ear. In the unlikely case that any parts remain
in the ear canal, it is strongly recommended to
see a medical specialist for safe removal.

Attaching the SlimTip to the receiver
1. Slide the receiver into the sleeve of the handling
tool, ensure the receiver label (e.g. 0M) is visible
and facing upwards, and the receiver cable is
extending upwards. Note that the tool has three
dierent sized sleeves to accommodate S, M and
P receiver housings.
3. Gently insert the receiver spout into the SlimTip Link
until you feel it click into place securely.
2. Hold the SlimTip rmly with one hand, with the
other hand insert the receiver using the handling
tool. Note that the printed label on the SlimTip
faces the opposite direction to the receiver label.
4. Gently slide the tool away from the receiver.

9
Removing the SlimTip from the receiver
1. Hold the SlimTip firmly in one hand.
3. Detach the receiver from the SlimTip
with a firm pull.
2. With the other hand, firmly grip the receiver at the
base of the cable.
Note:
There is no tool for removing SDS 4.0 receivers
from the SlimTip. Please do not insert any tool
into the SlimTip opening to push the receiver
out; doing so may cause damage to the receiver.

10
How to exchange the receiver
1. Align the 3 pins with the 3 sockets in the hearing aid.
Gently slide the cable into the sockets until securely
in place.
1. Use the pin removal tool to push the pin (circled).
2. Push the pin back into place to lock the receiver
into position.
2. Gently pull the receiver away from the hearing aid.
Do not twist the receiver when removing. Twisting
could cause damage to the wires.

All domes are designed as the first line of defense against
wax. At the tip of each dome is a small shield that protects
the sound inlet (indicated by the green arrow). Domes
should be changed at least every three months or when
they become stiff or brittle. The client should wipe the
dome daily with a dry tissue.
Earpieces should be wiped daily with a dry tissue. We suggest
checking the tip of the ear piece regularly and exchanging the
wax filter when necessary.
