2) Introduction to the Comfort Digisystem
Thank you for choosing Comfort Digisystem. Our products are easy to use and give you crystal clear sound.
Before using the product, please read this manual carefully. The Comfort Digisystem products feature SecureStream
Technology – a unique, patented digital technology allowing eavesdrop-secure radio transfer in real time.
Comfort Digisystem Receiver DT10 — the world’s first digital mini receiver
The Comfort Digisystem Receiver DT10 is a digital mini receiver that you can easily connect to any hearing aid with a
standard three-pin Europlug audio shoe. The receiver weighs 0,05 oz (1,5 g) and is powered by the hearing instrument’s
battery. To minimize energy consumption, the mini receiver is equipped with an optional auto-sleep feature.
Together with existing microphones and receivers in the Comfort Digisystem assortment, the Receiver DT10 provides
clear speech perception. The Receiver DT10 is the world’s first mini receiver, taking full advantage of digital technology
in enabling outstanding sound reproduction.
The optional professional tool Programmer DT05 can be used to configure the Receiver DT10.
The Programmer DT05 also makes it easy to test the Receiver DT10 with or without a hearing instrument.
Push-button
For toggling between
different listening modes
and activating pairing mode.
3) Overview - Receiver DT10
Europlug
For connecting to the
audio shoe on a hearing
instrument or to
the socket on the
Programmer DT05.
4) Check the hearing instruments input
To be able to use the Receiver DT10, check if — and how
— the hearing instrument supports the use of a mini
receiver:
1. The hearing instrument must be equipped with an
audio shoe with a powered Europlug socket made for
mini receiver use. This connects the Receiver DT10
to the hearing instrument and also supplies the DT10
with power from the hearing instrument’s battery. The
received audio signal will then be transferred from the
Receiver DT10 to the hearing instrument through the
audio shoe.
2a. If the hearing instrument is equipped with a
Programmable DAI input (DPAI), programming of the
hearing instrument might be necessary (check with
audiologist or hearing instrument manufacturer). In
this case the push-button on the Receiver DT10 cannot
switch between the R and R+M modes. This is instead
done by using different listening programs in the hearing instrument.
Europlug
TIP! The volume of the Receiver DT10’s R and R+M mode
can be set individually by using the Programmer DT05.
This makes it possible to use the push-button as a simple
volume control in combination with a hearing instrument
with Programmable DAI input (DPAI).

2b. If the hearing instrument is equipped with a DAI
input (check with audiologist or hearing instrument
manufacturer), no programming of the hearing instrument is necessary. The Receiver DT10 works with the
Microphone (M) listening program on your hearing
instrument. By setting up the Receiver DT10 with the
Programmer DT05, the push-button on the Receiver
DT10 can be used to select the listening mode: Radio
only (R mode) or Radio + Hearing instrument microphone (R+M mode).
Europlug
5) Getting started
Connect the Receiver DT10 to the audio shoe on the
hearing instrument.
Check that the audio shoe is connected to the hearing
instrument according to the manufacturer’s instructions.
Make sure that the Receiver DT10 is fitted in the correct
manner and push the Euro-plug completely into the
socket of the audio shoe.
The Receiver DT10 is powered by the hearing instrument’s battery. Make sure that the battery is fresh. If you
are unsure, replace the battery.
Briefly press the push-button on the Receiver DT10 to
turn it on or off.
(If the Receiver DT10 has been programmed to the mode
Always on, it will start automatically when it’s connected
to the hearing instrument. The on/off function of the
push-button is then disabled.)
6) Acoustic indication, sound signals
The following is a description of the acoustic indications
(sound signals). The sound signals consist of various
combinations of two different tones: one high pitch tone
(1000 Hz) and one low pitch tone (500 Hz), and two different tone lengths.

7) Listening modes in the Receiver DT10
The available listening modes in the Receiver DT10
can be setup in different configurations:
R Default setting
R+M Setup with Programmer DT05
is necessary
R and R+M Setup with Programmer DT05
is necessary
The Programmer DT05 is used to configure and enable
or disable different listening modes in the Receiver
DT10. The push-button on the Receiver DT10 is used to
toggle between the activated listening modes.
It is also possible to disable the push-button completely.
8) Output for user with different input types and programs in the hearing instrument
Different hearing instrument electrical input types and available programs in the hearing instrument will result
in different output for the user. Output for the user is shown in the white sections of the charts below.

The chart below shows the output (what the user can hear) when Receiver DT10 listening mode R is enabled in
combination with different input types and programs in the HI.

* When using this setup in combination with Programmable DAI input (DPAI), the level of the two modes (R+M and R)
can be programmed individually to serve as a volume control.
Note! Difference in volume can occur
When using a hearing aid with Programmable DAI input (DPAI) and having both R and R+M modes in the Receiver DT10 enabled
there can be a difference in volume between the R and R+M modes even if the Receiver DT10 has been programmed with identical
output levels for the two modes. The reason for this difference is that the output level in the Receiver DT10 is affected by the input
impedance of the hearing instrument.
The difference in output level can vary between different hearing instruments - usually the output level will be slightly higher in the
R+M mode. An adjustment might be done with the Programmer DT05 in order to meet the users requirements.

The weights, dimensions, capacities, performance ratings and other data in
Comfort Audio’s brochures, prospectus, circulars, advertisements, price lists and
instructions sheets are mentioned only as general information. They are only approximate and shall not bind Comfort Audio.
Poor speech intelligibility
The distance between the transmitter and the receiver
may be too long. The range is around 50 feet
(15 meters).
The distance between the microphone and the talking
person may also be too long; move the microphone
closer to the talking person.
Try changing the channel/environment.
Poor range and interference
In some environments, such as in buildings with a lot of
concrete, iron or sheer metal structures, the range may
be reduced.
There may also be electronic equipment nearby causing
interference. Change the channel.
No sound
Check that the transmitter and the receiver are set to
the same channel.
Loud hissing noise
Check that the Comfort Digisystem units you are using
are paired together.
If Auto sleep is enabled, the Receiver DT10 goes into
sleep mode if there is no radio signal. But if another
radio signal (with the same frequency you are using) is
present, the Receiver DT10 might start again automatically. This could cause a loud hissing noise and that’s
why Auto sleep should be used with caution.
