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.

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.

different listening modes
and activating pairing mode.

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.

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).

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.
