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 1,5 gram 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.

Check the hearing instrument’s 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.

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 Micro-
phone (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).
