Earset DE-10
Introduction of the Comfort Digisystem
Thank you for choosing the Comfort Digisystem. The
products are easy to use, with or without hearing aid.
Before using the product, please read this manual care-
fully.
The receiver Earset DE-10 receives signals digitally which
results in crystal clear sound.
The Comfort Digisystem is tted with SecureStream
Technology – a special kind of digital technology allowing
eavesdrop-secure radio transfer in real time.
Presenting the Earset DE-10
The Earset DE-10 is a small, exible receiver which is
attached directly to the ear, usable with or without all-in-
the-ear – hearing aids. The receiver can be used on both
right and left ear.
It suits users with high demands for nicely designed and
discreet products. Furthermore, the radio signal is en-
crypted, making it impossible to overhear what is being
said.

Switch on the receiver by pressing the On/Off-button for
around 2 seconds until the function indicator’s green light
switches off.
The DE-10 is attached to the ear with the earloop.

volume can seriously damage your hearing.
DE-10’s earloop can be turned around its fastening so
that the loudspeaker can be brought to the ear canal. The
earloop should not be bent.

Settings
As the DE-10 does not have a display/menu, the unit’s
functions are controlled by means of the pairing button.
The current function is shown by the function indicator.

three other functions can be activated.
To do this, press the pairing button and hold it immedi-
ately after starting up the unit for 2 seconds.
A selected function can always be cancelled by switching
of the DE-10 and starting it up again.

and Channels
). To choose a channel, press the pairing
button briey the number of times corresponding to the
desired channel (1x for channel 1, 2x for channel 2 etc.)
After 2 seconds, the selected channel is shown by the
same number of green ashes of the function indicator.

Pair
Earset DE-10 must be paired using the pairing button,
see section
Pairing (via pairing button)
.
Pairing
To use a receiver and transmitter together, they must be
paired. All transmitters and receivers are default paired
at the factory and will work together.
NB! To prevent eavesdropping, a new code key must be
generated and transmitted between the units by pairing.
Transmitting/receiving of pairing information along with a
new code can be performed from any Comfort Digisystem
unit with a display.
To pair units without a display, see sections
Pairing (via
pairing button)
and
Pairing (Connector DT-10)
. Pairing
information or a new code key can be received by several
activated units.
Pairing (via menu)
1. Choose Communication - Pair
2. Select Receive info on one unit. Ready to receive
pairing info is shown in the display.
3. Select New code on the other unit; select Yes.
4. Generate new code and send info? is shown in the
display. Select Yes (Now both the channel and the
coding information have been sent, and sound
transfer is eavesdrop-secure).
5. To pair another unit into your coded system, select
Send info instead on one of your paired units.
11
Earset DE-10
Pairing (via pairing button)
(The only way of pairing units without a display, with the pairing
button)
You can activate the Pairing function via the pairing button.
1. One brief press of the button opens the
Pairing
menu.
2. Two brief presses activate the Send info function.
3. One long press activates the Receive info function.
Pairing (Connector DT-10)
The connector cannot send information, only receive it.
1. To activate the position Receive info, the connector
must be in operation (position I or II) and connected to
an operating hearing aid.
2. The selector is then quickly moved to position 0 and
back to the operating position (I or II). The connector
can now receive pairing info.
3. If no info is received by the connector, after a short
time this returns automatically to the previous
setting.
Units with both transmitters and receivers built in
Comfort Digisystem units with both transmitters and receivers
built-in can be paired separately.
When opening the pairing menu, choose the concerning unit
(transmitter/receiver). In units with both transmitters and re-
ceivers, the pairing button controls the transmitter.
The transmitter and receiver are paired separately in these
units. The code key is always the same for the transmitter and
the receiver when these are built-in in the same unit.
The easiest way to get the same code key in the whole Digisys-
tem is to generate a new code key from the combined unit; in
that way the built-in receiver gets the same code as the rest of
the system.

Radio Range and Channels
Digisystem transmitters and receivers have built-in
antennas. The radio range between the units is around
30 meters. However, this may vary, depending on the
particular environment you are in. Like all radio systems,
Comfort Digisystem communicates on specic channels.
If you use two transmitters on the same or neighboring
channels, there may be interferences. Other electronic
equipment can also interfere with radio transmissions.
In most European countries, channels 1-3 (863.250 –
864.750 MHz) may be used for hearing products. How-
ever, you should always check with the frequency assign-
ment authority in your own country which channels are
free to use and which require a licence.

Trouble shooting
The transmitter and receiver do not start
Charge the transmitter and receiver. Remember to press
the On/Off-button for 2 seconds to switch the unit on.
Check that the charger is connected to the socket.
Poor Speech intelligibility
The distance between the transmitter and the receiver
may be too long. The range is around 30 meters. The
distance between the microphone and the person talking
may also be too long; move the microphone nearer to the
talking person. Try to change channel/environment.
Poor range and interference
In some environments, e.g. buildings with a lot of con-
crete, iron or sheer metal structures, the range may be
reduced. There may also be electronic equipment nearby
causing interference. Change channel.
No sound
Check that the transmitter and receiver are set to the
same channel.
Loud hissing noise
Check that the units are paired.
