Microphone DM80
Introduction to the Comfort Digisystem
Thank you for choosing Comfort Digisystem.
The products are easy to use, whether you use a hearing aid or not.
Before using the product, please read this User Manual carefully.
Using the Microphone DM80 transmitter, the signal is transferred digitally,
resulting in excellent, clear sound.
Comfort Digisystem is fitted with SecureStream Technology - a type of digital
technology allowing eavesdrop-secure radio transfer in real time.
Presenting the Microphone DM80
A microphone that not only serves as a conference micro-phone, but can also
be connected to telephones. The DM80 can be connected via Bluetooth to a
mobile phone/portable phone, and the microphone can be connected via a
cable to a telephone using a 2.5 mm headset socket.
The DM80's built-in microphones are used to speak into, while incoming
sound from the telephone is transmitted in a wireless, interception-secure
link to any Digisystem receiver.
The DM80 has both an omnidirectional microphone and a directional micro-
phone for use in environments with more disruptive background noise. The
large, practical answering button can be used to answer calls with a Blue-
tooth connection, even if you have your phone in your pocket, for example.

Back (relates to both the main menu and submenus)
Here you can choose to return to the menu and to the main display
Communication
Channel
To use the receiver and the transmitter together, they must be set to the same
channel. The transmitter and receiver are set to the default channel by the
manufacturer.
This does not apply to units with both sender and receiver. In this case the
transmitter/receiver are adjusted as described in chapter
Radio range and
Channels
.
Change channel:
1. Choose Channel in the menu.
2. Choose transmitter or receiver (this applies only to
units with both transmitter and receiver).
3. Select a new channel using the menu control.
Channel information is also given when the units are paired.
Channels 1, 2 and 3 are free channels in most European countries that do not
require a licence. Under Extended more channels can be selected, but these
usually require a licence – see the section
Radio Range and Channels
.
FFC (Free Frequency Check) indicates in green the suitable frequencies for
the specific environment. Please note! Switch off your other Digisystem trans-
mitters for correct result.
Pair
To use a receiver and transmitter together, they must be paired. All trans-mit-
ters and receivers are default paired at the factory and will work together.
NB! To prevent eavesdropping, a new code key must be generated and trans-
mitted between the units by pairing.
If the message Channel combination not possible appears during pairing,
this indicates that the selected frequency is outside the frequency range
within which the unit can transmit/receive. Check possible channels in the
Communication - Channel menu.

Microphone DM80
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)
for
more information. 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.
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.
Cancel pairing function
When activating the pairing function, it is possible to cancel this function by
pressing the answering button. When you chose the BT pairing function and
you do not continue, the pairing function is canceled after 5 minutes.
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 receivers, 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.

Microphone DM80
The easiest way to get the same code key in the whole Digisystem 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.
Bluetooth
Here you can activate Bluetooth to be able to pair the Microphone DM80 with
a telephone or mobile.
For detailed user information, see chapter
More Functions - Bluetooth
.
Telephone
Under the Telephone menu you can configure the DM80 to function as a
telephone headset.
Connect the DM80 to the telephone's multifunction socket via the headset
cable supplied.
Please note: When the headset cable is connected to the DM80, the built-in
microphone is switched off and only works when a phone call is made.
To activate the telephone function, enter the menu under Communication -
Phone - Enable (Press shortly the menu control; a green tick shows that the
telephone function was activated and a small telephone shows in the down
left corner of the main display.
Use your telephone as usual; the voice of the person you are talking to is
transferred via the cable to the DM80; from there it is sent wirelessly to your
Digisystem receiver.
