DSpark Radio Transceiver Unit
The radio transceiver unit DSpark together with the docking unit DDoc ensures reliable wireless audio
transmission.
For basic configurations the DSpark can be used autonomously offering the most common functionalities for
discussion systems. This solution offers an inexpensive first step into the wireless world of conferencing
without loosing the opportunity for future system upgrading and expansion, either wired or wireless.
The radio transmission is based on the unique intelligent adaptive narrow band protocol (APRON) which
combines for the first time ever several wireless transmission security features within one single protocol
ensuring co-existence with Wi-Fi systems and resistance to mobile phones or Bluetooth emission, also
suppressing unwanted interception.
The wireless DIGIMIC provides also a multi-room solution, offering the possibility of using the same system
within one building in several rooms at the same time.
The DSpark is equipped with four independent antennas, receiving independently the individual signals of
each active microphone, providing a high audio quality and transmission reliability even under critical RF
congested environments.
The DSpark can also be wall mounted like shown in the next illustration. In this case also see HIGH POWER
in “Settings of DSpark” next chapter.

REGISTER
REGISTER can be opened (LED off) or closed (LED on).
Use REGISTER open (LED off) during setup.
During setup you switch on and register your units to the DSpark. The DSpark will automatically put all
recognized units into an internal list. This list will be expanded as long as the register function is open (LED
off).
To save this list close the Register (LED on). Once the register is closed no more units can be registered to
the DSpark. This function offers you the following opportunities:
1. The wireless system is now completely closed (like a wired one) and cannot be intercepted by any
other wireless DIGIMIC unit. This is important because to exclude interception you have to take out
the unit which are designed to work perfectly with the DIGIMIC wireless: DMic and DDoc.
2. This register function also enables to use multiple DIGIMIC wireless systems within one building by
simply assign your units to the DSpark of the corresponding room (please refer to page 26 for more
details)
Note: The list is stored automatically.
To delete the list press and hold button “register” for minimum 5 seconds. The corresponding LED
will flash two times to indicate that the list is deleted.
Note: You can exchange the battery pack and re-register the units which had already registered
even when the register is closed.
HIGH POWER
With this option the power of sending is increased in the case DSpark is used as desktop. When DSpark is
wall mounted, there is no need of increasing the output power.
PRIOrity mode
If a DChair unit is to be used, PRIO mode is available with this setting. Press button PRIO to enable this
option. Maximum 2 DChair units are supported as chairpersons at the same time. They will be identified
automatically. With 2 DChair units 2 active Delegate units DMic are possible at the same time.
This means:
0 DChair Æ max 4 active delegates’ are possible
1 DChair Æ max 3 active delegates’ are possible
2 DChair Æ max 2 active delegates’ are possible

DDoc Docking Unit
The docking unit DDoc transforms the delegate unit DMic into a wireless discussion unit, replacing the tasks
of a cable by its powerful rechargeable battery and the reliable and stable wireless communication protocol.
DMic and DChair are delivered with a cover to protect the contact bar.
Before using the DDoc the first time we recommend to check or charge the rechargeable batteries.
(please refer to page 23)
The transformation of the wired DIGIMIC delegate units is easily be done by unplugging the cable and sliding
the DMic on the docking station DDoc.
But before sliding the DMic on the docking station, it is necessary to remove the covering of the
contact bar on the rear side. This is done in the way shown below:
1. Turn the DMic upside down, if there is no microphone plugged in. We recommend
handling on a soft surface.
2. Press the two clips in the shown direction.
3. Turn the DMic on top, the covering should fall down.

The following chapter describes the operation with one DSpark in autonomous mode.
System startup
Before starting a conference all units have to be registered by the Radio Transceiver Unit DSpark. This is
easily done by just pressing the microphone key. Please ensure that the REGISTER LED is off. Successful
registration will cause the microphone ring and microphone button to flash twice.
DDoc Docking Unit
Before starting operation with the DIGIMIC wireless equipment make sure that the rechargeable batteries
inside the DDoc units are properly charged. Otherwise the battery pack has to be charged, either in the
DTray (Charging and transport tray for 10 DDoc) or with an external power supply.
For successful login status see table below.
Indication of battery status
There are three possibilities of checking the status of the rechargeable batteries:
1) In operation Æ by a Multicolor-LED in front of the docking station.
The Multicolor LED has different indication modes:
White – for a few seconds ready for operation
BLUE – flashing no reception, battery ok
BLUE – not flashing radio reception ok, battery ok
(more than 1h operation time)
OFF – permanent Switches off automatically after 30
sec for power saving
(standard operation mode)
RED – not flashing radio reception ok, battery low
RED – flashing no reception, battery low
(for less than 1h operation time)
Multicolor LED
Single operation mode
22
Easy rule to remember:
Mode flashing or permanent Æ receiving status
Color red or blue Æ status of rechargeable batteries
2) Not in operation Æ by a test key at the bottom of the battery pack.
Press and hold the blue test key with a peaked object or your fingernail. The green LEDs will then
indicate the current battery status in 20% increments.
For example:
Low battery power > 80% battery power Full battery, end of charging
LEDs

power Operating time
1 * 20% up to 4h
2 20 – 40% up to 8h
3 40 – 60% up to 12h
4 60 – 80% up to 16h
5 80 – 100% up to 20h
* If one LED is flashing, the battery is almost empty.
3) Not in operation Æ by charging in the DTray charging tray.
The status indication of the battery power is the same as shown above. The LED indication by charging the
docking unit in the DTray is permanently, so you don’t have to push the test key for this purpose.
Automatic switch off
The DDoc switches off automatically, if:
- the DMic will be disconnected from DDoc (immediately switching off)
- the battery pack is removed from the DDoc unit
- a switch off signal arrives from the DSpark (immediately switching off)
- there is no radio communication for 30 seconds (e.g. outside the radio range)
- the battery is empty
Note: If you switch off the DSpark radio transceiver unit, all registered DMic / DDoc units will switch
off immediately.

Charging of the battery pack
There are two options of charging the battery pack.
Charging via power supply
For a quick charging of a single unit an external power supply (05.0902) is provided. You do not need to
remove the battery pack from the DDoc. Just connect the plug to the connector of the DDoc.
Note: The discussion function of the unit is disabled when the external power supply is connected.
Charging with the external power supply is only possible if the unit is not in use.
Charging via DTray Charging Tray
For charging more than one battery pack an external Charging Unit DTray is provided. With DTray it is
possible to charge 10 units at once. First you have to remove the battery pack from DDoc.
Removing the battery pack
No tools are necessary to remove the battery pack. If not already done, separate the DMic unit from the
DDoc docking unit as shown below.
Note: This charging solution offers you the opportunity to leave all units on the tables in your
conference room. Just collect all batteries after the conference day to re-charge them.
You also can just exchange low batteries (during conference) with charged one’s offering the
possibility of an “unlimited” wireless conference period.

Multi room operation
The following chapter describes the operation in autonomous mode with more than one DSpark. Multi
operation mode is also available for slave mode in combination with DCen (wired central unit). The setup
procedure is the same.
With DIGIMIC wireless it is possible to handle parallel operation of different conferences in the immediate
vicinity. To enable a reliable operation each DSpark has to be configured with its own ID. Up to 5 radio
channel numbers (0 to 4) are possible.
Note: channel #0 is factory default
Multi room operation mode examples
a) Parallel operation with 3 DIGIMIC wireless systems in three conference rooms:
Room 1 Room 2 Room 3

Radio system number
For allocation of another channel number press the keys REGISTER and LS INTERN of the DSpark Radio
Transceiver Unit simultaneously. This will enter the configuration mode.
Figure 8
DSpark confirms this mode by blinking two times of all 4 LEDs (REGISTER + HIGH POWER + PRIO +
LS INTERN). The current radio channel number is displayed.
The pattern of the LEDs is shown in the table below:

Table 1
Now the user can specify the new logical radio number by setting the LEDs with the corresponding buttons
on or off. It is insignificant which LEDs are switched, or in what order this happens. Only the number of LEDs
lucent is relevant as input for the new radio system number.
Examples for valid input of radio system number 2:

Five seconds after pressing any button the configuration mode is finished. This is indicated by blinking two
times of all 4 LEDs (REGISTER + HIGH POWER + PRIO + LS INTERN). The new radio system number is
now saved will be used until this setting is changed again.
Also the primary status of the LEDs and the function of the buttons are restored. The new settings are
immediately effective; there is no need to switch DSpark on and off.
If no changes are made in configuration modus the current setting persists when leaving the configuration.
Therefore this procedure can be used to show the current setting of the radio system number.

Please make sure only one DSpark in your venue has activated the register function (register open –
LED OFF).
Please make sure that the preset of the several DSpark Radio Transceiver Units is like described above.
Open Register (LED OFF) on your first DSpark (Local radio channel number 0). Make sure other DSpark
have their Register closed (LED on). Place the desired number of units on the table and press the MIC
button one after each other.
Resetting of DDoc Docking Units
DSpark can reset all docking stations DDoc which are allocated to this DSpark (Radio Transceiver Unit) and
are in operating distance. Therefore press the inner buttons HIGH POWER and PRIO simultaneously for
about 5 seconds. The LEDs of HIGH POWER and PRIO are flashing for the time of deleting, but minimum
three times.
If you do this, all DDoc units will forget the room number they were tied to. This requires a new setup.
Allocation of DDoc Docking Units
To configure the DDoc units press and hold the MIC button for at least 4 seconds. This procedure is
indicated by flashing of the multi MIC-LED. The current radio channel number is reset. In this mode DDoc
searches for any DSpark Radio Transceiver Units. If one is recognized DDoc tries to log in. When successful
DDoc gets confirmation and stores the new radio channel number as default.
This will finish the configuration mode.
If there is no log-in possible DDoc will terminate the configuration mode after 30 seconds and then switch off.
When all microphones are working (successful login) a quick microphone test is recommended. Close the
Register (LED ON). After this you can go to the second room and perform the same procedure with a
DSpark assigned to the next room (local radio number 1).
