-Dedicated for groups with one guide, for excursions and production hall
tours.
-This mode allows the activity of only one transmitter.
-The operator of the transmitter may enable two-directional communication
by switching the (10) switch from “m” to “s”
-Only one user of the receiver may speak in the given time.
2.2 Communication mode “Teaching”
-Dedicated for groups with two guides and for participants of the lecture/
presentation.
-This mode allows for activity of two transmitters at the same channel.
-One transmitter must be set to “m” (master) (10), and the other must be
set to “s” (slave).
-The users of transmitters conduct free talk, which is broadcasted to users
of receivers.
-In order to allow asking questions, or for short statements, the user of the
transmitter, which is set (10) to “s” must mute out using the talk/mute
switch (5) or by plugging out the headset from the
headphones/microphone port.
-Only one user of the receiver may talk in the given time.
?

2.3 Communication mode “Discussing”
-Dedicated for discussion groups.
-This communication mode allows activity of more than 2 transmitters on
the same channel.

disabled.
-The users of transmitters may communicate freely, regardless of the
position of the (10) switch of the transmitter.
3. Handling of the OTG-200 system
Committing to the presented sequence of launching the OTG-200 system
is crucial for avoiding unwanted errors.
➔In the transmitter which will be used as the main one (master), set the
switch (10) to the “m” position.
➔Next, turn the transmitter on by pressing and holding the power button
(9) and the DOWN button (8) for 3 seconds.
This action allows for selection of the desired communication mode (see point 2.
Available communication modes in OTG-200 system).
➔Using UP/DOWN (8) buttons scroll through the available modes. Press the
power button (9) to confirm the selected communication mode.
➔Turn the transmitter off by pressing and holding the power button (9).
This way, the transmitter memorises the selected communication mode. Now
you can start pairing the devices.
➔Turn the transmitter (master) on again, by pressing and holding for 3
seconds both the calling button (6) and the power button (9).
➔The channel selection shall be started within 3 seconds after powering up
the transmitter, with UP/DOWN (8) buttons. The selected channel shall be
confirmed with the power button (9) or by waiting for 3 seconds for
automatic confirmation. In this way, the pairing mode has been activated.
Pairing of devices is important because it allows free transition of the receivers
and the second transmitter to the same communication mode as the master
transmitter, and gives the users access to “advanced settings”.
➔Turn on the receivers (each receiver shall be turned on one after another)
by pressing and holding the power button (9) for 3 seconds.

The receivers pair with the transmitter automatically, by adjusting to the same
channel on which the master transmitter is working. The communication mode
will show up on the receiver’s screen after pairing the receivers. The screen of
the transmitter will display the number of paired receivers.
➔After turning on all of the receivers, it is time to pair the second
transmitter.
If a “guiding” communication mode has been selected, the pairing of second
transmitter may be skipped. If the “teaching” communication mode has been
selected, it is important to set the switch of the second transmitter to the “m”
position.
➔Turn the second transmitter on, by pressing and holding down both DOWN
button (8) and power button (9) for 3 seconds.
➔With UP/DOWN buttons (8) scroll through the available communication
modes. Press the power button (9) in order to confirm the desired
communication mode.
Make sure that the selected communication mode is the same as in the first
transmitter (master).
➔Turn the transmitter off by pressing and holding the power button (9).
➔Turn the transmitter on again, by pressing and holding for 3 seconds both
the calling button (6) and the power button (9).
➔Using UP/DOWN (8) set the same channel as in the first transmitter
(master).
After a while, the transmitter’s screen will display a number of paired receivers
(the same as in the first transmitter). This means that the whole operation has
been performed correctly.
➔Now, the pairing mode in transmitters shall be turned off, by pressing the
calling button (6).
After connecting the accessories (headsets, headphones) the transmitters and
receivers are ready for work.
Synchronisation of OTG-200 system.
The OTG-200 system allows synchronisation of the transmitter with receivers
without the necessity to pair the devices. This allows standard communication
between devices, which is offered by the selected communication mode (see
point 2), however the “advanced settings” remain disabled.
➔Turn the transmitter on, by pressing and holding down both DOWN button
(8) and power button (9) for 3 seconds.
➔With buttons UP/DOWN (8) scroll through the available modes. Press the
power button (9) to confirm the selected communication mode.
➔Turn the transmitter off by pressing and holding the power button (9).
➔Turn the transmitter on again (master) by pressing and holding both the
talk/mute button (5) and power button (9) for 3 seconds.
➔Channel selection shall be started within 3 second since powering up the
transmitter, with buttons UP/DOWN (8). The selected channel shall be
confirmed with the power button (9) or by waiting for 3 seconds for

automatic confirmation. In this way, the synchronisation has been
activated.
➔Turn the receivers on (each receiver shall be turned on one after another)
by pressing and holding the power button (9) for 3 seconds.
The receiver will automatically synchronise with the transmitter by setting the
same channel and communication mode.
➔After turning on all required receivers, the synchronisation mode shall be
turned off by pressing the talk/mute button (6).
➔In order to use the second transmitter in the selected communication
mode it shall be turned on by pressing and holding both the DOWN button
(8) and power button (9) for 3 seconds.
➔Using the UP/DOWN buttons (8) the same communication mode as in the
first transmitter shall be selected. Confirm the selection with the power
button (9).
➔Using the UP/DOWN buttons (8) set the same channel on which the first
transmitter and receivers are working.
OMNITourguide System has been synchronised.
4. “Advanced settings” (available after “pairing”)
4.1 Roll-call signal
Allows the management of the state of the group of receivers.
Press the calling button (6) in the transmitter, while it is turned on.

If the receivers are within the range of the “roll-call” signal, their diodes
(3) will start to blink quickly for 10 seconds.
The number of the receivers which are currently within range, displayed
on the transmitter screen will be rising until the signal ends.
It shall be checked if the number of receivers within range is the same as
the number of receivers which shall be in range of the transmitter.
To turn off the roll-call signal, press the calling button (6) again.

button (5) starts blinking red. The “Gather” symbol appears on the
screen.
In order to turn off the Calling signal, press the calling button (6) in the
transmitter and the alarm turn-off button (6) in the receivers.
4.3 Out-of-range alarm
If the user of the receiver is not receiving the signal from the transmitter for 3
minutes, he receives an alarm.
The receiver starts vibrating, and the talk/mute button (5) starts blinking
red. The screen of the receiver displays an “Out of range” symbol.
The alarm can be turned off by getting the receiver into the area of the
transmitter’s range or by pressing the alarm turn-off button (6) in the
receiver.
