AV Transmission System
GB
Please read these operating instructions carefully
prior to operating the unit and keep them for later
reference.

Applications
This wireless transmission system allows to trans-
mit a video signal in CVBS format (composite) and
two audio channels. The digital procedure offers a
reliable, encrypted transmission up to a range of
80 m outdoors or 30 m indoors.
1.1 Conformity and Approval
Herewith, MONACOR INTERNATIONAL declare
that the transmission system DVA-2400SET is
in accordance with the basic requirements and
the other relevant regulations of the directive
1999/5/EC. The declaration of conformity is avail-
able on request from MONACOR INTERNATIONAL.
The transmission system operates in the 2.4 GHz
range and is licence-free and generally approved
for operation in EU and EFTA countries.

Safety Notes
The units (transmitter, receiver and power supply
units) correspond to all relevant directives of the
EU and are therefore marked with
WARNING The power supply units are supplied
with
hazardous
Leave servicing to skilled personnel
only. Inexpert handling or modifica-
tion of the power supply units may
cause an electric shock hazard.
It is essential to observe the following items:
G
The units are suitable for indoor use only. Protect
them against dripping water and splash
water, high air humidity and heat (admissi-
ble ambient temperature range 0 – 40 °C).
G
Do not set the transmission system into
operation, and immediately disconnect
the corresponding power supply unit from
the mains socket if
1. there is visible damage to one of the
units,
2. a defect might have occurred after a
drop or similar accident,
3. malfunctions occur.
The units must in any case be repaired by
skilled personnel.
G
For cleaning only use a dry, soft cloth,
never use chemicals or water.
G
No guarantee claims for the units and no
liability for any resulting personal dam-
age or material damage will be accepted
if the units are used for other purposes
than originally intended, if they are not
correctly connected or operated, or not
repaired in an expert way.
DVA-2400 SET
If the units are to be put out of operation
definitively, take them to a local recycling
plant for a disposal which is not harmful to
the environment.

Mounting and Connection
Transmitter and receiver may be set up or be fixed
e. g. to a wall via the cross-shaped openings at the
bottom of the housing by means of wall hooks or
screws. Make sure that the screw head does not
protrude too far into the housing; the PCB may be
damaged. The air vents of the housing must not be
covered.
Only make or change any connections with the
units switched off.
1) Connect the video source to the jack VIDEO (4)
of the TRANSMITTER.
2) Connect an audio source with line level to the
jacks AUDIO (3)
(for stereo signals: L = left channel, R = right
channel).
3) Connect the unit for processing the signals (e. g.
monitor or video recorder) to the jacks VIDEO
and AUDIO of the RECEIVER.
4) Screw the antennas (1) provided onto the jack
ANT (2) of the transmitter and receiver respec-
tively. Align both antennas in a vertical position.
.
5) Connect the plug-in power supply units provided
to the low voltage jacks "9 V " (5) and to a
mains
voltage.
mains socket (230 V~ / 50 Hz).
Caution: Never set the TRANSMITTER into
operation without the antenna provided. It may
be overloaded.
3.1 Receiving antenna DVA-2400ANT
To increase the range, the antenna DVA-2400ANT
is available with a gain of 18 dBi. It is also suitable
for outdoor mounting. Connect the antenna via the
cable supplied to the jack ANT (2) of the
RECEIVER and align it to the antenna of the trans-
mitter.
The outdoor mounting has to be made by an
expert who is familiar with the regulations of light-
ning protection and makes sure that the antenna
mast is earthed.

Operation
To switch on the units, set the switches POWER (6)
to position ON; the POWER LED (7) lights up.
After operation switch off the units with the
POWER switch. If the units are not in use for a
longer period of time, disconnect the power supply
units from the socket because they have a low
power consumption even with the unit switched off.

The units are factory-set so that they automati-
cally build up the radio connection towards each
other after switching-on. The LEDs LINK (8) extin-
guish shortly after switching-on and light up again
when the connection exists. In case the connection
is missing, the connected monitor shows "NO SIG-
NAL" (e. g. when the distance between transmitter
and receiver is too long). When there is a connec-
tion but no video signal, "NO VIDEO SIGNAL"
appears.
4.1 Setting up a new connection
For setting up a new wireless connection (e. g.
when several sets are used in parallel):
1) Keep the button PAIR (9) on the receiver
pressed for 4 s. The LED LINK (8) flashes and
the connected monitor shows: "Please press
pairing button of TX device".
2) Within the next 30 s keep the button PAIR on the
transmitter pressed for 4 s. The LED LINK
flashes and "Pairing OK, Save data" appears.
The connection is memorized and the LED LINK
lights up.
If the LED extinguishes and "Pairing fail [...]"
appears, the connection set-up has failed. Reduce
the distance between transmitter and receiver or
align the antennas in a different way, if required.
Then repeat the operating steps.
