ing channels 1 – 5
3 Button "test switch" for testing the control channel
4 Control "audio level" for adjusting the sensitivity of
the audio inputs (8);
control range 500 mV – 10 V

8 Phono jacks "audio A in" and "audio B in" for the
audio inputs;
input sensitivity adjustable from 500 mV to 10 V
with the control "audio level" (4)
9 Low voltage jack "DC 7-30 V" for the power supply
with 7 – 30 V /max. 130 mA;
centre contact = positive pole;
required low voltage plug 5.5/2.1 mm (outside/
inside diameter)

2 Safety Notes

This unit corresponds to the directive for electromag-
netic compatibility 89/336/EEC.
The transmitter is suitable for indoor use only. Pro-
tect it against dripping water and splash water, high
air humidity, and extreme temperatures (admissible
ambient temperature range -10 °C to +55 °C).
For cleaning only use a dry, soft cloth, by no means
chemicals or water.
No liability for any damage will be accepted if the
transmitter is used for other purposes than orig-
inally intended, if it is not correctly connected or
operated or not repaired in an expert way.
If the transmitter is to be put out of operation defini-
tively, take it to a local recycling plant for a disposal
which is not harmful to the environment.

3 Applications
In combination with a 2.4 GHz receiver of the
MONACOR "AV-3...R" series, the transmitter AV-3040
TX serves for wireless transmission of video and
audio signals. For setting up a wireless video surveil-
lance system, merely a video camera and a monitor
are additionally required.
The transmission range largely depends on the
local conditions. Without any obstacles between the
transmitter and the receiver, the maximum range is
500 m. However, in buildings it is reduced to approx.
50 m by walls and ceilings, depending on their condi-
tion. By using an antenna with gain at the receiver,
the range can be increased many times over.
3.1 Approval
According to the R+TTE directive (Radio and Tele-
communication Technical Equipment), the approval
for the transmitter AV-3040TX is valid in the countries
of the European Union. For operation in countries
outside the EU, please contact your retailer or the
MONACOR subsidiary in the country where this unit
will be operated.

4 Operation

4.1 Placing the transmitter and the receiver
The highest reception quality is achieved when plac-
ing the antennas of the transmitter and the receiver in
parallel. For this purpose, after setting the unit into
operation, unfold the antenna (5) vertically and turn it
to optimum reception.
Practical experience has shown that an optimum
reception is achieved when placing the units at a
height of minimum 1.5 m to 2 m above the ground.
Prior to final mounting, a trial run is recommended as
the transmission quality can be substantially changed
by displacing the transmitter and the receiver by a few
centimetres only.
4.2 Connecting units
Prior to connecting any units or to changing any ex-
isting connections, switch off the transmitter and all
other units of the surveillance system.
1) Feed the video signal of the camera or the signal
source via a 75 Ω coaxial cable to the phono jack
"video in" (7). The level of the video signal must be
1 Vpp according to standard.
2) For audio transmission, feed the audio signal of
the camera or the signal source via a shielded
audio cable to the jack "audio A in" and, in case of
stereo transmission, additionally to the jack "audio
B in" (8).
3) If the receiver used is provided with a control
channel, it is possible to activate an optical or
acoustic signal device or another additional unit
connected to the receiver via this channel (e. g.
