with 7 – 30 V /max. 130 mA;
centre contact = positive pole;
required low voltage plug 5.5/2.1 mm (outside/
inside diameter)
2 Important Notes
The transmitter corresponds to all required directives
of the EU and is therefore marked with
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 guarantee claims for the transmitter and no lia-
bility for any resulting personal damage or material
damage will be accepted if the transmitter is used
for other purposes than originally 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
definitively, 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 Conformity and Approval

Herewith, MONACOR INTERNATIONAL declare that
the transmitter AV-3040TX is in accordance with
the basic requirements and the other relevant
regulations of the directive 1995/5/EC. The declara-
tion of conformity can be found in the Internet
via the MONACOR INTERNATIONAL home page
(www.monacor.com).
The transmitter is licence-free and generally
approved for operation in EU and EFTA countries.
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).
