4 Operation

4.1 Placing the transmitter and the receiver
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 Mounting
1
A 6.3 mm ( / ") thread jack is supplied with the trans-
4
mitter for mounting it on a support or a stand. This
thread jack can be attached to the transmitter housing
by means of commercial plastic adhesive.
4.3 Channel selection
The wireless transmission is made in the 2.4 GHz
range which has been divided by the manufacturer
into five channels with a distance of 14 MHz. As a
maximum, three channels can be used simulta-
neously (channels 1, 3, and 5) as two adjacent chan-
nels will interfere with each other. The following chan-
nel selection is recommended:
for two cameras: channels 1 and 5
for three cameras: channels 1, 3, and 5
Adjust the desired transmission channel with the DIP
switches on the rear side of the housing. The required
position of the switches can be found in fig. 2 and on
the lower side of the transmitter. Adjust the receiver to
the same channel.
4.4 Connections
1) Feed the video signal of the camera or the signal
source via a 75 Ω coaxial cable to the phono jack
"video" (2). 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" and, in case of
stereo transmission, additionally to the jack "audio
B" (3). The input sensitivity is 500 mV.
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.
video recorder for automatic start of a recording).
On the transmitter, the control channel is activated
by short-circuiting the input "switch" (4). Connect
e. g. a motion detector with NO (normally open)
contact to this jack.
