adjustment
Set doesn’t need special knowledge and expensive tools for installing. The most important is proper
positioning of transmitter and receiver a according to recommendations of instructions and aligned
relative antennas to each other. System in ECO version hasn’t radio measurement function and in-
staller can verify antennas setting only optically. When the antenna isn't set exactly and the weath-
er conditions are unfavourable(snowstorm, fog, heavy rain) may appear deterioration of image
quality and will be necessary correcting antenna settings.
PRO version has radio function of measurement system.
You must set radio channel before you connect power supply. Rotary
switch on the transmitter and receiver is used to this. Adhere to the
following instructions
1. Radio channel must to be set the same in transmitter and receiver.
2. When we are dealing with sets work in immediate vicinity or in close proximity to transmitter
and receiver, channels must be set every second one.
3. Number of radio channel are the same like number on switch.
4. Setting switch to position 0 is equivalent to selecting channel 1
