The RC 5808  is a simple 12v, 8 channel video receiver with a  single Video output for a monitor or goggles.  I’ve had mine for over a year and I’m completely happy with it.

The following channels and its frequencies are supported:

CH1 5.705 GHz
CH2 5.685 GHz
CH3 5.665 GHz
CH4 5.645 GHz
CH5 5.885 GHz
CH6 5.905 GHz
CH7 5.925 GHz
CH8 5.945 GHz

In order to change the frequencies, change the pin positions found on top of the receiver:

The pin combination assignment to change the channel is found at the back of the receiver:

To change the channels, position the pin to closed or blacked out half.  For example, figure 1 above, is set to use channel 8 (with reference to figure 2).
