- Switch 1 on 35MHz (red) and 2G4 (Green)
- Switch 2 switches HoTT (Green) and spectrum (red)
It follows:
- Only Red: 35MHZ (of 2G4 branch remains inactive yes, why the second switch nothing lights up)
- Green / Green: HoTT
- Green / red: spectrum
The channel is automatically switched on or switched off query - depending on the selected module.
PS: Of course, the plug does not fit to the spectrum system, in this case everyone must pick up the piston.
But everything else was taken into account and all the cables - also for cascading - are included.
Conclusion: I am glad that I bought this not very cheap switch -> a round and foolproof thing!
