Hi all, I bought a demo H920/CGO4 from a local store. The AC is brand new (never used before). Charged all batteries and wanted to take it outside but noticed that the LED satus is not blinking. Binding worked out, CGO4 works just fine, have all controls on ST24. Any advice on what could cause the problem ? I've never been able to see a blink from that LED. Wires aren't damaged. Thanks !
