Answered: Flashing amber light ?

I’ve tried a different transmitter and a different reciever , but still only the battery lights up green , no Rx1 light and the amber light flashes constantly .
No motor or servo response .

Any idea whats wrong ?

Meccano Man,

A fast flash on the amber LED indicates the PIC is performing an autonomous routine.
Please re-download user code or default code.

A list on the meaning of the different LEDs on the PIC can be found here: https://vexforum.com/wiki/index.php/VEX_Microcontroller_V0.5
