DJI Compass problem TBS Discovery - engines will not start

[JVDS30]

Hello, I do suffer a frustrating problem with my TBS.

All setting are correct to my knowledge (no gps installed)
Than when powered up, first three greens, after that orange double blink.
Seems to be a compass problem, when switch between ATTI and MAN 6 or more times, nothing happens.
Engines will not start. What could be wrong?

See what it does:

Hè,

This is no compass problem because the compass is in the gps unit,
Have you calibrate your stick movement in the assistent software ?
Make sure all the sliders in the assistent software move the correct way

As mentioned above, no GPS = No Compass.. How are you trying to start your motors? What radio setup do you have? Did you calibrate anything in the assistant?
