Radio: Devo 10
Firmware: Deviation 2.1.1
Problem: Radio restart at complex mixer page.
How to reproduce:
At the throttle channel (I didn't try at other channels)
1. Already has 1 complex mixer setup
2. Try to set up a 2nd complex mixer
3. Increase <Mixers> from 1 to 2
4. Increase <Pages> from 1 to 2
5. Press R key at <Switch>
6. Radio reboot by itself
Hope this helps.
