JUMPER T8SG Problem of connexion

Hi everybody !

I have a problem on my new T8SG Jumper (yellow) : It doesn't switch on and a usb pic appears on the screen.
I think I'm supposed to download a file but I don't know which choose.
Can someone help me ?

Thank you

Tom

Go to the User Manual link in the left column for Devo 7e/10/12e (similar to t8sg). Follow the directions in the Installation section to do a fresh install of deviation firmware (available in the Downloads link). That should get the tx going as long as it's not a hardware problem.

Thank you for your help. I read the manual (pdf) and watched the video about setting up.
Now I try to set up aux 4 or 5... if someone have an idea on this topic...
