RC Power light Yellow, no go

[telecam]

I updated firmware on both, DJ6 remote controller and Phantom 2 to latest versions. Controller is properly linked (steady green light on Phantom 2), but I can’t start the Phantom motors. Remote controller show a steady yellow power light, not red as it used to be. Any idea what the problem is?

Thanks.

I did a sticks calibration with the RC software and now, all is good. I can power the motors and power light on RC is red.
