When doing the Battery firmware update to 2.0.0.0 to 2.6.0.0 it warns you to turn the camera off. I cannot find any instructions to do that. What does it mean?
1. disconnect the ribbon cables between the chasis and the gimbal?
2. Disconnect phone app and turn wifi off?

I am not prepared to proceed until sure.

On further investigation each battery has to be updated. It is not a 3.08 firmware issue. One battery has already been updated. This must have happened when I had the camera disconnected. So I am going with option 1.
On reflection my firmware 3.08 seemed to do two upgrades. Maybe the second one was the battery firmware. Before removing camera and destroying my retainer clips. I will reapply the firmware with the v2.0 batteries.
