This is a copy of the email I received when I asked the factory the same question.

"Hello,



can you have a look to the software version of your Cockpit? Newer Versions show the Version when you turn on the PowerBox on the right side of the Logo.



Older Version:

Turn on the PowerBox. Disconnect the batteries. Hold Button I&II and connect one battery. If you have a version 03 or higher you will have no problem with the sequencer. This issue is solved since May 2011- some days after bringing the PowerBox Cockpit to the market. The guy in the forum seems to have very old versions- one of the first. I´m wondering because we informed our customers…



The thing with the Power off the receiver was a customers fault. He connected his Futaba receivers wrong. Newer Powerboxes have fuses inside, so also mistakes done by customer will not short the Powerbox out."
