Hi Dirk

Do I need to disconnect the battery if I just want to change the SD card to play against the CT800.

Last night I just changed the SD cards and when I rebooted the Centaur, all that
happened was the led board lights just kept revolving.

I tried to just pull the battery connection apart from the circuit board but it wouldn't move and I didn't want to force it in case I broke anything.

Regards
Bryan
