I have a 3PK,have had no troubles with until last week,I have not used it for about two months,turned it on the other day to see how low the battery was and now it will not turn off.The only way to shut it off is to unplug the battery,anyone else have this problem,do I need to ship it back to Futaba or can I fix it,any help would be great,thanks.

Is the display switch on the side turned on?

just what I was thinking....

check it and let us know

Me too - a real common occurence. 3PK has two places that will turn the screen on. Make sure both are off - main power and the switch on the left hand side of the screen.
