Yeah, a few AA cells in line would work. Each one is 1.5 volts, so just
divide the voltage you want (not sure what voltage the FMR uses - my JBR20
uses 9v) by 1.5 to get the number of cells.

couldn't replace the batteries once they had run out. What I want to know is
there any way of using an external battery pack through the charging socket?
I'm no electronicx expert so wouldn't know where to start - I mean, can I
just connect a few AA batteries in line?
