idiot in california unable to open battery compartment.

that’s me. i’m the idiot. what must one do to install the battery? i’d rather do it without destroying the device.

Not so idiot the cover is hard to open
On my Quad, it was really difficult to open the cover the first time.

With the back facing you the text at right, the cover slides to the left.

hey, thanks. idiot in california now has his quad charging. when he saw the lip on the back cover he kept wanting it to slide off towards the buttons.

Have you written any of those Yellow book guides? Just kidding, that sliding cover fools many of us. In fact I found it by accident when I slide it off by mistake.
