That works very well for the FM/V2, but the hardware timeout on the
older models may be very short, less than a second on my recorder.

That's exactly how it works for the FM/V2 in the original firmware, but
I don't think it'll work on the older models, since the user isn't
likely to let go of the OFF button that fast. ANd as I said above, my
recorder shuts off in about 1 second.

We should still implement it on the FM/V2 platforms, though.

Perhaps. I don't think it's *that* important, as long as the shutdown
sequence is long enough to allow the user to release the button in time.
