Argh! I forgot you are blind!

Right... Let me try that again.

I cannot speak for the FM, but with the JBR, the disk does not spin up for
about 9 seconds, but be assured that tapping the ON button DID work. In
fact just testing now, I notice that the screen does not even switch on for
about 4 seconds, but (fwiw) the two little LEDs at the top of the unit
light up immediately.

When the mains is connected, you need to keep holding the ON button until
you hear/feel the disk spin up or you see the third little blob on the
screen. Tapping ON when mains is connected will put the unit into charge.

Hopefully that's more helpful.
