I'm on my netbook and all my back Treo archive is on my big laptop which
I left at work, so I probably have the wrong subject and I know I forget
who actually gave me the answer (was it George?) - anyway, after being
out of range or turning off a BT headset, what seems to work is tap the
answer button as though to answer a call.
It's worked with my Supertooth and so far one of the Plantronics. So
thanks to whoever gave me the suggestion. Not quite what I was hoping
for, but lots easier than going through the radio menu.
