hi bud, if you havnt messed with the settings then it should be at 15bps(10 flashes) anyway, so when you press the function key twice it should go on to a soild green for about 2 secs in that time press the power button 6 times and that should get you down to 12 bps after that you should see 4 flashes to confirm its on 12bps.
just thought id post coz it took me a while to twig on you have to set it when the light is solid green. =P
