Casio CZ/ VZ/ FZ - Pro Series

So... I want to store three banks' worth of my favorite CZ patches as
sysex files.  Umm...why can't I find out how to do this from the
archives?  Is there a bulk dump command that will spurt out the data
for all 16 patches in internal memory, for saving as a sysex file (I
use the fairly rudimentary Alesis Freeloader to load patches into my
synths, including the CZ)?  If somebody can give me step-by-step
instructions on how to accomplish this, I would be really grateful...
