Casio CZ/ VZ/ FZ - Pro Series

Hi, I've just bought a Casio CZ5000, problem is I can't work out how 
to use the record function on the sequencer! I have tried pushing the 
record button and various other things but to no avail. Am I doing 
something wrong or have I got a dud keyboard. Unfortunately It didn't 
come with the manual.

Please could anybody give me a simple step by step guide on how to 
use this feature.

And where I can obtain a manual?

Any help would be much appreciated.
