[BC] Denon DN-C680 error codes

[engineermike]

Hey folks,
   Does anyone out there know what an error 201 is on the Denon DN-C680.  It has 
come up on us twice lately on two different machines and the machine has to be 
restarted to get it functioning again.  This last time he was trying to program 
some cuts to play into it.  I'm not sure what he was trying to do the prior time.
Thought or ideas are greatly appreciated.  The manual doesn't list anything that 
we can find regarding this error.
Thanks in advance
Mike
