My mistake.  I was operating from memory.

To do a factory reset:

Power Off

Hold down [7] [8] [9] and power on.  This will bring up a menu of 
various reset types.


To go in Dianostics mode and find out the ROM Revision:

Power Off

Hold down [0] [-] [+] and power on.  This will bring up the ROM 
Revision and put you into diagnostic mode to test all of the 
functions, knobs, keys, etc, etc.  You can just power off at any time 
when in this mode without any effect.
