To tell what your unit is currently set at:

- Switch the unit on (on the bench if you like).
- Press and hold the M button for 15 seconds for service menu.
- Cycle through the service menu until you see DSP.
- DSP = 0 means you have Standard HI-FI system.
- DSP = 1 means you have the Logic 7 seperately amplified system.
