1.62. Can the Backlights on the Console Keys be turned off?
Question: Can the Backlights on the Console Keys be turned off?

Answer:
Yes, they can. To do so:

1. Simultaneously press the 4 and ? keys for 1 second to enter the console address mode. The console should beep 5 times.
2. Scroll down to the option “Key Backlight.â€
3. Press 0 or 2 to turn the key backlight off completely or turn it on only when a key is pressed, at which point the keys remain lit for about 2 minutes.
4. Press # to confirm the change.
5. Simultaneously press the 4 and ? keys for 1 second to exit the console address mode. The console will read “No Controller Data†and beep for about 5 seconds, then return to the standard top-level display.

What or where is the question mark button? I have an HAI Omni II with four standard blue backlit consoles. I want to disable the backlights until I press a button but I am unable to find a question mark button. Is this an error or is this document for an older console?

I don't remember all the steps off the top of my head but I do remember the two buttons to push are 4 & 6. after that I think it was fairly straightforward.
