Press "SHIFT" then the number of the function you want like 12 would be "SHIFT 1 2"
To get F12, wouldn't it actually be SHIFT 2. From what I understood the manual to mean if you push 1 after SHIFT you'd get F11. But again this is only for the small Cabs. For the ProCabs you have to program them to use OPTION to get the higher functions.
No, at the bottom of the NCE ProCab/PowerCab throttle are four buttons. From left to right they are:
PROG/ESC EXPN 28/128 SHIFT
Beneath them is a while line , and under the first three are F10, F11, and F12. By pressing the SHIFT button in unison with one of the others you get Functions F10, F11, or F12.
Easier still is to change the OPTION button to access Functions F10-F28, by changing the OPTION button value from 94 to 122. See the manual to see how to do it.
