LOCKOUT MODE:

If neither mode button is depressed for
several minutes, most of the front panel illumi-
nation turns off and the mode buttons become
inactive. This feature serves several purposes.
It saves power, reduces ambient light when
doing video work, and most importantly keeps
prying fingers from messing with your controls!
To gain access to the mode functions again,
depress both mode buttons for several sec-
onds until the front panel illuminates again.
