Rotary knobs and arrow keys
The USM 36 is equipped with two rotary knobs.
Use the left-hand rotary knob to directly set the gain; the
right-hand rotary knob is meant for setting the currently
selected function.
You can use the two rotary knobs to make both incre-
mental and accelerated settings. You can achieve an in-
cremental setting by turning the rotary knob slightly until
it locks into the next setting. Use the rotary knob contin-
uously at a constant speed to achieve an accelerated
setting. In this way, you can change the values quickly.
As an alternative, you can use the arrow keys below the
display screen for changing the settings. If you keep the
arrow key pressed down, the value changes faster.
