Operation
Using the Controls
Sonic Boom switch—this switch has 3 settings:
Automatic, Off, and Manual (Figure 22), as
follows:
• Automatic—enables the automatic movement
of the booms. When in automatic mode the
booms adjust so that the tips of the booms
remain the same distance from the ground.
You can temporarily override the automatic
operation of the booms using the boom
switches to raise or lower one or both booms.
If you raise a boom it will remain raised until
you lower it halfway with the boom switch; at
which point the automatic operation of the
boom continues. If you adjust only one boom,
the other continues to function automatically.
