To extend or retract an individual O/R jack, perform the
following procedure:
1. Using the Jog Dial, or the Arrow Buttons at the
Navigation Control Pad, select the O/R Jack icon
(6, Figure 4-98) (icon will turn orange when selected).
2. Press the Jog Dial, or the OK Button at the ODM, to
make the O/R Jack icon active (icon will turn green when
active).
3. To extend the O/R jacks, position the Outrigger
Extend/Retract Switch (17, Figure 3-9) on the left
armrest to the extend position, then press and hold one
or more of the four buttons at the Jog Dial or Navigation
Control Pad.
To retract the O/R jacks, position the Outrigger
Extend/Retract Switch to the retract position, then press
and one or more of the four buttons at the Jog Dial or
Navigation Control Pad.
NOTE: The O/R jack positions correspond to the four
buttons at the Jog Dial and the ODM Navigation
Control Pad (Figure 4-97 and Figure 4-98).
When a button at the Jog Dial or Navigation Control Pad is
pressed and held, the corresponding O/R jack image turns
orange to indicate that it is actively moving. An arrow will
appear to indicate whether the jack is extending or retracting.
In the following example (Figure 4-98), the top image shows
