Marking A and B Locations
The Straight-line and Curve AB guidance modes require a reference guideline to guide the vehicle
along. Establishing a guideline involves marking two points along the reference guideline. To
establish this reference guideline using the real-time menu, use Up or Down to scroll in the menu
until <NEW AB?> is displayed on the lightbar (See Figure 33), and press Enter. The menu item
<MARK A> is displayed. Mark the A location by pressing Enter when the desired location is
passed. The menu item <MARK B> is now displayed. To mark the B location, press Enter when
the desired location is passed. The reference guideline is now established and the lightbar dis-
plays guidance information. See the underlined caution under “Curve AB Guidance Operation” on
page 45, when establishing AB guideline for Curve AB operation.
Switching between Guidance Modes
There may be situations where it is necessary to switch between guidance modes. Typically an
operator makes one or more passes around the field’s headland area in the Headland guidance
mode. While driving the headlands, the operator may mark the A and B guideline points to be used
when switching modes. When the headlands are completed, the operator switches to the Straight-
line or Curve AB mode, and completes the field in a back and forth fashion.
To switch between guidance modes, scroll the real-time menu (See Figure 32 on page 32) until <HEAD-
LAND>, <STRAIGHT>, or <CURVE AB> appears in the text window. When the desired mode is displayed,
press Enter to make it active.
