Use the Y axis points and the Z axis points box to specify which way the RT’s axes 
point in the vehicle. Figure 6 on page 38 shows the RT axes directions. The Orientation 
page of the configuration wizard, shown in Figure 19, also has illustrations to visualise 
the orientation of the RT in a vehicle based on the settings input. The advanced settings 
will change to show the three rotations associated with orientation input  even when 
unavailable.

For correct initialisation, it is necessary to get the heading orientation correct. The RT 
gets its initial heading by assuming the vehicle is travelling forwards in a straight line. If 
the definition of the vehicle’s x-axis (forward direction) is incorrect in the RT then it will 
not initialise correctly when the vehicle drives forwards. 
If the vehicle level option (see Vehicle starts, page 67) is used, then the pitch and roll 
orientations must also be correct. 
To make small adjustments, select the Edit advanced settings checkbox to enable the 
rotations for editing. This allows any slip angle, pitch or roll offsets to be zeroed.
