route widths (route width from the center peg to the LEFT width peg). When both route widths are input
as positive (+) "R" and "R2" are used. When both route widths are input as negative (-) "L" and "L2" are
used.
• A blank space at the beginning and end of a point name will be ignored.
• If the length of the point name being input exceeds 16 characters, 1 character at the beginning will be
deleted for each new character input at the end of the point name.
25.8.6 Arbitrary point calculation
The coordinates of arbitrary points on every calculated curve can be found using arbitrary point calculation.
PROCEDURE
1. In the second page of the OBS mode screen, press
[MENU], then select "Road".
2. Select "Alignment" to enter the Route Calculation menu.
3. Select "Calc coord" to enter the arbitrary point calculation
menu.
4. Input the arbitrary point follow-up distance.
5. Press [OK] in the screen shown in step 4 to display the
coordinates and point name of the arbitrary point.
• The center point can be stored as a known point in the
current job by pressing [REC].
6. Press {ESC} to return to <Alignment>.
• Press [OFF] to move to the width peg setting screen.

Rules regarding the automatic assigning of point names to arbitrary points
• Arbitrary point: The distance to the arbitrary point is given in terms of the closest peg No. from the front
of the curve. The distance from the peg No. is added at the end.
• If the length of the point name being input exceeds 16 characters, 1 character at the beginning will be
deleted for each new character input at the end of the point name.
