5. Enter the curve direction, parameter A, offset, and follow-up
distance.
6. Press [OK] in the screen shown in step 5 to calculate the
center peg coordinates. The coordinates and azimuth are
then displayed in this screen.
7. Press {ESC} three times to finish spiral calculation and
return to <Road>.
• Press [WIDTH] to move to the width peg setting screen.

• Parameter A input range: 0.000 to 9999.999 (m)
• Station offset /Stationing chainage input range:0.000 to 99999.999 (m)
PROCEDURE Calculation using arbitrary point between KA1 and KE1 as reference
1. In the second page of the OBS mode screen, press
[MENU], then select "Road".
2. Select "Spiral" to enter the spiral menu then select "KA-KE
2".
3. Input the coordinates of the P point (reference point). Press
[OK] to set the input values.
4. Input the coordinates of the arbitrary point on the line
tangential to the P point, then press [OK].
• The azimuth angle to the P point can be set by pressing
