2. Select "IP&Tan" to enter the intersection angle/azimuth
angle calculation menu.
3. Input the coordinates of the BP point (reference point).
Press [OK] to set the input values.
4. Input the coordinates of the IP point, then press [OK].
• The azimuth angle can be set by pressing [AZMTH] on the
second page.
5. Input curve properties: direction (of curve), IA (intersection
angle), BP-IP (distance between BP Point and IP Point), IP-
EP (distance between IP Point and EP Point), Para A1
(parameter A1), Para A2 (parameter A2), radius (of curve),
and St. ofs (BP Point offset).
6. Press [OK] in the screen shown in step 5 to calculate the
coordinates and follow-up distance of the KA1 point, KE1
point, KE2 point, and KA2 point. The results are then
displayed on the screens shown here. Press {}/{} to
switch between <IA&Tangent/KA1>/<IA&Tangent/KE1>/
<IA&Tangent/KE2>/<IA&Tangent/KA2>.
