[Checks]
Position a target Point A at a distance 30m - 50m away from the instrument,and sight
it with the telescope.
Loosen the telescope lock screw and turn the telescope until a point is sighted at a
distance roughly equal to that of Point A. This is Point B.
With the telescope still reversed loosen the horizontal lock screw and rotate the
instrument around the vertical axis, and sight Point A again.
Loosen the telescope lock screw and turn the telescope until a point is sighted at a
distance equal to that of Point B.This is Point C.
No adjustment is necessary if Point B and C are aligned.
[Adjustments]
If Points B and C are not aligned, mark Point D at 1/4 the length of the BC,from Point C
in the direction of Point B.
Using the adjustment pin, rotate the reticle adjustment screws horizontally opposite
each other (see preceding page), and move the reticle to sight Point D.
Repeat the check and make sure the adjustment is correct.
❈ Since the R-322NX, R-322EX,R-323NX and R-323EX have triple axis compensation,
it is necessary to make other settings besides the adjustments mentioned above.
For details, contact the dealers from whom the instrument was purchased.
