Set an object (point A) at a distance of 30 to 50m away from the

instrument and sight it through the telescope.

Loosen the telescope clamp screw and reverse the telescope around

the horizontal axis. Mark a point set on the line of sight at about the

same distance to the object point A, and call it point B.

Loosen the horizontal clamp screw, and rotate the instrument around

the vertical axis. Sight point A again.

Loosen the telescope clamp screw, and reverse the telescope around

the horizontal axis. Mark a point on the line of sight at about the same

distance as point B, and call it point C.

No adjustment is necessary if point B and C coincide,

but if it does not - Consult with your dealer.
