alarm  and  one  of  the  LEDs  will  flash.  LED  will  show  the  direction  for  the 

receiver for beam detection. Move the receiver until you will hear contini-

ous sound alarm and middle signal LED will flash. With the help of bubble 

level check the leveling of the receiver housing. Mark the surface. Place the 

detector on the staff with the help of clamp. 

TO CHECK THE ACCURACY OF LINE LASER

Set up the instrument between two walls, the distance is 5 m.Turn on the 
Line Laser and mark the point of cross laser line on the wall.Set up the in-
strument 0,5-0,7m away from the wall and make, as described above, the 

same masrks. If the difference {a1-b2} and {b1-b2} is less then the value of 
“accuracy” (see spesifications), there is no need in calibration.
Example:  when  you  check  the  accuracy  of  Line  Laser  the  difference 
is  {a1-a2}=5  mm  and  {b1-b2}=7  mm.  The  instrument’s  error:  {b1-b2}-
{a1-a2}=7-5=2 mm. Now you can compare this error with standard error. If 
the accuracy of Cross Line Laser isn’t corresponding with  claimed accura

cy, contact the authorized service center.

TO CHECK THE ACCURACY OF HORIZONTAL BEAM

Choose a wall and set laser 5M away from the wall. Turn on the laser and 
cross laser line is marked A on the wall.Find another point M on the hori-
zontal line, the distance is around 2.5m. Swivel the laser, and another cross 
point of cross laser line is marked B. Please note the distance of B to A 
should be 5m. Measure the distance between M to cross laser lune, if the 

difference is over 3mm, the laser is out of calibration, please contact with 

seller to calibrate the laser.

TO CHECK PLUMB

Choose a wall and set laser 5m away from the wall. Mark point A on the 
wall, please note the distance from point A to ground should be 3m. Hang 

a plumb line from A point to ground and find a plumb point B on ground.
