should be changed soon.

7. Using the Product

This base was specially designed for more extensive adaptability of

the laser. Both the laser and the base can be connected with a

standard tripod by 5/8"-11 thread and camera tripod by

1/4" – 20 thread. With the use of its base, the laser can be freely

rotated, elevated 2-1/2", hung on the wall, attached to a metal plate,

or connected on pipe with use of its strap.

1. As shown in fig. 1, take out the magnetic base.

2. As shown in fig. 2, install the laser on the base (1/4" – 20

thread) by rotating the connecting knob counter-clockwise.

8. Self-Check & Fine Calibration

IM ORTANT: It is the responsibility of the user to verify the

calibration of the instrument before each use.

1. Set the laser on a level flat head tripod centered between two

walls (marked 1 & 2) approximately 15 feet apart. (See fig. 1).

2. Point the laser directly at wall 1. Turn the laser on and mark

the intersection of the beams as point A.

3. Turn the laser 180 degrees so that the laser is pointed directly

at wall 2. Turn the laser and mark the intersection of the

beams as point B.

4. Move the laser and the tripod so the laser is positioned

approximately 2 feet away from wall 1 (see fig. 2). Level the

tripod and position the laser on the tripod facing wall 1. Turn the

laser on and mark the intersection of the beams as point C.

5. Turn the laser off and rotate the laser 180 degrees so that it is

facing directly to wall 2.

6. Turn on the laser and mark the

intersection of the beams as point D.

7. Measure the distance between

points A & C.

8. Measure the distance between

points B & D.

9. If the difference between points

A & C and points B & D are less

than 1/16", your laser is within

its tolerance.

Calibration

Re-calibration can be performed as described below.

1. Use a level to mark a horizontal reference line on the wall.

2. Power on the unit to compare the projected horizontal line with

its references. Compensator has to be locked before

making calibration adjustments. If it tilts, remove the side

plastic screw/plug and use an allen wrench to calibrate the

unit through its side calibration hole. Rotate the allen

wrench clockwise when the horizontal line tilts right. Rotate

the allen wrench counter-clockwise when the horizontal line

tilts to the left.

3. If the horizontal line is too low or too high, carefully

disassemble the window frame by removing the outer plastic

screw/plug and the inner metal screw. Use an allen wrench

to calibrate the adjustment screws located between the

glass prisms. Rotate the allen wrench clockwise when the

horizontal line is too low. Rotate the allen wrench counter-

clockwise when the horizontal line is too high. Reassemble

the window frame after completing the calibration.
