8. Self-Check & Fine Calibration
IMPORTANT: 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.

15. Trouble Shooting
• If the unit does not turn on, check the battery polarity or install new
batteries and clean the battery terminals.
• If the laser does not illuminate, check the battery polarity or install new
alkaline batteries and clean the battery terminals.
• If the unit is out of calibration less than 1/2" at 35', follow calibration
procedure in manual.
• If the unit is out of calibration more than 1/2" at 35', contact an authorized
Johnson service center or Johnson Level & Tool's customer service
department.
• If the unit will not calibrate, contact an authorized Johnson service center or
Johnson Level & Tool's customer service department.
• If the unit beeps and/or flashes constantly, check to see if the unit is being
tilted to angles beyond the self-leveling range. If so, push the "horn" button
to engage manual mode. If the unit is being used for a level application,
place onto a surface that is within the self-leveling range. If it is still beeping
and/or flashing, the unit is out of calibration.
• If the unit turns off after a short time, install new alkaline batteries and
clean the battery terminals. Also, make sure that the on/off knob is in the
on position.
