3. Operation Guide
(a) Installation of battery
• Open the battery-box cap and connect the cords inside with the
two polarities of the 9V battery.
Note: Take the battery out if the instrument if not used for a long time.
• Put the 9V battery into the battery box and close the battery-box cap.
(b) Turn on/off
• Press the on/off button. When Power symbol is
displayed, the instrument is ready for coarse
detection.
• When low battery symbol is displayed, change
the battery.
• Press the on/off button again to turn off the
instrument.
c) Using the clamp holder
1. clamp bolt
2. screw
• Position the instrument on the clamp
holder by the screw of the clamp
holder.
• Position the clamp holder on rod by
the clamp bolt of the clamp holder.

14 ©2007 Johnson Level & Tool
(d) Detection
1. Coarse detection
• Aim the receiving window at the
rotating laser instrument. Loosen the
clamp bolt and move the instrument
up and downwards to receive the
laser scanning signals transmitted by
the rotating laser instrument.
• When the instrument displays like Fig.
(A), move the instrument slightly down-
wards as indicated by the arrow. When
it displays like Fig. (B), move it slightly
upwards as indicated by the arrow.
• When Fig. (C) is displayed, the instrument is at the right position.
• Tighten the clamp bolt and mark the position of the object on the rabbet.
This mark will be the horizontal reference of the coarse detection.
2. Fine detection
1. power symbol
2. fine detection symbol
• Press coarse/fine detection button. The
instrument is ready for fine detection.
• Move the instrument slightly up and
downwards like the coarse detection
procedure.
• When the instrument displays like Fig 6, it is at the right position.
• Tighten the clamp bolt and mark the position of the object on the
rabbet. This mark will be the horizontal reference of the fine detection.
Figure 6

e) Sound function
• If the instrument is working in a circumstance that makes it difficult
to use the display function, the sound function can be used instead.
• Press the sound function button. The sound symbol is displayed
which means it is ready for sound function. The instrument then
conducts coarse/fine detection through sound (buzz) signals.
• When the sound signal is ultra-short buzz, move the instrument
slightly upwards.
• When the instrument makes short buzz, move it slightly downwards.
• When the instrument makes intermittent, continuous sound, it is at
the right position.
• If there is no buzz heard, the instrument has not received the laser
scanning signal.
(f) Turn-off timer
• The instrument will automatically turn off if it has not received
laser scanning signal for 10 minutes
(g) Detector Maintenance
• When you are done using the detector, return it to its packing case.
• Keep the instrument, particularly the detecting window, clean. If
unit becomes dusty, use a clean cloth to gently wipe it clean.
• Avoid knocking the unit over or allowing it to fall on the ground.
• Although the instrument is rain resistant, you should avoid
submerging the unit in water or other liquids. If unit comes into
contact with water or other liquids, wipe it dry immediately.
• Do not use unit around fire or expose it to fire in any way.

8. Self-Check and Calibration
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
X-Direction Accuracy Self-Check
1. For clarity, we define the direction of handle as X-direction,
and another direction as Y-direction
2. Place the unit on a platform that is 25’ away from a wall
indoors, with the handle facing the wall head-on. Unlock the
unit and set to low speed.
3. Mark on the wall where the beam hits the wall and mark that as A.
(Note: This test should be done indoors with dim lighting. It’s
critical that the laser mark is easily seen.)
4. Turn the instrument by 180 degrees, mark the beam as point B.
5. Measure the vertical distance between point A and point B. If A &
B are more than 1/16” apart at 25’, the unit is out of calibration.

B
25’
25’

6. As shown, turn the instrument by 90° and place it on the
platform, with the operating panel facing you. Perform
Y-direction self-check with the same method as X-direction
self-check, and mark point C and point D by turns.
7. If point C and point D are within 1/16” at 25’, the accuracy is
within tolerance. Otherwise reference section 12 of this
document.
Accuracy Calibration
1. As shown in the following figures, screw off the adjustment-hole
bolt with the cross screwdriver, and adjust the fine-adjustment
bolt in the instrument core with a flat head screwdriver until the
laser line in within 1/8” at 50’.
2. Check the accuracy of X-direction with the same method as that
of Y-direction. If the accuracy is
beyond tolerance, make the
calibration of X-direction through the
adjustment hole with the same
method as above.
3. After calibration, rotate the
instrument by 90 degrees in turn to
make sure that the lines on the
wall should be within 1/8” at 50’.
4. Reinstall the adjustment-hole bolt.

18 ©2007 Johnson Level & Tool
Accuracy Self-Check for Vertical Output Status
1. Follow the operations as above, and measure the distance H1
between the laser rotating plane and the platform surface.
2. Set the locking knob to locking position, and place the instrument
horizontally.
3. Adjust the adjusting screw to center the bubble.
4. Measure the distance H2 between the top laser beam and the
platform surface.
5. Mark out E in the position that is (H1 –H2 ) lower than point 0.
6. If e – point 0 < 0.394" (10mm), the accuracy is within tolerance.
Otherwise reference section 12 of this document.
Vertical Bubble Calibration
1. Follow the operations as above, and use a screwdriver to screw
out the bubble-adjustment-hole bolt.
2. Insert the Allen wrench into the adjustment hole to press against
the Allen screw.
3. Rotate the Allen wrench to center the bubble.

4. After adjustment operation, please install the bubble-adjustment-
hole bolt back to its original position.
Note: If you fail to calibrate the accuracy according to the above
steps, please contact Johnson Level & Tool for service.
