2. Features and Functions
• Large electronic self-level range: The unit works when within
±5°. When beyond the ±5° leveling range, the laser line flashes,
rotation of the beam stops, and an audible alarm activates.
• Vertical and horizontal working modes: electronic self-leveling in
both horizontal and vertical mode with one rotating laser beam
and one 90º split beam.
• Two rotational speeds: 200 and 500 rpm
• Scan function adjusts the scan line size and scan direction.
• Out-of-level alarm ensures the working accuracy.
• Fine self-calibration function
• In “Tilt Mode” the laser will stop rotating and flash when bumped
to ensure work accuracy.
• Slope function allows the user to perform slope in both
X & Y axis.
When the power indicator light is flashing on the charger, the battery
is low and the life of the battery can be extended when charging
the battery in its lowest voltage. Charge the rechargeable battery
every two or three months if the laser will be unused for a long
period of time.
Before Using Your Laser Level
When you charge the new battery or one which has not been used
for long periods of time, it may not reach full charge until after
you have discharged it fully in use and recharge it several times.

IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
The instrument must be self-checked before operation. If the
accuracy is found beyond tolerance, user can make adjustment
according to directions as follows.
X & Y-Direction Accuracy Self-Check
1. Note the X & Y-direction on top of the laser.
2. Place the unit on a platform or tripod that is 50’ away from a
wall indoors, with the X-direction facing the wall head-on. Turn
the unit on.
3. Using the detector mark on the wall where the beam hits the wall
and mark that as A.
4. Turn the instrument by 180 degrees and mark the beam as point B.
5. Measure the vertical distance between point A and point B. If A &
B are more than 1/32” apart at 50’, the unit is out of calibration.
6. Turn the instrument by 90° and place it on the platform, with
the Y-direction facing the wall. 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 1/32” at 50’, the accuracy is
within tolerance.
Fine Calibration Using the Remote Control
The following procedure is only valid when adjusting out errors that
are less than 1/2” over 100ft. Errors larger than 1/2” at 100ft. must
be done by a qualified technician. Reference section 12 for further
information.
1. Access calibration mode by simultaneously pressing the Power
button and the TILT button .
2. While continuing to hold the TILT button, release the
Power button until the X & Y LED’s blink 3 times then release
the tilt button.
3. Release the TILT button.
• Note that the rotating head of the laser is rotating, and the
X-axis LED is flashing. The unit is now in calibration mode
and all other operations will be performed with the unit’s
remote control.
4. Open the lower cover of the remote
control to access the operation panel for
the calibration.
• Multiple presses of the X/Y button
toggles calibration control between the X-axis, Y-axis and
