Safety Instructions for Digital Laser Level
WARNING
LASER RADIATION. Do not stare into
beam. ClassII laser product. Turn the
laser beam on only when using this
tool.
• Do not remove or deface any
product labels.
• Avoid direct eye exposure. The laser
beam can cause ash blindness.
• Do not operate the tool around chil-
dren or allow children to operate the
tool.
• Do not place the tool in a position that
may cause anyone to stare at the laser beam, whether intentionally or unintentionally.
• Do not use on surfaces,such as sheet steel, that have shiny, reective surfaces. The shiny
surface could reect the beam back at the operator.
• Always turn the laser tool off when not in use. Leaving the tool on increases the risk of
someone inadvertently staring into the laser beam.
• Do not attempt to modify the performance of this laser device in any way. This may result in
a dangerous exposure to laser radiation.
• Do not attempt to repair or disassemble the digital laser level. If unqualied persons attempt
to repair this product, serious injury may occur. Any repair required on this laser product
should be performed only by qualied service personnel.
• Use of other accessories that have been designed for use with other laser tools could result in
serious injury.
• Do not place or store tool under extreme temperature conditions.

particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures: Reorient or relocate the receiving antenna. Increase the separation between the
equipment and receiver. Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected. Consult the dealer or an experienced radio/TV
technician for help.
DANGER
People with electronic devices, such as pacemakers, should consult their physician(s)
before using this product. Operation of electrical equipment in close proximity to a heart
pacemaker could cause interference or failure of the pacemaker.

OPERATION
1. BATTERY INSTALLATION
This multi-function digital laser level uses
two “AAA” alkaline batteries to power
both the LCD module display and the
laser dot.
a. Open the battery cover, located in
the middle of the back of the level.
b. Insert two new “AAA” alkaline
batteries with the polarity (+/-)
as indicated on the inside of the
battery compartment.
c. Replace the cover and close it
securely.
NOTE:
• Always turn off the tool before installing or replacing the batteries.
• Remove the batteries from the tool when not using it for extended periods.
• The 2 AAA batteries should match each other in brand and type.
• Do not mix old and new batteries.
• Remove depleted batteries immediately, and dispose of them according to the laws and
regulations governing your community.
2. TO TURN THE DIGITAL LASER LEVEL
ON AND OFF
a. Press the power button to turn
the digital laser level on. When
the screen rst comes on, the
temperature is displayed in
Fahrenheit for about 2 seconds,
to indicate whether level is being
used in the optimum operating
temperature range.
b. The current angle of the digital
level is then displayed, and a slope
line of that angle is shown either
above or below the line for true level. An arrow on the display indicates whether the
digital laser level has to be moved up or down to be level. True level is reached when
the two lines are together and the angle shows 0.00°.
c. To turn off the digital laser level, press and hold the button for about 2 seconds.

OPERATION
NOTE:
• If not used for 5 minutes the digital laser level automatically turns off.
• The LCD display is large and easy to read. When the digital laser level is turned upside
down, the LCD screen senses this and changes to read correctly in the inverted position.
3. CALIBRATE THE DIGITAL LASER LEVEL
NOTE: The digital laser level has been pre-calibrated to operate in high-accuracy-display
mode. The high accuracy display (the digital reading displays two decimal places) is only
available when the unit is set to degree or % and the gradient is within 1º. If the gradient
exceeds 1º, the LCD display will revert to regular accuracy display (the digital reading
displays one decimal place). Signicant temperature changes can cause the digital laser
level to revert to regular accuracy display. We suggest calibrating the digital laser level
every time before you use it.
To ensure an accurate measurement, the calibration should be performed separately for
horizontal measurement and plumb (vertical) measurement.
a. Place the digital laser level on a at and smooth surface. Press and hold the REF
button for about 3 seconds. The calibration mode is activated. “CAL1” will blink on
the LCD display.
b. Keep the level motionless for a few seconds, until the beeper sounds for 1 second,
then “CAL2” will show on the LCD screen.
c. Rotate the digital level 180º in the same location. Press the REF button. “CAL2” will
blink on the LCD display.
d. Keep the level motionless for a few seconds, until the beeper sounds for 2 seconds
to indicate that calibration is complete. The LCD display will show the current angle
in the LCD display.

OPERATION
NOTE:
• Calibration must be performed on a at and smooth surface with the gradient no more
than 5º. If it exceeds 5º, the beeper will sound for 3 seconds, and “Err” will show on the
LCD display to indicate that the calibration failed, and calibration will stop automatically.
• If, during calibration, the digital laser level is moved, “Err” will show on the LCD screen,
with no sound.
• After CAL2 shows on the LCD, the digital laser level should be rotated 180° to start
CAL2. If the digital laser level is not moved prior to starting CAL2, the digital display will
incorrectly identify the current working surface as 0°. Re-calibrate the digital laser level,
and it will recover to normal function.
4. ABSOLUTE ANGLE MEASUREMENT
Unlike common levels, this digital laser
level allows you to make 360° angle
measurements with superior accuracy.
a. Press the power button to turn
on the digital laser level. Lay the
digital laser level on a working
surface with the base at against
the surface. The display indicates
the absolute angle between the
working surface and true level.
The zero line indicates the true
level position, and the slope line
indicates the direction of the
working surface either above or below true level.
b. To level the working surface, move the surface with the level on it until the two lines
on the readout match and the readout is 0.00° for the angle.
c. To plumb the working surface, move the surface with the level on it until the two
lines on the readout match and the readout is 90.00° for the angle.
d. Using the bubble vials you can also level or plumb the working surface when the
bubbles are exactly in between the marks on the vial.
NOTE: If the beeper is activated, the digital level will sound at 0°, 45°, 90° or the most
recently stored value.
