SPECIFIC SAFETY RULES FOR THE LASER DISTANCE MEASURE
WARNING: Do not let comfort or familiarity with the product replace strict adherence to product safety
rules. Failure to follow the safety instructions may result in serious personal injury.
WARNING: Do not direct the laser beam at persons or animals. Do not stare into the direct or reflected
laser beam, not even from a distance. Looking into the laser beam or directing the laser beam into someone’s
eyes can cause eye damage, blindness, and cause accidents.
WARNING: LASER RADIATION. Class 2 laser. DO NOT STARE INTO THE BEAM.
1. Device purpose. This Laser Distance Measure is designed to measure distances, lengths, heights, clearances,
areas and volumes. The measuring tool can be used both indoors and outdoors. Using the device for any other
purpose for which it is not designed may result in serious injuries, dangerous radiation exposure, device damage,
and voiding of the warranty.
2. Never shine the laser in your eyes or the eyes of other people or animals. This can cause permanent damage
to eyes. Do not look directly into the laser beam with unprotected eyes. Never look into the path of the beam.
3. If laser radiation strikes your eye, you must deliberately close your eyes and immediately turn your head
away from the beam.
4. Never point the laser beam towards reflecting surfaces. Never point the laser towards people or animals. Even
a laser beam with a low output can cause damage to the eyes.
5. Do not allow children to use the laser measuring tool. They could unintentionally blind other persons or them-
selves.
6. Device inspection. Before operation, check the device and batteries for any damage or missing parts. Do not use
the device if any part is missing or damaged. Make sure all adjustments are correct and all connections are tight.
7. Do not try to open or disassemble your measuring device. Never open the laser module as unexpected exposure
to the beam can occur. The laser cannot be replaced with a different type of laser.
8. Cleaning. Never use solvents to clean plastic parts. Solvents could dissolve or otherwise damage the material.
Use only a soft damp cloth to clean plastic parts.
9. Do not make any modifications to the laser equipment. Have the measuring device repaired only by qualified
specialists.
Safety is a combination of common sense, staying alert and knowing how your item works.
SAVE THESE SAFETY INSTRUCTIONS.
WARNING: Read and understand all warnings, cautions and operating instructions before using this
device. Failure to follow all instructions listed below may result in personal injury and device damage.

chargeable batteries (not included).
NOTE: More measurements are possible when using 1.5V rechargeable
batteries rather than 1.2V rechargeable batteries.
1. Push the tab (Fig. 1 - 1) inwards and pull upwards to remove the bat-
tery cover (Fig. 1 - 2).
2. Insert two AAA batteries (not included) into the battery compartment
(Fig. 1 - 3). Follow the diagram inside of the battery compartment to
place the batteries in the correct orientation.
3. Replace the battery cover (Fig. 1 - 2) and press into place.

OPERATION
UNIT SELECTION
You can use your device to measure in four different units. The available units are: meters (m), feet (ft), inches
(in), and feet/inches (' ").
NOTE: The feet or inches units will give you measurements in decimals, whereas the feet/inches unit will give you
measurements in a combination of whole feet and whole inches.
To switch between units: While holding the mode button , press the measurement button until your de-
sired unit is displayed on the screen.
CHANGING MODES
After powering your measuring device ON, the default mode is distance measurement . To switch to a different
mode (distance /area /volume ) press the mode button . In the following sections, you can find more
information about how to use each mode.
WARNING: Do not direct the laser beam at persons or animals. Do not stare into the direct or reflected
laser beam, not even from a distance. Looking into the laser beam or directing the laser beam into someone’s
eyes can cause eye damage, blindness, and cause accidents.
SELECTING THE MEASURING REFERENCE POINT
You can set your measuring device to measure from either the base of the unit or from the top of the unit. See
Figures 2 and 3 below to learn more about the two reference point options.
To change the reference point: While holding the mode button , press the power button to switch between
reference points.
Fig. 2 Fig. 3
From the Base From the Top
NOTE:The measurement value appears after a few seconds. The measurement will take longer to appear
depending on the distance, light conditions, and reflective properties of the target surface. The end of the mea-
surement is indicated by a tone. The laser beam automatically shuts off after the measurement is completed.

MEASURING A DISTANCE
The distance measuring function is for measuring distances, lengths, heights, and clearances. This
function is depicted by the arrow symbol .
OPERATION
WARNING: Do not direct the laser beam at persons or animals. Do not stare into the direct or reflected
laser beam, not even from a distance. Looking into the laser beam or directing the laser beam into someone’s
eyes can cause eye damage, blindness, and cause accidents.

row symbol . If you’re in a different mode, press the mode button
until you see the arrow symbol on the screen.
2. Make sure to set your measuring device’s reference point and units
(see p. 8).
3. If the laser beam is not ON, press the measurement button to
activate the laser. You will see the laser icon in the top left corner
when the laser is activated. Aim the laser at the point of measurement.
4. Press the measurement button again to take the measurement.
The value will be seen on your display. Your screen will look like Fig. 4.
MEASURING AN AREA
The area measuring function is made for calculating the area of a rect-
angular space. This function is depicted by the area symbol .
1. Make sure you are in area measuring mode depicted by the area
symbol . If you’re in a different mode, press the mode button un-
til you see the area symbol on the screen.
2. Make sure to set your measuring device’s reference point and units
(see p. 8).
3. If the laser beam is not ON, press the measurement button to
activate the laser. You will see the laser icon in the top left corner
when the laser is activated. Aim the laser to measure the length. Press
the measurement button again to take the measurement. The
value will be seen on your display.
4. Repeat step 3 to measure the width. The area will automatically cal-
culate after the second measurement is taken. The value of the width
measurement will be seen on the top row of your screen and the area
will be on the bottom. Your screen will look like Fig. 5.
NOTE: A line will appear on the edge of the area symbol to indi-
cate which measurement you are recording.
Fig. 4
NOTE: The laser will automatically
shut off after 30 seconds of inactiv-
ity to prolong battery life and limit
accidents.
NOTE: The bottom number on your
display is the current measurement
being recorded. If you take multiple
measurements, the previous mea-
surement moves to the top row.

you will hear a tone. Press the measurement button to exit continuous measuring mode.
NOTE: The device will not save the measurements while you are in continuous measuring mode. The laser stays
on the duration of the continuous measurement. DO NOT shine the laser towards people or animals.
MEASURING VOLUME
The volume measuring function is made for measuring the volume of a rectangular prismatic space. This function
is depicted by the cube symbol .
OPERATION
WARNING: Do not direct the laser beam at persons or animals. Do not stare into the direct or reflected
laser beam, not even from a distance. Looking into the laser beam or directing the laser beam into someone’s
