Laser Safety
• Use the tool only with the specifically designated batteries.
• Store the tool out of reach of children and other
untrained persons. Laser tools are dangerous in
the hands of untrained users.
• Tool service must be performed only by qualified repair
personnel. Repairs, service or maintenance performed
by unqualified personnel will void the warranty. Only
approved and authorised service technicians can carry
out warranty repairs.
• Do not use optical tools such as a telescope or transit
to view the laser beam. Serious eye injury could result.
• Do not place the tool in a position which may cause
anyone to intentionally or unintentionally stare into
the laser beam. Serious eye injury could result.
• Do not position the tool near a reflective surface
which may reflect the laser beam toward anyone’s eyes.
Serious eye injury could result.
• Do not use the tool at a position where the
laser beam can cross any person at head height.
• Do not let children come in contact with the tool.
• Turn the tool off when it is not in use. Leaving the tool
on increases the risk of staring into the laser beam.
• Do not operate the tool around children or allow
children to operate the tool. Serious eye injury may result.
• Do not remove or deface warning labels.
Read the following safety instructions before attempting to operate
this product. Keep these instructions in a safe place for future reference.

MEASUREMENT
Single measurement (Fig.3)
• Press the read button. The laser will be emitted.
• Re-press the read button for a single distance measurement.
Results will be displayed on the main measurement display.
• The previous three measurements will also be displayed above
the main measurement display.
Continuous measurement (Fig.4)
• Press and hold the read button. Minimum and maximum
results will be displayed on the display screen.
• Press the read button or off / clear button to exit continuous measurement.
Area measurement (Fig.5)
• Press the area / volume / pythagoras button.
A rectangle will appear on the display screen.
• Press the read button to measure the first edge (width).
• Press the read button to measure the second edge (length).
• Area will be calculated automatically with results shown on
the display screen.

Pythagoras measurement
• To calculate the unilateral distance of a triangle pythagorean mode
can be used. When taking measurements of the triangle, ensure the
length of the right side is shorter than the length of the hypotenuse.
If not, the instrument will display an error signal.
• To ensure the accuracy of measurement, take measurements from
the same starting point of the first order hypotenuse. Then follow
with the measurement of the right side. Please follow the instructions
according to the method required. (See Figs.5-8 to determine the
appropriate method).
1. Calculate the side of a right angle triangle (Fig.7)
Press the area / volume / pythagoras button three times to enter
pythagorean mode. Follow the instructions displayed on the screen as follows:
• Press the read button to measure the length (a) of the hypotenuse.
• Press the read button to measure the length (b) of the rectangular side.
• Length (x) will be calculated automatically with results shown on the
display screen.
