button will turn the laser back on to its original setting. This
“sleep” mode can be used to save on the battery life if the laser is
not going to be used for a period of time.
If the laser is not used after sixty minutes in “sleep” mode, the laser
will power off automatically and all stored information will be lost.
The 40-6715 laser detector is an indispensable accessory when
using rotary laser levels. The main function of the detector is to
detect the position of the laser signals that are transmitted by rotary
lasers. This detection quickly and precisely provides the user with the
horizontal reference.
This product features high sensitivity, a double-faced display, low
power consumption, good reliability and easy manipulation. It can be
used with most types of rotating laser levels.

low and needs to be replaced. If the battery is very low,
the unit will power off automatically. Replace the battery.
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
The instrument must
be self-checked for
accuracy periodically,
specifically before a
large project, where
accuracy is critical.
If the accuracy is found to be beyond tolerance, some adjustment
may be made as follows.
X-Axis and Y-Axis Accuracy Check:
1. Place a table indoors, approximately 20m from a wall. Place the
instrument on the table with the X-axis facing the wall.
2. Power the instrument on and allow it to self-level. Adjust the
rotating speed to make the output laser line clear and visible.
Mark a vertical line on the wall that intersects the laser line from
the instrument. Mark a line where the laser line hits the vertical
line, and label as ‘A’.
3. Rotate the instrument 90°, and after self-level completes, mark a
line and label as ‘B’. Repeat two more times, labeling lines as ‘C’,
and ‘D’.
4. Measure the vertical distance ‘h’ between the highest and the
lowest points among A, B, C, and D.
5. If h=2mm or less, accuracy is qualified. If h>2mm but <10mm,
adjust the calibration. If h>10mm, please contact an authorized
service center or dealer for repair.
Z-Axis Accuracy Check:
1. Place the instrument
into the vertical
position, using
vertical mount
bracket included.
Power on the unit
and allow to auto level. Measure the height of H2 between the
horizontal laser line and the platform.
2. Mark a point ‘0’ under point 0, which is (H1-H2). Point ‘0’ is a
reference point for the Z-axis.
3. Project the laser to the vertical line on the wall and measure the
distance “h” between the projected point and the point ‘0’.
4. If h< 2mm, the accuracy is qualified. If h> 2mm but < 10mm, the
accuracy is beyond tolerance and calibration is required.
If h > 10mm, please contact an authorized service center or
dealer for repair.
1. Power off the instrument and face the X-axis to the wall.
2. Press and simultaneously, and then release while still
pressing for approximately ten seconds. The instrument will
then enter Calibration mode, and ‘CAL’ will be displayed.
3. Using the remote control, press the button to select the axis to
be calibrated.
4. On the remote, press the buttons to move the laser line
up and/or down, until the laser line hits directly on reference
point ‘0’.
Calibration Confirm:
Press the button to confirm the calibration value after calibration
is completed. Instrument will return to normal operation mode.
Note: In the self-check and calibration mode, self-calibration
coefficient is from 1600-2495. If user calibrates in this range,
and accuracy is still not achievable, please contact an authorized
service center or dealer for repair.
• After calibration is complete, user must turn the instrument
off and then back on. Calibration is then complete.
• When calibrating, the user must check accuracy of both the
X and Y-axis, until both are within accuracy specification.
Accuracy Calibration of the Z-Axis:
Place the instrument horizontally, and enter the self-calibration using
the same method as for the X and Y-axis calibration. Adjust the
projected laser point to make it coincide with point ‘0’.
• This laser unit is a precision tool that must be handled with care.
• Avoid exposing unit to shock vibrations and extreme temperatures.
• Before moving or transporting the unit, make sure that the unit is turned off.
• Remove the batteries when storing the unit for an extended time (more than
three months) to avoid damage to the unit should the batteries deteriorate.
• Always store the unit in its case when not in use.
• Avoid getting the unit wet.
• Keep the laser unit dry and clean, especially the laser output window.
Remove any moisture or dirt with a soft, dry cloth.
• Do not use harsh chemicals, strong detergents or cleaning solvents to clean
the laser unit.
