4. The laser and remote default into channel (CH1) 1. The remote
control will only work when the laser and remote are on the same
channel. If other lasers are in the area, the remote and laser can
be changed from CH1 to CH9 and CHA to CHF making it so the
remote will only work for a specific laser. To change the remote
channel, press the remote button.
5. If the LCD on the laser displays the remote is not turned on, is
too far away from the laser or is on a different channel.
6. If the LCD displays on the laser and remote, the remote and
laser are on the same channel.
Note: The battery symbol display on the remote shows the battery
strength of the remote batteries and not the laser battery strength.
The differences between the remote button and laser buttons are
as follows:
1. Holding the on the remote Level/Backlight for three seconds
will turn on the remote backlight. To turn off the backlight, hold
the same button in again for another three seconds.
2. One press of the manual button will put the laser in “sleep”
mode. All the laser settings will be saved on the laser. The only
button that will work on the laser is the power button. The
only buttons that will work on the remote is the manual
button and power button. Another press of the manual
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.

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.
Accuracy Calibration of the X and Y-Axis:
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’.
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.
