Center Lock
Center lock feature is only compatible with certain
RPM's and accuracy settings and is not compatible
with channel link. Some settings may automatically
change when this function is being used.
1. Place the paired receiver in the desired location.
NOTE: The receiver must be aligned with the X
or Y axis of the rotary laser. For best results, use
the iron sight on top of the laser to align directly
with the receiver sensor.
2. Press the grade match button on the receiver.
Select the center lock (crosshair with lock icon)
using the left or right arrow buttons and press the
"OK" button to continue.
3. Use the arrow keys to select the desired axis.
NOTE: Ensure the laser is aligned and in range
of the receiver being used.
4. The laser will begin to search for the receiver.
5. Once the center is found the laser beam will
move with the receiver. Up or down indicators
and number readout will appear while the laser
adjusts in real-time.
NOTE: Ensure to not move the receiver too fast or out
of range, this may create an error, and the process
will have to be repeated. If not found, the red LED
will show on the receiver and "not found" error will
appear on the laser/remote. Press the "OK" button,
and the laser and remote will go to the main menu,
and the laser will start the self-leveling procedure.
After the laser is leveled, press the grade match
button on the receiver and try steps 1 - 4 again until
the center is found.

Grade Match
Grade match is for checking the rise or fall of the
ground between two elevations without complex
calculations needed. Grade match feature is only
compatible with certain RPM's and accuracy settings
and is not compatible with channel link. Some set-
tings may automatically change when this function
is being used.
1. Place the paired receiver in the desired location.
NOTE: The receiver must be aligned with the X
or Y axis of the rotary laser. For best results, use
the iron sight on top of the laser to align directly
with the receiver sensor.
2. Press the grade match button on the receiver, and
press the "OK" button to continue.
3. Use the arrow keys to select the desired axis.
NOTE: Ensure the laser is aligned and in range
of the receiver being used.
4. Press the "OK" button to confirm the selection
and begin the grade match function. The laser will
begin to search for the receiver. Once the laser is
detected on the center of the receiver, the direct
readout and arrow segments and green indicator
LED will flash green to indicate success. The
measured grade will be displayed on the laser and
remote. If failed, the red indicator LED will flash.
Repeat steps above to try again.
Direct Readout and Arrow Indicators
If a laser is sensed, the direct readout, arrow indica-
tors, and indicator LEDs will illuminate to guide the
user in moving the receiver to align the laser with the
center. If no laser is detected, the LEDs, and arrow
indicator will remain off, and the direct readout will
show no value and display "- - -".
• High LED indicator (blue) - Move the receiver loca-
tion up until on center.
• On center LED indicator (green) - The line being
detected from the laser is on center.
• Low LED indicator (red) - Move the receiver location
down until on center.
NOTE: If the laser leaves the sensor, the up or down
arrow segments will begin to cycle, indicating the
direction that the laser was last detected.
Other Receiver Modes
• Sleep Icon - Indicates that the laser is asleep and
must be woken up before grade match or center
lock can be initiated.
• CAL Icon - Will appear on the receiver when laser
is using it for calibration.
Troubleshooting
• Ensure batteries are inserted correctly according to
the +/- polarity marked in the compartment.
• Replace batteries that may be at the end of life.
• Ensure the tool's internal temperature is within speci-
fied operating ranges. If stored in excessive heat or
cold, allow at least 2 hours to acclimate to ambient
temperature before turning on the tool.
• If the receiver screen pauses for a long period of
time, press and hold the power button for 15 seconds
or remove the batteries to reset.
• If attempting grade match and both center lock and
grade match icons flash at the same time, this is an
indication that the function cannot be completed.
Check pairing status and review laser for any warn-
ings that must be cleared before proceeding.
