User Manual

Note: The laser and control hub #1 must be on one axis, which is at 0%
grade.
3. Enter the approximate grade value for the ∠ axis and 0% for the ∠ axis.
Note: The automatic slope-searching range is ±1.5%. The approximated
grade should be within 1.5% of the final matched grade.
4. Connect a hand-held receiver and radio remote control to a grade rod.
5. Set the grade rod on control hub #1.
6. Slide the receiver up/down the grade rod until the receiver’s LCD
shows an on-grade reading.
Note: The grade rod MUST be plumb.
7. Go to slope-control hub #2 and set the grade rod on the hub. Make
sure you DON’T change the height of the receiver on the grade rod.
8. Select “Grade Match” from the operational menu using the mode
button.
9. Select the axis (∠ or ∠) that you are aligning using the up or down
buttons.
10. Press the enter button to confirm the selection. “Start” then “Wait”
appears in the radio remote control LCD.
11. Hold the grade rod plumb and steady on slope-control hub #2 during
grade matching.
Note: “Grade Matching Complete” appears in the radio remote control LCD
when grade matching has been completed. If grade matching fails, a failure
message appears in the radio remote control LCD. (See the
“Troubleshooting” section of this manual for more information.)
Note: The resultant grade appears in the laser LCD display and on the two-
way remote control LCD display (if used).
Note: Alignment can take 1 to 5 minutes to complete.
Grade-Matching Mode: Two Axes Setup
This function can only be done on one axis at a time. The laser needs to be
aligned with one of the slope-control hubs in automatic axis alignment mode
before dual axes grade-matching mode can be activated.
1. Set up the laser over a reference point.
2. Using the sighting guide as a guide, rough align the laser with the slope-
control hub #1.
Note: The two slope-control hubs must be in lines that are at a 90° angle
from one another.
