Reversing the Grade
(One-Way and Two-Way Radio Remote Controls)
The sign of the ∠ axis can be changed using the one-way or two-way radio
remote control.
1. Set up the laser. Turn on the laser and flip its antenna up.
2. Turn on the radio remote control and make sure its antenna is pointing
skyward.
3. Select “Grade Reverse” from the menu using the mode button.
4. Press the enter button to confirm the selection.
Note: On a one-way radio remote control, “Reversing” appears in the radio
remote control’s LCD to indicate that the process is occurring and the sign
of the ∠ axis will be changed on the laser’s LCD.
Note: When grade reversing has been completed, “Grade Reversing
Complete” appears in the LCD. If “Grade Reversing Unconfirmed” appears
in the LCD, check the distance between the laser and radio remote control
and try reversing the grade again.
Note: On a two-way radio remote control, the sign of the ∠ grade value
reverses to indicate that grade reversing has been completed.
