levels the laser beam elevation changes by more than 1/8 in. (2.5 mm), the
HI alert shuts down the laser and rotor, and the status LED flashes red two
times per second (twice the manual-mode rate).
2. To turn off the laser, press and hold the power button for three seconds.
Selecting the Rotation Speed
The laser has three laser beam rotation speeds—300, 600, and 900 rpm. The
rotation speed can be changed at any time to meet your job-site conditions.
Use 600 rpm for held-held receivers and most machine-control systems.
The rotation speed can also be changed using either of the radio remote
controls. The rotation speed appears in the two-way radio remote control’s
LCD. If you’re using a one-way radio remote control, you must look at the
laser’s LCD for this information. For more information about using the radio
remote control, see the operator’s manual.
1. Repeatedly press and release the rotation-control button until the desired
rotation speed appears in the LCD.
Note: The selected rotation speed briefly appears in the LCD. After a few
seconds, the selected percentage of grade appears in the LCD.
Changing the Grade Value
The grade value for both axes can be changed using two methods—standard
and quick-change. The standard method is used for entering small changes
in the grade value. The quick-change method is used for setting grade to
zero and entering large changes in the grade value.
The grade value can also be changed using either of the radio remote
controls. The grade value appears in the two-way radio remote control’s
LCD. If you’re using a one-way radio remote control, you must look at the
laser’s LCD for this information. For more information about using the radio
remote control, see the operator’s manual.
