Turning On/Off the Laser
1. Press the power button to turn on the laser.
Note: The laser always powers up in the automatic self-leveling mode. If the
laser is out of its self-leveling range and remains out of it for more than 30
minutes, the laser shuts down completely.
Note: When the laser is initially turned on, the LCD shows the approximate
charge of the batteries, the laser beam’s rotation speed, and manual axis-
alignment position if it’s other than zero. After the LCD shows this
information, the last-entered grade immediately appears in the LCD. The
status LED flashes green to indicate that the laser is self-leveling. After the
laser has self-leveled at the indicated grade, the laser beam rotates and the
status LED stops flashing.
Note: After the laser has been level for more than 30 minutes, the HI alert
activates. If the laser is disturbed (tripod bumped, etc.) so that when it re-
levels the laser beam elevation changes by more than 1/8 in. (3.1 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.
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.
