Standby mode is a power-saving feature that conserves laser battery life.
Press and hold the laser's or remote control's manual button for 3 seconds to activate standby mode.
Note: When standby mode is activated, the laser beam, rotor, self-leveling system, and LEDs shut
down, but the HI alert remains activated.
To let you know that the laser is in standby mode, the battery LED flashes every 4 seconds and dashed lines
appear in the laser's and remote control's LCD.
To deactivate standby mode and restore full operation of the laser, press and hold the laser's or remote control's
manual button for 3 seconds.
The laser and all other functions turn on again.
Using the Manual Mode
Manual horizontal
Pressing the manual button on the laser or the remote control changes the laser from automatic
self-leveling mode to Manual mode. Manual mode is indicated by the flashing (once every second) red
LED 5 plus scrolling horizontal segments appear in the LCD.
In Manual mode (horizontal), the Y(/)-axis can be sloped by pressing the Up- and Down-Arrow-buttons on
the laser's keypad or the remote control. Additionally, the X(y)-axis can be sloped by pressing the Left- and
Right-Arrow-buttons on the laser or remote control.
In vertical mode, the up and down arrow buttons align the laser beam to the right/left side, and the left and
right arrow buttons adjust the slope of the laser beam.
To resume automatic self-leveling mode, press the manual button again.
Mask Mode
Mask Mode – permits turning off the laser beam (electronic shutters) in up to 3 lighthouse windows. Mask
Mode is used when multiple lasers are on the jobsite and they are interfering with each other's receiver.
Regardless of a horizontal or vertical setup, the mask mode for +/-Y- or +/-X-axis is selected by pressing the
manual button in sequence with one of the arrow buttons. Pressing the up or down arrow button in sequence
with the manual button will activate/deactivate the mask mode for the + or – Y axis. To activate the mask
mode on the +Y-axis, press the up arrow button at the laser or remote control, then within <1 second press
and release the Manual button. To activate the mask mode on the -Y-axis, follow the same sequence only
start with the down arrow button.
The right or left arrow button in sequence with the manual button will activate/deactivate the mask mode for
the + or – X axis accordingly.
To indicate which side of the laser the beam has been turned off, the bars on the same side of the mask mode
symbol are turned off.
Note: The unit always powers up with the mask mode deactivated (default).
Y(/)- or X(y)-Axis Slope Mode
Changing the Grade Value of the Y (/)- and X (y)-Axes
Note: The laser automatically self-levels up to +/-9% grade from a leveled tripod.
Tilt the laser towards the up-grade direction for larger grades to make sure the laser is inside its self-leveling
range.
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.
To activate the grade change mode, press and hold one of the arrow buttons; a single beep confirms the
grade change mode has been entered. The single slope laser GL412 grade value can only be changed on the
Y (/)-axis using the up and down arrow buttons.
