Working in Manual mode:
In Manual mode the 875G's self-leveling mechanism is disabled
and the laser beams can be set at any slope required.
1. Long press on the M button (#3) will activate the Manual
mode. The laser will project blinking forward cross beams, and
the red LED (#5) will light up.
2. Choose the beams that you want to work with by pressing the
V or H buttons.
3. To mark the slope, tilt the laser to the desired slope.
4. To turn the Manual mode OFF, press the M button (#3) again.
5. If while in Manual mode you turn the pendulum safety lock (#11)
from OFF to ON, it will incapacitate the Manual mode and the
red LED (#5) near the M (#3) button. If the laser level is within
its self-leveling range, the automatic self-leveling feature will be
activated.
