The unit will beep twice to indicate the unit is in manual slope mode. Note that the unit will not self-level when in the manual slope mode. Use the slope control buttons located on the lower portion of the keypad to move the beam up or down to the desired slope angle. While in the manual slope function, the tool can be operated in the point, dither or rotation modes. When the beam reaches its minimum or maximum allowable slope, a continuous beep sound is heard on further key press.
