To activate ADS, turn off the Manual Mode (if it is ON) by pressing (C), and then press the ADS (B)
button. If after 1 minute, the instrument is disturbed and the ADS light is flashing it is necessary to
check any benchmarks that have been made and ensure the proper "HI" (Height of Instrument).
After the flashing ADS has been reset, by pressing the button one time, you will have an additional
minute to set and check your measurements.
To turn ADS OFF press the (B) button once. This will put the instrument into normal Auto
Self-Leveling mode.
Manual Mode
Manual mode disengages the leveling feature; allowing the instrument to be placed in any position (to
grade). To activate the Manual Mode, Turn off the ADS (if it is on) and then press the MANUAL mode
button. (Note: The instrument should be level and rotating before entering manual mode to eliminate
the possibility of error.) Once the button has been pressed the ADS light will blink three times, pause
and three times again. Press the MANUAL mode button again to return to normal operation. (Note:
When returning to normal operation the unit must be within its leveling range. Re-set the unit to a level
position before pressing the MANUAL MODE button to the off position.
Manual Grade Mode – Dual Axis Grade (LMH600 only)
The dual grade function is ideal for general site grading, checking excavations, landscaping and
drainage, and more (Fig. 9).
Manual grade mode can be activated by placing the automatic leveling sensor in the OFF position.
The selected grade can be as much as a positive or negative 10%.
Pressing the (C) button will deactivate the level sensor. Use the (H) ("MORE") and (I) ("LESS") arrow
buttons, to adjust your desired grade on the Y axis, (J) ("LESS") and (K) ("MORE") for the X axis.
NOTE: If the instrument is bumped or moved while in Manual Grade mode, the instrument will not
re-level itself.
The instrument will react to "MORE" and "LESS" input. Allow the instrument ample time to react to
the input provided, between grade setups or changes (Fig. 10).
Line Position Mode (Model LMH600)
In this mode, the instrument allows you to fine-tune the location of your vertical (plumb) laser line.
For example, if you've established a plumb line and find that the line is slightly off to the left or right
of your target, use Line Position to jog the line into place without moving the entire instrument
(useful for floor and wall tile installation, walls or partitions, etc.). The laser will now remain aligned
to your target even if you enter other modes (Rotation, Spot, Point-to-Point).
Model LMH600
Line Position mode is available when the instrument is placed in the plumbing position (control
panel facing upward). While the instrument is in the plumbing position, it can be used in Rotation,
Sweep or Spot mode. Use the (J) and (K) buttons on the control panel or the remote control to
position the laser reference point (Fig. 13). If in manual mode, the (J) and (K) buttons will position
the reference line, and the (H) and (I) buttons will incline the vertical line.
