5.
Turn the tightening knob (Figure Ⓕ ④) clockwise
to secure the clamp to the level staff, pole, or
similar object.
6.
Loosen the clamp to move the detector up or down
to detect the Reference Level (Figure Ⓕ ⑤).
7.
Once the Reference Level is found, turn the
tightening knob clockwise to hold the clamp in
position.
8.
Read the position shown at the Reference Line
edge of the clamp (Figure Ⓕ ⑥).
Operating the Detector
Turning the Detector ON
1.
On the front of the detector, press to turn the
detector ON.
2.
On the keypad, make sure lights up
(Figure Ⓓ ⑧). You should also hear a short tone.
3.
Use the detector.
Turning the Detector OFF

On the front of the detector, press to turn the
detector OFF.
NOTE: The detector will automatically turn OFF
after it does not detect a laser beam for 10 minutes.
2.
To turn the detector ON again, press .
Adjusting the Accuracy
When powered ON, press to toggle the
detector's accuracy setting between HIGH and LOW.

Accuracy
Setting
LED Use When
HIGH
(≤ 1mm)
High accuracy is required.
LOW
(≤ 2mm)
• High accuracy is not required.
• A stable reference level
cannot be obtained due to
vibrations.
• Heat haze interferes with the
laser beam.
Adjusting the Speaker Volume
When you power ON the detector, the volume will
default to LOUD. To change the volume to SOFT or
MUTE, press to toggle through the volume settings
(LOUD/SOFT/MUTE).
Detecting the Reference Level
1.
While powered ON, position the detector where the
laser beam is projected.
2.
Use the detector’s level vial (Figure Ⓓ ②) to
maintain a level plane.
3.
Within 40° of the laser beam source, point the
reception window (Figure Ⓓ ③) toward the laser
beam.
