Operating Instructions

1. Powering On/Off:

Press the Power button (usually marked with a circle and vertical line) to turn the receiver on. Press and hold the same button to turn it off.

2. Detecting the Laser Beam:

Hold the receiver with the receiving window facing the rotating laser beam. Move the receiver up or down until the laser beam is detected. The display will show the deviation from the laser plane, and acoustic signals will guide you.

3. Interpreting the Display:

• The digital display shows the exact distance in millimeters (or inches) from the center of the receiving window to the laser beam.
• Arrows on the display indicate whether to move the receiver up or down to reach the laser plane.
• When the laser beam is centered, a solid line or specific indicator will appear, and a continuous tone will sound (if audio is enabled).

4. Adjusting Accuracy Settings:

Press the SET button to cycle through the four available accuracy settings. Choose a coarser setting for quick checks and a finer setting for precise leveling tasks.

5. Acoustic Signals:

Press the Speaker button to toggle the acoustic signals on or off. The tones will change frequency as you approach the laser plane, becoming continuous when centered.

6. Unit Conversion (MM/IN):

Press the MM/IN button to switch between millimeter and inch display units.
