5. Operating Instructions
- Power On: Press the Power button on the receiver to turn it on. The dual LCD screens will illuminate.
- Volume Adjustment: Use the Volume button to cycle through LOUD, SOFT, or MUTE settings for the audible alert.
- Backlight: Press the Light button to turn the LCD backlight on or off, improving visibility in low-light conditions.
- Detecting the Laser Line:
- Position the receiver in the path of the laser beam. The receiver has detection windows on both the front and back.
- When the laser beam is detected, the LED indicators on the screen will show its position relative to the center mark. An audible alert will also sound if not muted.
- Adjust the receiver's height (by moving it up or down on the measuring rod) until the central indicator on the LCD screen lights up and a continuous tone is heard. This indicates the receiver is precisely aligned with the laser line.
- For fine adjustments, slightly loosen the clamp to move the receiver up or down more easily. Once the laser line is found, tighten the clamp to secure the receiver.
- Precision Adjustment: The receiver offers high and low precision settings. Use the precision button to switch between these modes for more accurate or faster detection as needed.
