5. Setup
5.1 Battery Installation
- Open the battery compartment cover on the laser level.
- Insert the 5200mAh Li-ion battery, ensuring correct polarity.
- Close the battery compartment cover securely.
- For the LRXG receiver, open its battery compartment and insert the 4x AAA batteries, observing polarity.
5.2 Charging the Battery
Connect the Type-C cord to the laser level's charging port and the other end to the 5V/2A adapter. Plug the adapter into a power outlet. The charging indicator will show the battery status. The laser level can also be used while charging.

6. Operating Modes
6.1 Power On/Off
Slide the power switch to the 'ON' position to power on the device. Slide to 'OFF' to power off.
6.2 Self-Leveling Mode
When the power switch is in the 'ON' position, the laser level enters self-leveling mode. The device will automatically level itself within a ±3° range. If the device is tilted beyond this range, the laser lines will flash rapidly and an audible alarm will sound, indicating that it is out of level. Reposition the device on a flatter surface until it self-levels.
6.3 Manual Mode
To activate manual mode, slide the power switch to the 'OFF' position. In this mode, the pendulum is locked, allowing you to project laser lines at any desired angle. The laser lines will flash every 5 seconds to remind you that self-leveling is off. This mode is ideal for angled layouts such as stairs or diagonal installations.
Image 6.1: Self-Leveling Mode automatically provides a horizontal reference. Manual Mode allows for angled layouts.
6.4 Pulse Mode (Outdoor Use)
Activate Pulse Mode for use with the LRXG laser receiver in bright outdoor conditions or over longer distances. This mode extends the working range up to 165ft (50m). The LRXG receiver is dual-purpose, also functioning as a remote control.
Image 6.2: Pulse Mode allows for extended range and outdoor visibility with the LRXG receiver.
6.5 Auto-Tracking Motorized Base & Remote Control
The auto-tracking feature, combined with the LRXG receiver's remote control function, allows for precise fine adjustment of the laser lines without physically touching the device. This is particularly useful for one-person operations and maintaining a fixed cross-point reference.
- Ensure the laser level is in Self-Leveling Mode.
- Press the 'Auto Align' button on the LRXG receiver.
- The motorized base will begin rotating counter-clockwise, sweeping through a 16° range. During this process, the LED on the power button will blink slowly, accompanied by a slow "beep-beep" sound, indicating calibration is in progress.
- Once the sound stops, it means the receiver has detected the laser and the beam is aligned to the center. Calibration is complete, and the LED will remain solid (steady on).
Notes & Warnings for Auto-Alignment:
- Auto eccentric rotation only works in Self-Leveling Mode. It is not available in Manual Mode.
- Avoid reflective surfaces like glass during auto alignment, as stray light may interfere with calibration.
- If the device is bumped or moved during auto alignment, a collision alert will be triggered. The laser will flash three times, and the system will automatically exit auto alignment mode and return to the previous mode.

Image 6.4: The LRXG receiver serves as both a laser detector and a remote control for the laser level.
7. Brightness Control
The Huepar 703CG-TR offers three brightness levels (30%, 60%, 100%) to adapt to different working environments. Adjust the brightness to optimize visibility in bright conditions or to conserve battery life indoors.

8. Maintenance
- Cleaning: Keep the laser level clean and free of dust and debris. Use a soft, damp cloth to wipe the exterior. Do not use harsh chemicals or abrasive cleaners.
- Storage: When not in use, store the laser level in its hard carry case in a dry, cool place, away from direct sunlight and extreme temperatures.
- Battery Care: For long-term storage, ensure the Li-ion battery is partially charged (around 50%) and remove it from the device if storing for extended periods. Recharge the battery periodically to maintain its health.
- Calibration Check: Periodically check the calibration of your laser level to ensure continued accuracy. Refer to the user manual for specific calibration procedures if needed.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Laser lines are dim or not visible. | Low battery; Bright ambient light; Pulse mode not activated with receiver. | Charge the battery; Adjust brightness to 100%; Activate Pulse Mode and use with LRXG receiver. |
| Laser lines are flashing rapidly and/or alarm sounds. | Device is out of self-leveling range (tilted more than ±3°). | Reposition the laser level on a flatter, more stable surface. |
| Laser lines are not level in Manual Mode. | This is expected behavior in Manual Mode, which is for angled projection. | Switch to Self-Leveling Mode if a level reference is required. |
| Auto-alignment not working or inaccurate. | Not in Self-Leveling Mode; Interference from reflective surfaces; Device moved during alignment. | Ensure Self-Leveling Mode is active; Avoid reflective surfaces; Ensure device is stable during alignment. |
| Receiver not detecting laser lines. | Receiver batteries low; Not in Pulse Mode; Receiver too far or misaligned. | Replace receiver batteries; Activate Pulse Mode on laser level; Ensure receiver is within range and aligned with laser. |
