1. Self-Leveling Mode
- Slide the Power/Lock switch to the unlocked position.
- The pendulum is unlocked, and the laser level will self-level within 4 degrees.
- If the device is out of its self-leveling range, the laser lines will flash rapidly to indicate an out-of-level condition.
- Press the power button briefly to cycle through laser line combinations: 360° Horizontal Line, Vertical Line, or both (Cross Line).
2. Manual Mode (Lock Mode)
- Slide the Power/Lock switch to the locked position.
- The pendulum is locked, and the laser lines can be projected at any angle.
- The laser lines will flash every 3-5 seconds to remind you that it is not in self-leveling mode.
- This mode is suitable for tasks requiring angled lines, such as installing handrails or decorative designs.
3. Pulse Mode

- Pulse mode extends the working range of the laser level, especially in bright outdoor conditions or over longer distances.
- To activate pulse mode, press and hold the 'P' button (pulse mode button) on the keypad. The indicator light will turn on.
- When pulse mode is active, the laser level can be used with a compatible Huepar laser receiver (sold separately) to detect the laser beam beyond visual range.
- Press the 'P' button again to deactivate pulse mode.

Troubleshooting
If you encounter issues with your Huepar 901CG laser level, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Laser lines are flashing rapidly in self-leveling mode. | Device is out of its self-leveling range (over 4 degrees tilt). | Place the laser level on a flatter surface or adjust the tripod/mounting to bring it within the self-leveling range. |
| Laser lines are dim or not visible. | Low battery power or bright ambient light. | Replace batteries. For outdoor use or bright conditions, activate Pulse Mode and use a laser receiver. |
| Device does not power on. | Batteries are dead or incorrectly installed. | Check battery polarity and replace with fresh batteries. Ensure the Power/Lock switch is in the unlocked position. |
| Laser lines are not straight or accurate. | Device is in Manual Mode or has been dropped/damaged. | Ensure the Power/Lock switch is in the unlocked position for self-leveling. If accuracy issues persist after a fall, contact customer support for calibration or repair. |
