5. Operating Instructions
5.1 Powering On/Off
Slide the ON/OFF switch to the 'ON' position to power on the device. Slide it to 'OFF' to power off.
5.2 Self-Leveling Mode
When the pendulum is unlocked (ON position), the device automatically enters self-leveling mode. It will self-level within a 3° range. If the tilt exceeds 3°, the laser lines will flash and an audible alarm will sound, indicating that the device is out of level. Adjust the device's position until it is within the self-leveling range.

5.3 Manual Mode
To activate manual mode, long-press the mode button (often labeled 'M' or a similar icon) while the device is powered on. In manual mode, the laser lines can be projected at any desired angle, which is useful for tasks like installing handrails on stairs or other non-level applications. The laser lines will not flash in manual mode, even if the device is tilted beyond 3°.

5.4 Switching Laser Lines
Use the 'V' button to activate/deactivate vertical laser lines and the 'H' button to activate/deactivate horizontal laser lines. You can combine different lines as needed for your project.

5.5 Remote Control Operation
The included remote control allows you to switch laser lines and modes from a distance, up to 33 feet (10 meters), enhancing convenience for large projects.

5.6 Pulse Mode
The device features a pulse emission mode, which can be activated for use with a laser receiver (not included) to extend the working range and improve visibility in bright conditions.
6. Maintenance
- Cleaning: Use a soft, damp cloth to clean the device. Do not use abrasive cleaners or solvents.
- Storage: Store the laser level in its carrying case in a dry, dust-free environment when not in use. Remove batteries if storing for extended periods.
- Calibration: Regular calibration checks are recommended to ensure accuracy, especially after drops or impacts.
7. Troubleshooting
- Laser lines are flashing and alarm sounds: The device is likely out of its self-leveling range (more than 3° tilt). Adjust the position of the laser level until it is within the acceptable range.
- No laser lines: Ensure the device is powered on and the battery is charged. Check if the pendulum lock is in the correct position for the desired mode (unlocked for self-leveling, locked for manual).
- Weak laser lines: The battery might be low. Recharge the battery. Also, ensure you are not operating in excessively bright environments without a laser receiver.
- Remote control not working: Check the remote control's battery. Ensure there are no obstructions between the remote and the laser level.
