1. Introduction
Thank you for purchasing a UNI-T Laser Level. This manual provides essential information for the safe and correct operation of your device. Please read it thoroughly before use and keep it in an easily accessible place for future reference.
The UNI-T Laser Level is a versatile tool designed for various leveling tasks, offering high precision and multiple line configurations (12 or 16 lines, 3D 360° coverage) with a bright green laser beam. It features self-leveling capabilities, a manual mode for angled projections, and remote control functionality for enhanced convenience.
2. Safety Guidelines
Warning!
- This is a Class 2 laser product.
- Maximum output power: 30mW (for LM576LD/LM585LD/LM573LD-II) or ≤1mW (for LM575LD).
- Wavelength: 520±5nm (for LM576LD/LM585LD/LM573LD-II) or 500nm-540nm (for LM575LD).
Laser Radiation Precautions:
- Do not stare into the laser beam.
- Do not directly expose your eyes to the laser beam.
- Avoid using optical instruments (e.g., binoculars, telescopes) to view the laser beam, as this can intensify the beam and cause eye damage.
- Do not point the laser to eyes.
- Exposure to Class 2 lasers for no more than 2 seconds is generally considered safe due to natural eyelid reflexes (blinking) providing adequate protection. However, direct exposure should always be avoided.
General Cautions:
- Do not disassemble the laser instrument without authorization.
- Do not refit or modify the instrument in any way, as this may cause harmful laser radiation exposure and invalidate the warranty.
- Do not use the laser instrument around children or allow them to use it.
- Some product kits include glasses. These are not safety glasses; they are only intended to help users recognize the laser beam in strong ambient light or when the laser source is distant. They do not protect against direct laser exposure.

5. Setup
Battery Installation:
To install the lithium battery pack:
- Locate the battery compartment, usually at the back or bottom of the device.
- Open the battery door (item 5 in LM576LD/LM575LD diagram, item 8 in LM585LD diagram).
- Insert the 5200mAh lithium battery pack, ensuring correct polarity.
- Close the battery door securely.
The device can be charged via the Type-C charging interface (item 6 in LM576LD/LM575LD diagram, item 9 in LM585LD diagram).
6. Operation
Self-Leveling Mode:
- Ensure the laser instrument is in the locked state.
- Toggle the pendulum lock (item 7 in LM576LD/LM575LD diagram, item 6 in LM585LD diagram) to the unlocked position. This initiates self-inspection.
- After self-inspection, the horizontal laser line will be continuously on, and the instrument will be in self-leveling mode.
- If the instrument is within its self-leveling range of ±(3±1)°, it will automatically level.
- If the tilt angle exceeds the self-leveling range, the laser line will flash quickly, and a beeping sound will be emitted.
Line Selection:
- Press the 'H' button to turn on/off the horizontal laser line.
- Press the 'V' button to turn on/off the vertical laser line.
- Horizontal and vertical laser lines can be used independently or simultaneously.
- For LM573LD-II, continuously press the 'V' button to cycle through operating modes: 1# vertical plane, 2# vertical plane, two vertical planes simultaneously. Press 'H' to switch to horizontal plane or generate a horizontal plane.
Manual Mode (Slash Function):
- In the shutdown state, press and hold the 'V' button for more than 3 seconds to enter manual mode. The instrument will turn on and emit a horizontal laser line.
- The lock indicator will remain on, and the laser line will flash once every five seconds to indicate manual mode.
- In manual mode, the laser line can be set at different angles (e.g., 180° slash function with a tripod).
- To exit manual mode, press and hold the 'V' button again for more than 3 seconds, or toggle the pendulum lock to enter self-leveling mode and then toggle it again to shut down.
- Note: The laser line in manual mode cannot be used as a horizontal/vertical reference line for precise leveling.
Pulse Mode (Outdoor Mode):
- In self-leveling mode, long press the 'V' button to enter outdoor pulse mode. The pulse indicator will be on, and the laser line brightness will decrease.
- In this mode, the instrument can work with a dedicated laser receiver (not included).
- Long press the 'V' button again to exit pulse mode.
- For LM585LD, when the instrument is ON, short press the manual/pulse button to enter pulse mode. The brightness of the laser beam will decrease and the pulse indicator light will turn blue. Short press again to exit.
Remote Control Mode:
This product is equipped with a remote control for switching functions.
- Pairing: For first-time use, turn on the instrument, then press and hold the 'H' button on both the instrument and the remote control simultaneously for more than 3 seconds to pair successfully.
- Usage: The remote control can only switch functions (e.g., horizontal/vertical lines) and cannot remotely turn on/off the instrument or control pulse mode.
- Note: The remote control function is only active after the instrument has been turned on.
Power Off:
In the power-on state, toggle the pendulum lock to the locked position again to turn off the instrument.
Note: Always toggle the pendulum lock to the locked position before shutting down the instrument to protect the pendulum mechanism.
Charging and Power Indicators:
- When the instrument is in use, the charging/power indicator is off.
- When battery power is 20% or less, the indicator will flash red, and the instrument will automatically shut down when fully discharged.
- While charging, the indicator will flash red.
- When fully charged, the indicator will switch to a steady green light.
- If charging directly via the instrument's charging interface, the green light will flash during charging and become steady green when fully charged.
7. Maintenance
- When not in use, turn off the instrument and slide the lock switch to the locked position.
- Do not short-circuit the battery contacts or expose batteries to fire.
- Avoid storing batteries in high-temperature environments or direct sunlight.
- Clean the exterior plastic parts with a damp cloth. Do not use solvents.
- Wipe the instrument with a dry and soft cloth before storage.
- Store the instrument in its soft case or plastic box when not in use.
- Do not dispose of the instrument near household waste. Dispose of the lithium battery pack and discarded instruments according to WEEE directives or relevant local regulations.
8. Troubleshooting
This section addresses common issues you might encounter:
- Laser Line Flashing and Beeping: This indicates the instrument is outside its self-leveling range (±(3±1)°). Adjust the instrument's position until it is on a more level surface.
- No Laser Line: Check if the pendulum lock is in the unlocked position for self-leveling mode. Ensure the battery is charged and properly installed. If in manual mode, ensure it was activated correctly.
- Remote Control Not Working: Ensure the instrument is turned on. Re-pair the remote control by pressing and holding the 'H' button on both the instrument and remote for 3 seconds.
- Dim Laser Line in Pulse Mode: This is normal behavior for pulse mode, designed for use with a laser receiver.
- Charging Indicator Flashing Red: The battery is low or currently charging. It will turn steady green when fully charged.
