1. Introduction

This manual provides essential information for the safe and effective use of your BEITESI Red Line Laser Module, model 50mw-line-1pack. Please read these instructions carefully before installation and operation. This compact laser module is designed for various applications requiring a precise red line projection, such as targeting, alignment, and signal equipment. It features a red light source, Class II output power (<1mW), operates on 3V-5V DC, and has an adjustable focal length.

2. Safety Information

WARNING: Laser Radiation. Avoid direct eye exposure.

• This product emits Class II laser radiation. Do not stare directly into the laser beam.
• Do not point the laser at people, animals, or reflective surfaces.
• Keep the laser module out of reach of children.
• Use only with the specified voltage range of 3V-5V DC. Using incorrect voltage may damage the device and pose a safety risk.
• Do not attempt to disassemble, modify, or repair the laser module. This can lead to hazardous radiation exposure and will void the warranty.
• Ensure proper ventilation if operating for extended periods in an enclosed space.

3. Setup

3.1 Power Connection

Connect the red wire to the positive (+) terminal and the black wire to the negative (-) terminal of a stable 3V-5V DC power source. Ensure correct polarity to prevent damage to the module.

5. Maintenance

• Cleaning: Keep the laser lens clean. Use a soft, lint-free cloth to gently wipe the lens if dust or debris accumulates. Do not use abrasive cleaners, solvents, or excessive force, as this may scratch the lens.
• Storage: Store the module in a dry, cool environment away from direct sunlight, high humidity, and extreme temperatures.
• Inspection: Periodically inspect the power wires for any signs of damage, fraying, or loose connections. Address any issues promptly to ensure safe operation.

6. Troubleshooting

• No Laser Output:
  • Check power connections. Ensure the red wire is connected to positive (+) and the black wire to negative (-).
  • Verify that the power source is supplying voltage within the 3V-5V DC range.
  • Inspect the power wires for any breaks or loose connections.
• Dim or Unfocused Line:
  • Adjust the focal length by gently rotating the front lens assembly until the line is sharp.
  • Clean the laser lens if it appears dirty or smudged.
  • Ensure the power supply is providing adequate and stable voltage.
