2. Safety Information
Please read all safety instructions before installing and operating the SNL-003 beacon light. Failure to follow these instructions may result in damage to the product or personal injury.
- Installation: Ensure the light is securely mounted to prevent it from falling, especially in marine environments where vibrations or strong winds may occur.
- Water Exposure: While the unit is IP65 rated for water resistance, avoid submerging the unit for extended periods unless specifically designed for such use. Ensure the waterproof push button is properly sealed after mode selection.
- Battery: The internal battery is replaceable. When replacing, use only specified battery types to avoid damage or fire hazards. Do not attempt to open the battery compartment unless performing a battery replacement.
- Solar Panel: Do not cover the solar panel during daylight hours, as this will prevent charging.

4. Setup and Installation
Proper installation ensures optimal performance and longevity of your SNL-003 beacon light.
4.1 Initial Charging
Before first use, place the light in direct sunlight for at least 24-48 hours with the unit turned off. This allows the internal battery to reach a full charge, ensuring maximum performance from the start.
4.2 Mounting Location
Select a mounting location that receives maximum direct sunlight throughout the day. Avoid areas shaded by buildings, trees, or other obstructions. For marine applications, ensure the light is mounted at a height that provides the desired visibility range and is clear of potential obstructions.
4.3 Mounting Procedure
The SNL-003 features an easy flange mounting design. Use appropriate hardware (screws, bolts, etc., not included) suitable for your mounting surface (e.g., wood, metal, concrete).
- Position the light on the desired surface.
- Mark the locations for drilling through the mounting flange.
- Drill pilot holes if necessary.
- Secure the light using suitable fasteners. Ensure the light is stable and cannot be dislodged by environmental factors.

5. Operating Instructions
The SNL-003 beacon light is designed for simple operation with automatic dusk-to-dawn functionality.
5.1 Mode Selection
The light offers two operating modes: Constant-On and Flashing. To select the desired mode:
- Locate the waterproof push button on the underside of the lamp.
- Press the button once to cycle between modes.
- The light will indicate the selected mode (e.g., a brief flash for flashing mode, or continuous light for constant-on mode).
