- Assemble Solar Panel: Attach the solar panel to either the ground stake or the wall-mount bracket using the provided screws. Ensure the solar panel is securely fastened.

4. Operating Instructions
- Power On/Off: Locate the 'ON/OFF' button on the back of the solar panel. Press it to turn the lights on or off. The lights will only illuminate in dark conditions when the solar panel is covered or at night.
- Select Lighting Mode: Press the 'MODE' button on the back of the solar panel to cycle through the 8 available lighting modes (Combination, In Waves, Sequential, Slow Glow, Chasing, Slow Fade, Twinkle/Flash, Steady On). The built-in memory function will save your last selected mode.
- Automatic Operation: Once powered on and a mode is selected, the lights will automatically turn on at dusk and turn off at dawn, provided the solar panel receives sufficient sunlight during the day.
- Daytime Testing: To test the lights during the day, cover the solar panel completely. The lights should illuminate if the battery has a charge and the unit is powered on.

5. Maintenance
- Solar Panel Cleaning: Regularly wipe the solar panel with a soft, damp cloth to remove dust, dirt, or debris. A clean panel ensures maximum sunlight absorption and charging efficiency.
- Weather Resistance: The light string and solar panel are IP65 waterproof, designed to withstand rain, sun, and snow. However, avoid submerging the unit in water.
- Wire Handling: The copper wires are delicate. Handle them with care during installation and adjustment to prevent breakage or tangling.

6. Troubleshooting
- Lights Not Turning On:
- Ensure the 'ON/OFF' button is in the 'ON' position.
- Verify the solar panel is receiving adequate direct sunlight (6-8 hours) for charging.
- Check if the solar panel is covered or if it is dark enough for the lights to activate automatically.
- Lights Dimming or Short Operating Time:
- The solar panel may not be receiving enough direct sunlight. Relocate it to a sunnier spot.
- The battery may not be fully charged. Allow for a full day of charging before expecting 10-14 hours of illumination.
- Ensure the solar panel is clean and free from obstructions.
- Physical Damage to Wires:
- The copper wires are thin and can tangle or break if not handled carefully. Inspect for any visible damage.
- Note that these units are not designed to connect multiple strings to a single solar panel. Each string light set operates independently with its own solar panel.
