Operating Instructions
The Sunforce Solar String Lights are designed for automatic operation, but can also be controlled manually with the remote.
Automatic Operation:

- Ensure the solar panel is clean and free from obstructions to allow proper light sensing.
Using the Remote Control:
- Power Button: Press to manually turn the lights ON or OFF.
- Mode Button: Cycle through different lighting modes (e.g., steady on, flashing, fading) if available. Refer to the remote's specific markings.
- Timer Button: Activate timer functions (e.g., 4-hour, 6-hour operation) if available.
- Ensure the remote control has working batteries (2 Lithium Ion batteries included).
- Point the remote directly at the solar panel's receiver for best results.
Maintenance

- Inspect Wiring: Periodically check the wiring and connections for any signs of wear, damage, or loose connections.
- Bulb Replacement: If a bulb fails, carefully unscrew the old bulb and screw in a new 0.3W LED replaceable bulb. Ensure the power is off before replacing bulbs.
- Winter Storage: During prolonged periods of non-use or harsh winter conditions, it is recommended to store the lights indoors in a cool, dry place to prolong battery life and product longevity.
