Setup
Follow these steps for proper installation of your string lights:

- Solar Panel Placement:
- Choose a location for the solar panel that receives at least 6 hours of direct sunlight daily. This is crucial for a full charge and maximum illumination time.
- You can use the included ground stake to secure the panel in soft ground or the durable clip to attach it to a fence, railing, or other suitable surface. Screws are also provided for permanent mounting.

- Hang the string lights using the integrated hook holes on each bulb socket. You can drape them across a patio, pergola, gazebo, or along a fence.

- Initial Charge: Before first use, ensure the solar panel is exposed to direct sunlight for at least 6-8 hours to allow the internal batteries to fully charge.
Operating Instructions
Your Brightech Ambience Pro Solar Powered Outdoor String Lights are designed for simple, automatic operation:
- Power On/Off: Locate the On/Off switch on the back of the solar panel. Set it to the 'ON' position for automatic operation.
- Automatic Operation: Once the switch is in the 'ON' position and the batteries are charged, the lights will automatically turn on at dusk and turn off at dawn.
- Daylight Sensor: The built-in daylight sensor detects ambient light levels, ensuring the lights only activate when it's dark enough.

Maintenance
To ensure the longevity and optimal performance of your string lights, follow these maintenance tips:
- Clean Solar Panel: Periodically 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.
- Bulb Care: The bulbs are shatterproof plastic and require minimal maintenance. If a bulb becomes dirty, gently wipe it clean. No bulb replacement is typically needed due to the long lifespan of LEDs.
- Battery Lifespan: The internal batteries have a rated lifespan of 1,000 charges. If you notice a significant decrease in illumination time after prolonged use (beyond 2.5 years), the batteries may need to be replaced. This process is typically user-serviceable for some models, but consult Brightech support if unsure.
- Storage: If storing the lights for an extended period, ensure the solar panel is fully charged, then turn the power switch to 'OFF'. Store in a cool, dry place.
