Setup Instructions
- Prepare Numbers: Identify the numbers and letters required for your address. The package includes 3 sets of numbers (0-9) and 1 set of letters (N, S, E, W) to accommodate various address formats (three, four, or five digits).
- Apply Numbers: Carefully peel the adhesive numbers and letters from their backing. Apply them to the white plaque of the address sign. Ensure they are straight and centered for optimal visibility. The high-performance adhesive is designed to prevent curling or falling off.
- Assemble Stake: Connect the ground stake sections if necessary, then attach the assembled stake to the bottom of the address sign unit.
- Select Location: Choose a location in your yard or garden that receives direct sunlight for at least 6-8 hours daily. This is crucial for the solar panel to charge the internal battery effectively. Ensure the sign is clearly visible from the street.
- Install Sign: Firmly push the ground stake into the soil until the sign is stable and at the desired height.
- Initial Charge: Before first use, ensure the sign is placed in direct sunlight for a full day (6-8 hours) to allow the battery to charge completely.

- Check Numbers: Periodically inspect the adhesive numbers and letters to ensure they remain firmly attached and legible.
