Maintenance
To ensure the longevity and optimal performance of your GOLOZA Digital Alarm Clock, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to wipe the clock's surface. Avoid abrasive cleaners, solvents, or spray cleaners, as they may damage the display or casing.
- Placement: Place the clock on a stable, flat surface. Avoid direct sunlight, excessive heat, or moisture, which can affect performance and display clarity.
- Non-slip Design: Please tear off the plastic covering the bottom rubber sticker before use. This will help keep the clock securely in place and protect your tabletop.
Troubleshooting
If you encounter any issues with your GOLOZA Digital Alarm Clock, please refer to the following table for common problems and their solutions:
