Maintenance
To ensure the longevity and optimal performance of your Zgrmbo Digital Wall Clock, follow these simple maintenance guidelines:

- Placement: Avoid placing the clock in direct sunlight or near extreme heat sources, as this can affect the display's lifespan and temperature sensor accuracy.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
