5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the display and exterior. Avoid abrasive cleaners or solvents.
- Storage: When not in use, store the scoreboard in a dry, cool place, away from direct sunlight and extreme temperatures.
- Power Disconnection: Disconnect the power adapter from the wall outlet if the device will not be used for an extended period.
6. Troubleshooting
- Scoreboard not powering on:
Ensure the power adapter is securely connected to both the scoreboard and a working electrical outlet. Verify that the USB cable is properly inserted.
- Remote control not responding:
Check if the AAA batteries in the remote are correctly inserted and have sufficient charge. Point the remote directly at the scoreboard. Ensure no obstructions are blocking the signal path. If multiple scoreboards are in use, ensure they are not interfering with each other.
- Display not visible in bright conditions:
The scoreboard is designed for indoor use. In bright outdoor environments, the LED display may not be clearly visible. Adjust the brightness settings if possible, or relocate to a shaded area.
- Time/Date resets after power loss:
The scoreboard does not have internal clock memory for time and date settings during a power outage. These settings will need to be reconfigured upon power restoration. Stored game records, however, are retained.
