5. Maintenance

• Cleaning: Use a soft, dry cloth to clean the clock's surface. Avoid abrasive cleaners or solvents that may damage the finish.
• Backup Battery: Replace the AAA backup battery annually or if you notice settings are not retained during power outages.
• Power Cable: Ensure the power cable is not bent, twisted, or damaged.

6. Troubleshooting

• Clock not powering on: Ensure the USB power cable is securely connected to both the clock and a functional 5V/1A or 5V/2A DC power adapter, which is plugged into a live wall outlet.
• Screen is off: If the clock is only powered by the backup AAA battery, the screen will remain off. It requires continuous DC power for the display to function.
• Alarm not sounding: Alarms will not sound when the clock is operating solely on backup battery power. Ensure the clock is connected to its primary DC power source.
• Incorrect time/date: Verify that the time and date settings are correctly configured using the remote control. Check if DST is enabled or disabled as desired.
• Remote control not working: Check the battery in the remote control and replace if necessary. Ensure there are no obstructions between the remote and the clock's sensor.
