5. Maintenance
5.1 Cleaning
To clean the device, gently wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or immerse the device in water.
5.2 Battery Replacement
The pre-installed CR2032 battery is for memory backup only. If settings are not retained after a power outage, the battery may need replacement. Open the battery compartment (usually on the bottom) and replace with a new CR2032 battery, observing polarity.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Not connected to power, or power adapter faulty. | Ensure the USB-C cable is securely connected and the power adapter is working. Try a different USB port or adapter. |
| Alarm does not sound during a power outage. | The CR2032 battery only retains settings, it does not power the alarm function. | This is normal operation. The device requires continuous external power for full functionality, including alarm sound and light. |
| Settings are lost after power disconnection. | CR2032 backup battery is depleted or incorrectly installed. | Replace the CR2032 battery, ensuring correct polarity. |
| Difficulty setting time/alarms with buttons. | Unfamiliarity with multi-function button operations (short press vs. long press). | Refer to the detailed instructions in the full manual for specific button functions and timing. Practice the different press durations. |
| Light or sound functions not working as expected. | Incorrect settings or temporary software glitch. | Check all relevant settings (brightness, volume, timer). Disconnect and reconnect power to perform a soft reset. |
