- Placement: Place the alarm clock on a stable, flat surface away from direct sunlight, heat sources, and excessive moisture.
- Battery Backup: The internal backup battery (if applicable) is designed to maintain time settings during brief power outages. If the clock frequently loses time after power interruptions, the backup battery may need replacement by a qualified technician.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Clock display is off or unresponsive. | Power disconnected; unit in standby mode. | Ensure power adapter is securely plugged in. Press the power button on the back to activate the display. |
| Wireless charging is not working or slow. | Device not centered; incompatible device; phone case too thick; phone heating affecting charging. | Reposition device on the charging pad. Remove thick phone cases. Ensure device is Qi-compatible. Allow phone to cool if overheating. Note that some phones may not charge to 100% or may discharge slightly after reaching full charge due to trickle charging behavior. |
| USB-C charging is not working. | Cable issue; device drawing too much power. | Try a different USB-C cable. Ensure the device is compatible with 5V=1A charging. |
| Temperature display is inaccurate. | External heat source; phone on charging pad generating heat. | Move the unit away from heat sources. Remove phone from wireless charging pad if accurate temperature reading is desired. |
| Display brightness changes automatically or turns off. | Interference from charging device on touch-sensitive area. | Ensure no objects are interfering with the touch-sensitive brightness control area, especially when a phone is charging wirelessly. |
| Slight whistling sound from the unit. | Normal operational noise for some electronic components. | This is generally not a fault. If the sound is excessively loud or changes, contact support. |
