7. Troubleshooting (Q&A)
- Q: Does the clock run on an internal battery?
- A: No, this LED clock requires a 5V/1A USB-A power adapter (sold separately) to operate. It is not a wireless clock. It has an internal super capacitor for memory backup, not for continuous operation.
- Q: Why does the display freeze, flicker, or hum during use or brightness changes?
- A: This usually indicates an unstable or incompatible power adapter. The clock may not be receiving sufficient current to function normally. Please replace it with a standard 5V/1A adapter manufactured by a reputable brand.
- Q: The remote control is not working. What should I do?
- A: 1. Ensure you have removed the transparent battery insulation sheet from the bottom of the remote. 2. When operating the remote, point it towards the infrared sensor at the bottom of the clock. Avoid any obstructions that might interfere with the infrared signal. The effective range is approximately 3.5 meters.
- Q: How do I stop the colon (time separator) from blinking?
- A: Simply press the RIGHT (▶) arrow button on the remote control. This will toggle the colon's blinking on or off.
- Q: Can this clock display in 24-hour format?
- A: Yes. Short press the UP (△) arrow button on the remote control to switch between 12-hour and 24-hour formats.
- Q: Why doesn't the alarm sound at the set time?
- A: Please verify both the alarm time setting and the time format setting (12-hour/24-hour). For 12-hour format: AM12-PM11. For 24-hour format: 0-23.
- Q: How do I display the temperature and switch between Fahrenheit and Celsius?
- A: Short press the LEFT (◀) arrow button to cycle through the display of date, time, or temperature. Once the temperature is displayed, press the TEMP button to switch between Fahrenheit and Celsius.
