1. Setting Time and Date
In clock mode, long-press the "MODE" key to switch between 12-hour and 24-hour time formats. To set the time, press the "SET" key. The hour digits will flash. Use the "Previous/Decrease" and "Next/Increase" keys to adjust the hour. Press "SET" again to move to minutes, then adjust similarly. Continue pressing "SET" to cycle through date settings if applicable (not explicitly mentioned for this model, but common for digital clocks).
2. Setting Alarms
The clock supports setting two alarms. To set an alarm, press the "SET" key until the alarm icon (e.g., 🔔1 or 🔔2) flashes. Use the "Previous/Decrease" and "Next/Increase" keys to adjust the alarm time. Press "SET" to confirm each setting (hour, minute). To activate or deactivate an alarm, press the corresponding alarm button (if available, or cycle through modes with "SET" until alarm on/off option appears). When an alarm rings, press any key to activate the snooze function, which will ring again after 5 minutes (up to 2 times). To stop the alarm completely, press the "SET" key.
3. Bluetooth Speaker Mode
To enter Bluetooth mode, press the "MODE" key until "BT" appears on the display. The clock will enter pairing mode. On your device (smartphone, tablet, etc.), search for "QSMBNTX U-03Q" (or similar name) in the Bluetooth settings and connect. Once connected, you can play audio through the clock speaker.
4. FM Radio Mode
To use the FM radio, ensure the Type-C charging cable is connected, as it acts as an antenna for better reception. Press the "MODE" key until "FM" appears on the display. The clock will automatically scan and save available stations. Use the "Previous/Decrease" and "Next/Increase" keys to switch between saved stations or manually tune.
5. Voice-Activated Function
When the clock speaker is in power-saving mode (display and lights off after a few seconds), it will automatically activate the digital clock display and warm LED lights upon detecting sound of approximately 60dB within 2 meters. This feature helps conserve battery life.

7. Other Audio Inputs (TF Card, AUX)
Insert a TF card into the TF card slot on the back of the device to play audio files directly. For AUX input, connect an audio cable from your external device to the AUX-in port on the back of the clock speaker. Press the "MODE" key to switch to the respective input mode.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the surface of the clock. Do not use abrasive cleaners or solvents.

- Placement: Place the clock on a stable, flat surface away from direct sunlight, heat sources, and excessive moisture.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Battery is depleted. | Connect the Type-C charging cable and charge the device for at least 30 minutes before attempting to power on. |
| Bluetooth connection fails. | Device is not in pairing mode; Bluetooth is off on source device; too far from source device. | Ensure the clock is in Bluetooth mode ("BT" displayed). Turn Bluetooth off and on again on your source device. Move the source device closer to the clock (within 10 meters). |
| FM radio reception is poor. | Charging cable not connected; weak signal. | Ensure the Type-C charging cable is connected, as it functions as an antenna. Try repositioning the clock or the cable for better signal. |
| Alarm does not sound. | Alarm is not activated; volume is too low. | Verify that the alarm is set and activated (check alarm icon on display). Increase the volume level. |
| Voice-activated function not working. | Ambient noise too low; device not in power-saving mode. | Ensure the sound level is above 60dB. The feature only works when the display is off in power-saving mode. |
