Setup
Power Connection
The JALL Digital Alarm Clock is powered via the included USB to barrel power cord. It is not designed to operate solely on batteries for its main functions. Batteries (1 CR2032, not included) are typically used for memory backup in case of power loss.
- Connect the small barrel plug of the power cord into the DC IN port on the back of the alarm clock.
- Plug the USB end of the power cord into a standard USB power adapter (not included) or a powered USB port.
- The display will light up, indicating the clock is receiving power.

Initial Settings (Time, Date, Temperature Unit)
Upon first power-up or after a power interruption without backup battery, you may need to set the time and other preferences. Refer to the buttons on the back of the clock (usually labeled SET, UP, DOWN).
- Setting Time: Press and hold the SET button to enter time setting mode. Use UP and DOWN buttons to adjust hours, then minutes. Press SET to confirm each step.
- 12/24 Hour Format: While in time setting mode, you can usually toggle between 12-hour and 24-hour formats by pressing the UP or DOWN button when the hour is flashing.
- Temperature Unit: Press the DOWN button (or a dedicated TEMP button if available) to switch between Celsius (°C) and Fahrenheit (°F) display for temperature.

Snooze Function

Temperature and Humidity Display
The clock continuously monitors and displays the indoor temperature and relative humidity, acting as a useful environmental monitor for your space.

Sound Control Mode (Optional)
Some models may feature a sound control mode where the display turns off and only activates when a sound (like a clap) is detected or the clock is touched. Refer to your specific model's instructions for activating this feature, if available.
Maintenance
- To clean the clock, gently wipe the surface with a soft, dry cloth.
- Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the finish or internal components.
- Keep the ventilation openings clear of dust and debris.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Clock display is off or flickering. | No power or loose connection. | Ensure the USB power cord is securely connected to both the clock and a working power source. Check the power adapter. |
| Alarm does not sound or is too quiet. | Alarm not set correctly, volume too low, or heavy sleeper. | Verify alarm settings (time, mode). Ensure the alarm volume is set to an audible level (if adjustable). Consider placing the clock closer to the bed. Note: Alarm volume is not adjustable on all models. |
| Lowest brightness setting (L1) does not work. | Potential manufacturing variation. | This can be a known characteristic for some units. Use the next brightness level (L2) which is typically still dim enough for most environments. If this is a significant concern, contact customer support. |
| Temperature/Humidity readings seem inaccurate. | Clock exposed to direct sunlight or heat sources. | Relocate the clock away from direct sunlight, heating vents, or other sources of heat/cold that could affect sensor readings. Allow time for the readings to stabilize in the new location. |
