5. Daylight Saving Time (DST)

The clock is designed to automatically adjust for Daylight Saving Time. Ensure the DST feature is enabled in the settings if you reside in an area that observes DST.

Maintenance

1. Charging the Battery

Recharge the clock when the low battery indicator appears. Use the provided USB cable and a 5V2A USB charging adapter. A full charge can last for several months depending on backlight usage.

2. Cleaning

To clean the clock, gently wipe the display and casing with a soft, dry, or slightly damp cloth. Avoid using abrasive cleaners or solvents, as these can damage the surface.

Troubleshooting

• Clock not charging: Ensure the USB cable is securely connected to both the clock and a working 5V2A USB charging adapter. Try using a different USB cable or adapter to rule out a faulty component.
• Atomic time not syncing: Place the clock near a window or in an open area away from electronic interference. The atomic signal (WWVB) is strongest at night. If synchronization fails, you may need to set the time manually. Note that atomic signals may not be available in all regions (e.g., outside North America).
• Display segments missing or incomplete: If parts of the numbers or letters on the display are not showing correctly, try restarting the clock by turning it off and on using the power switch on the back. If the issue persists, contact customer support.
• Backlight too bright or too dim: Adjust the backlight brightness settings as described in the 'Operating Instructions' section.
• Incorrect temperature reading: Ensure the clock is not placed near heat sources or in direct sunlight, which can affect the accuracy of the internal temperature sensor.
