Setup
1. Battery Installation
- Locate the battery compartment on the back of the clock.
- Remove the battery compartment cover.
- Insert two (2) new AAA batteries (not included) according to the polarity indicators (+ and -) inside the compartment.
- Replace the battery compartment cover.
Image: The rear view of the clock displays the battery compartment and clearly labeled control buttons for easy setup and adjustments.
2. Initial Power On and Atomic Time Synchronization
Upon battery installation, the clock will automatically attempt to synchronize with the atomic time signal. This process may take several minutes to several hours, depending on your location and signal strength. The atomic signal icon (a radio tower with waves) will flash during synchronization and become solid once a successful signal is received.
Image: The clock is shown mounted on a wall, displaying the time and the atomic signal icon, indicating automatic time synchronization.
3. Setting Time Zone and DST
Even with atomic synchronization, you may need to manually set your time zone and Daylight Saving Time (DST) preference.
- Press the SET button (often represented by a gear icon) on the back of the clock to enter setup mode.
- Use the UP and DOWN buttons (arrow icons) to adjust the time zone.
- Press SET again to move to the DST setting. Use UP or DOWN to toggle DST On or Off.
- Continue pressing SET to cycle through other settings or exit setup mode.
4. Placement Options
The clock can be placed on a flat surface or mounted on a wall.
- Desktop Placement: The removable stand is stored in the battery compartment. Gently pull it out and attach it to the designated slot on the back of the clock to allow it to stand upright on a desk or shelf.
- Wall Mounting: Use the keyhole slots on the back of the clock to hang it securely on a wall using appropriate screws or hooks (not included).

Maintenance
1. Battery Replacement
When the display becomes dim or the clock stops functioning, it is time to replace the batteries. Follow the battery installation steps in the Setup section. Always replace both AAA batteries simultaneously with new ones.
2. Cleaning
To clean the clock, wipe it gently with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these may damage the display or casing.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Clock not displaying / Display is dim | Dead or low batteries; Incorrect battery installation. | Replace with new AAA batteries, ensuring correct polarity. |
| Atomic signal icon is flashing or not appearing | Weak signal due to location (e.g., near electronics, metal structures, or far from transmitter); Interference. | Move the clock to a different location, preferably near a window and away from electronic devices. Allow several hours for synchronization. If signal remains weak, manually set the time. |
| Incorrect time displayed | Incorrect time zone setting; DST setting incorrect; Atomic signal not received or incorrect. | Verify time zone and DST settings. Ensure atomic signal is strong. If necessary, manually set the time. |
| Temperature/Humidity readings seem inaccurate | Clock placed near heat sources, vents, or in direct sunlight; Sensor obstruction. | Relocate the clock to an area with stable ambient temperature and humidity. Ensure sensors are not blocked. |
| Alarm not sounding | Alarm not activated; Alarm volume too low (if adjustable, though this model does not specify volume control). | Ensure the alarm icon is visible on the display, indicating it is active. Re-set the alarm time. |
