2. Initial Atomic Time Synchronization

A visual guide illustrating the three steps for initial setup: installing batteries, waiting for WWVB signal reception, and automatic time update.
Upon battery installation, the clock will automatically begin searching for the WWVB atomic time signal. This process may take up to 10 minutes. During signal reception, the backlight will be temporarily disabled to prevent interference. Once the signal is received, the time and date will update automatically.
If the clock does not synchronize within 10 minutes, press the WWVB SEARCH button to initiate a manual search. Ensure the clock is placed near a window for optimal signal reception.
3. Manual Time Zone Setting
The clock supports six time zones: EST, CST, MST, PST, AKST, and HST. To set your time zone:
- Press the TIME ZONE button repeatedly until your desired time zone is displayed.
- The clock will automatically adjust the time according to the selected zone.
4. Daylight Saving Time (DST) Setting
The clock is designed to automatically adjust for Daylight Saving Time. To enable or disable this feature:
- Press the UP / DST button.
- Toggle between AUTO DST ON or OFF. Select OFF if your region does not observe DST.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display or dim display | Dead or incorrectly installed batteries. | Replace batteries with new AA alkaline batteries, ensuring correct polarity. |
| Clock does not synchronize with atomic time (WWVB) | Weak signal due to location or interference. | Move the clock closer to a window. Press the WWVB SEARCH button to manually initiate signal reception. Avoid placing near electronic devices that may cause interference. |
| Incorrect time displayed | Incorrect time zone selected or DST setting. | Verify the correct time zone is selected using the TIME ZONE button. Check the DST setting with the UP / DST button. |
| Temperature/Humidity readings seem inaccurate | Clock placed near heat/cold sources or in an area with poor air circulation. | Relocate the clock to a central area away from direct sunlight, vents, or appliances. Allow time for readings to stabilize. |
