2. Setup
2.1 Battery Installation
- Remove the battery cover located on the back of the clock.
- Insert one fresh "AA" alkaline battery into the designated compartment, observing the correct polarity (+ and -).
- For extended battery life (up to 5 years), insert two additional "AA" alkaline batteries into the optional compartments, ensuring correct polarity.
- Replace the battery cover securely.
2.2 Initial Time Synchronization
After battery installation, the clock will automatically attempt to synchronize with the WWVB atomic time signal from Fort Collins, Colorado. This process may take several hours, especially in areas with weak signal reception.
- Place the clock in an area with good reception, ideally near a window and away from large metal objects or electronic devices that may cause interference.
- Avoid placing the clock near electrical appliances, as they can interfere with the atomic signal.
- The clock will automatically adjust for Daylight Saving Time (DST) if enabled.
2.3 Time Zone Selection
The clock features buttons for selecting your time zone. These are typically located near the battery compartment. Refer to the diagram below for button locations.
- Press the appropriate time zone button (e.g., PST, MST, CST, EST) to set your local time zone.
- The clock will then adjust its time display according to the selected time zone once the atomic signal is received.

2.4 Mounting
The clock is designed for easy wall mounting. Use the integrated hanging hole on the back of the clock to secure it to a wall hook or screw. Ensure the mounting surface is sturdy enough to support the clock's weight (approximately 6.3 pounds).

3. Operating Instructions
3.1 Atomic Time Function
Your clock is equipped with an atomic receiver that automatically synchronizes with the WWVB radio signal. This ensures precise timekeeping and automatic adjustments for Daylight Saving Time (DST).
- The clock will search for the WWVB signal daily to maintain accuracy.
- If the signal is lost, the clock will continue to keep time using its internal quartz movement until the signal is re-acquired.

3.2 Manual Time Setting
In rare cases where the atomic signal cannot be received, you can manually set the time:
- Locate the "Manual Set" tab or button near the battery compartment (refer to Image 2.1).
- Use a small tool (like a pen tip) to press and hold the manual set button to advance the hands.
- Release the button when the correct time is displayed.
3.3 Temperature and Humidity Gauges
The clock includes analog gauges for displaying ambient temperature (in Fahrenheit and Celsius) and relative humidity (%RH). These gauges provide local environmental readings.

4. Maintenance
4.1 Battery Replacement
Replace batteries annually or when the clock hands stop moving. If using the 5-year battery option, replace all three batteries simultaneously to ensure consistent performance.
- Remove the battery cover.
- Remove old batteries and dispose of them properly.
- Insert new "AA" alkaline batteries, ensuring correct polarity.
- Replace the battery cover.
4.2 Cleaning
To clean the clock, use a soft, damp cloth. Avoid abrasive cleaners or solvents, as these can damage the finish or the clock face. For outdoor use, periodically wipe down the clock to remove dust and debris.
4.3 Gauge Calibration
The temperature and humidity gauges are factory calibrated. If you suspect inaccurate readings, some models allow for minor adjustments by gently rotating the small calibration screws located on the back of the clock, near the gauges (refer to Image 2.1). Consult a reliable external thermometer/hygrometer for comparison.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Clock hands do not move or stop. | Low or dead batteries. | Replace all batteries with fresh "AA" alkaline batteries. |
| Clock displays incorrect time. | Weak or no atomic signal reception; incorrect time zone setting. |
|
| Temperature/Humidity readings are inaccurate. | Gauges require calibration or are affected by direct sunlight/heat sources. |
