4. Setup
4.1 Battery Installation
- Locate the battery compartment cover on the back of the clock.
- Remove the cover.
- Insert the two AA batteries, ensuring the correct polarity (+ and -).
- Replace the battery compartment cover.
4.2 Initial Power-Up and Atomic Signal Reception
Upon battery installation, the clock will automatically power on and begin searching for the WWVB atomic time signal. This process may take several minutes to several hours, depending on your location and environmental conditions. During this time, the signal reception indicator (often a wave icon) will flash.
- For optimal signal reception, place the clock near a window, away from electronic devices that may cause interference.
- The clock is designed to receive signals primarily in North America. Signal strength may vary in other regions.
- Once the signal is successfully received, the time and date will automatically set, and the signal indicator will become solid.

5. Operating Instructions
The clock's display provides the following information:
- Time: Large digits indicate the current time (12-hour format with AM/PM indicator).
- Date: Month and day.
- Day of the Week: Abbreviated day name.
- Temperature: Indoor temperature in Celsius or Fahrenheit.
- Atomic Signal Indicator: Shows the status of atomic signal reception.
5.1 Button Functions
The clock typically has buttons on the back for various settings. Common buttons include:
- SET: Enters or confirms setting modes.
- MODE: Toggles between display modes or setting options.
- WAVE / RCC: Manually initiates atomic signal search.
- TIME ZONE: Selects the desired time zone.
- +/C/F: Adjusts values during setting or switches temperature unit (Celsius/Fahrenheit).
6. Time Zone Setting
To set your local time zone:
- Press the TIME ZONE button. The current time zone will begin to flash.
- Press the + or - button (if available, or MODE/SET) to cycle through the available time zones (e.g., PST, MST, CST, EST, AST, NST, HST, AKST).
- Once your desired time zone is displayed, press the SET button to confirm. The clock will then adjust to the correct time for that zone after receiving the atomic signal.
7. Manual Time Setting
If the atomic signal is consistently unavailable or if you prefer to set the time manually:
- Press and hold the SET button for approximately 3-5 seconds until the hour digits begin to flash.
- Use the + or - button to adjust the hour.
- Press SET again to move to the minute digits, then adjust with + or -.
- Continue pressing SET to cycle through year, month, and day settings, adjusting each with + or -.
- After setting all desired parameters, press SET one last time to exit the manual setting mode.
Note: If the atomic signal is enabled, the clock may attempt to override manual settings once a strong signal is received. To prevent this, you may need to disable the atomic synchronization feature if available (refer to specific button functions on your clock).
8. Maintenance
8.1 Battery Replacement
When the display dims or the clock stops functioning, it is time to replace the batteries. Follow the battery installation steps in Section 4.1. Always use fresh AA alkaline batteries.
8.2 Cleaning
To clean the clock, use a soft, dry cloth. Do not use abrasive cleaners or chemical solvents, as these may damage the clock's finish or display.
9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Clock not setting time automatically | Weak or no atomic signal reception. | Relocate the clock near a window, away from electronic interference. Manually initiate signal search using the WAVE/RCC button. Ensure you are within the WWVB signal range (North America). |
| Incorrect time displayed | Incorrect time zone selected; temporary signal loss. | Verify the time zone setting (Section 6). Allow time for the clock to re-synchronize with the atomic signal. If persistent, try manual time setting (Section 7). |
| Display is dim or blank | Low or depleted batteries. | Replace batteries with fresh AA alkaline batteries (Section 8.1). |
| Temperature reading is inaccurate | Clock exposed to direct sunlight or heat source. | Move the clock to a location with stable ambient temperature. |
