Setup
1. Unpacking
- Carefully remove the clock from its packaging.
- Inspect the clock for any signs of damage. If damage is present, contact customer support.
- Retain packaging materials for future transport or storage.
2. Battery Installation
The clock requires one (1) AA battery (not included).
- Locate the battery compartment on the back of the clock.
- Insert one fresh AA battery, ensuring the positive (+) and negative (-) terminals align correctly with the markings in the compartment.
- Close the battery compartment cover securely.
3. Initial Setup and Atomic Time Synchronization
Upon battery installation, the clock hands will typically perform a full sweep (12 hours) and then attempt to receive the atomic time signal from Fort Collins, Colorado, USA. This process ensures the clock sets itself to the precise time automatically.
- Placement: For optimal signal reception, place the clock near a window, ideally facing towards Colorado (generally west for most of the US). Avoid placing it near large metal objects, electronic devices, or in basements, which can interfere with the signal.
- Synchronization: The clock will attempt to synchronize every other hour. The initial synchronization may take several minutes to several hours depending on signal strength. During this time, the hands may move erratically before settling on the correct time.
- Daylight Saving Time (DST): The clock is designed to automatically adjust for Daylight Saving Time. Ensure any manual DST switch on the clock's movement is set to the appropriate position for your region (e.g., ON for regions observing DST, OFF otherwise).
- Time Zone: Some atomic clocks feature a time zone selector. If your model has one, set it to your local time zone (e.g., EST, CST, MST, PST). Refer to the markings on the back of the clock or the movement for specific controls.

Operating Instructions
Automatic Timekeeping
Once successfully synchronized, your Bulova Atomic Time 2 Analog Wall Clock will continuously maintain accurate time. It receives the atomic signal periodically to correct any minor deviations, ensuring precision.
Daylight Saving Time Adjustment
The clock automatically adjusts for Daylight Saving Time changes. No manual intervention is required for this transition, provided the DST switch (if present) is correctly set for your location.
Maintenance
Battery Replacement
Replace the AA battery approximately once a year, or when the clock hands stop moving or begin to lose time consistently. Always use a fresh, high-quality AA alkaline battery.
Cleaning
- To clean the clock case, use a soft, dry cloth. Avoid abrasive cleaners or solvents, which can damage the finish.
- For the glass lens, use a soft, lint-free cloth lightly dampened with a glass cleaner. Spray cleaner onto the cloth, not directly onto the clock, to prevent liquid from seeping into the movement.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Clock not setting time automatically or displaying incorrect time. | Weak or no atomic signal reception. Depleted battery. Incorrect DST or time zone setting. | Ensure the clock is placed in an area with good signal reception (e.g., near a window, away from electronics). Replace the battery with a fresh AA battery. Verify DST and time zone settings on the clock's movement. Perform a manual reset by removing and reinserting the battery. |
| Clock hands are not moving. | Depleted battery. Battery inserted incorrectly. Movement malfunction. | Replace the battery with a fresh AA battery, ensuring correct polarity. Check battery contacts for corrosion. If the issue persists, contact customer support. |
| Time is consistently off by an hour. | Incorrect Daylight Saving Time (DST) setting. | Check the DST switch on the back of the clock and adjust it to the correct setting for your region. |
| Difficulty reading the clock due to reflection. | Placement under direct light sources. | Reposition the clock to avoid direct overhead lighting or windows that cause glare on the convex glass lens. |
