Setup
Follow these steps for initial setup of your atomic wall clock:
- Install Battery: Open the battery compartment cover on the back of the clock. Insert one fresh AA battery, ensuring the correct polarity (+ and -).
- Select Time Zone: Before the clock attempts to set itself, locate the time zone switch on the back of the clock (refer to Figure 2). Set it to your desired time zone:
- PST: Pacific Standard Time
- MST: Mountain Standard Time
- CST: Central Standard Time
- EST: Eastern Standard Time
- Initial Synchronization: Once the battery is installed and the time zone is set, the clock hands will automatically move to the 12:00 position. The clock will then begin searching for the atomic time signal from Fort Collins, Colorado. This process can take anywhere from a few minutes to several hours, especially if the signal is weak or during daytime. For best reception, place the clock near a window, facing towards Colorado if possible.
- Automatic Time Setting: Once the signal is received, the clock will automatically set itself to the correct time for your selected time zone, including adjusting for Daylight Saving Time (DST) automatically.
- Manual Time Setting (Optional): If the clock does not set itself automatically after 24 hours, or if you are outside the reception range, you can manually set the time using the buttons on the back of the clock. Refer to the "Troubleshooting" section for more details on manual setting.
- Mounting: The clock features a keyhole slot on the back for easy wall mounting. Ensure you use a sturdy screw or hook capable of supporting the clock's weight.
Operating
The Adalene Atomic Wall Clock is designed for minimal user intervention once set up.
- Automatic Time Adjustment: The clock continuously monitors the atomic time signal. It will automatically adjust for Daylight Saving Time changes and maintain accurate time without manual intervention.
- Battery Life: A single AA battery typically powers the clock for approximately one year. Replace the battery annually or when the clock hands stop moving or become erratic.
Maintenance
Proper care will ensure the longevity and performance of your clock.
- Cleaning: Wipe the clock's surface and glass cover with a soft, dry cloth. Do not use abrasive cleaners or chemical solvents, as they may damage the finish.
- Battery Replacement: When replacing the battery, always use a fresh, high-quality AA alkaline battery. Remove old batteries promptly to prevent leakage.
- Storage: If storing the clock for an extended period, remove the battery to prevent potential damage from battery leakage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Clock does not set automatically. | Weak atomic signal, incorrect time zone setting, low battery. |
|
| Clock hands are stuck or not moving. | Dead or low battery, hands are obstructed. |
|
| Clock is displaying the wrong time. | Incorrect time zone, failed synchronization, DST issue. |
|
Manual Time Setting:
If automatic synchronization fails, you can manually set the time:
- Ensure a fresh AA battery is installed.
- Locate the manual set buttons on the back of the clock (often labeled "SET" or with arrows).
- Press and hold the appropriate button to advance the hands until the correct time is displayed. Some models may have separate buttons for hour and minute adjustment.
- Once the time is set, the clock will continue to operate as a standard quartz clock. It may still attempt to receive the atomic signal periodically.
