Setup
8614C Digital Atomic Wall Clock Setup
- Powering the Digital Clock:
- Insert 3 AAA batteries (not included) into the battery compartment.
- For continuous backlight, plug the included power cord into the clock and a power outlet.
- Outdoor Sensor Setup:
- Insert 2 AAA batteries (not included) into the wireless outdoor sensor.
- Place the sensor outdoors within 200 feet (60 meters) of the digital clock in an open area. Ensure it is protected from direct sunlight and precipitation for accurate readings and longevity.
- The digital clock will automatically attempt to connect with the outdoor sensor. Once connected, the outdoor temperature will display.
- Atomic Time Synchronization:
- After powering on, the digital clock will automatically begin searching for the WWVB atomic signal. This process may take several minutes or up to 24 hours depending on location and signal strength.
- Ensure the clock is placed in an area with good reception, away from large metal objects or electronic interference.
- Once synchronized, the time will be set automatically.
- Placement: Use the integrated kickstand for desk placement or the hanging holes for wall mounting.

230012 Atomic Analog Wall Clock Setup
- Battery Installation: Insert 1 AA battery (included) into the battery compartment on the back of the clock.
- Atomic Time Synchronization:
- Upon battery insertion, the clock hands will automatically move to the 12 o'clock position and begin searching for the WWVB atomic signal.
- Place the clock in an area with optimal signal reception. Avoid placing it near large metal objects, electronic devices, or in basements.
- Synchronization can take several minutes to several hours. Once the signal is received, the clock will automatically set itself to the correct time for the selected time zone.
- Time Zone Selection: Refer to the small dial or buttons on the back of the clock to select your desired time zone (PST, MST, CST, EST).
- Daylight Saving Time (DST) Setting: Locate the DST switch on the back of the clock and set it to ON or OFF according to your region's DST observance.
- Mounting: Use the included wall hanging hook to securely mount the clock on a wall.

Operating Instructions
8614C Digital Atomic Wall Clock
- Display Information: The large LCD screen continuously displays time, date, day of the week, moon phase, indoor temperature, and outdoor temperature.
- Temperature Units: Press the "°C/°F" button (if available) to switch between Celsius and Fahrenheit for temperature readings.
- MIN/MAX Temperature: The clock automatically records and displays the daily minimum and maximum indoor and outdoor temperatures. Consult the full instruction manual for details on how to view or reset these values.
- Backlight Control: If using battery power only, the backlight may activate briefly when a button is pressed. If powered by the AC adapter, the backlight can be set to remain on, often with adjustable brightness levels. Refer to the specific buttons on the clock for backlight control.
- Alarm and Snooze: Set alarms and utilize the snooze function as per the detailed instructions in the included manual.
230012 Atomic Analog Wall Clock
- Automatic Time Adjustment: Once synchronized with the WWVB signal, the clock will automatically maintain accurate time and adjust for Daylight Saving Time (if enabled).
- Manual Time Setting (if needed): In rare cases where atomic signal is unavailable for an extended period, a manual set button may be present on the back. Consult the full instruction manual for manual time setting procedures.
Maintenance
- Cleaning: Wipe the clock surfaces with a soft, dry cloth. Avoid abrasive cleaners or solvents.
- Battery Replacement:
- For the 8614C Digital Clock: Replace AAA batteries when the low battery indicator appears on the display.
- For the 230012 Analog Clock: Replace the AA battery annually or when the clock stops keeping accurate time.
- For the Wireless Outdoor Sensor: Replace AAA batteries when the low battery indicator appears on the digital clock's display.
- Environmental Conditions: Ensure the outdoor sensor is placed in a location protected from extreme weather conditions to prolong its lifespan. The waterproof dustproof cover for the analog clock is for indoor use only.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Clock not synchronizing with atomic signal. | Weak signal due to location, interference from electronics, or distance from WWVB transmitter. |
|
| Incorrect time displayed. | Failed atomic synchronization, incorrect time zone setting, or DST setting. |
|
| Outdoor temperature not displayed or inaccurate. | Outdoor sensor out of range, low sensor batteries, or interference. |
|
| Digital clock backlight not staying on. | Clock is running on battery power only. |
