4.3 Placing the Outdoor Sensor
For optimal performance, place the outdoor sensor in a shaded location, away from direct sunlight and precipitation. Ensure it is within 200 feet (60 meters) of the main clock unit and has a clear line of sight for wireless transmission.
4.4 Sensor Protection Shield Installation
The Sensor Protection Shield (Model 925-1418) is designed to protect your outdoor sensor from environmental elements.
- Open the shield by separating its two halves.
- Place your outdoor sensor inside the shield. Ensure the sensor's ventilation openings are not obstructed.
- Close the shield securely.
- Mount the shield using the provided hardware on a wall post or flat surface. The shield's design allows for optimal air ventilation while protecting the sensor.

4.5 Atomic Time Synchronization
Upon initial power-up, the clock will automatically attempt to synchronize with the WWVB atomic time signal. This process may take several minutes to several hours depending on your location and signal strength. A tower icon on the display indicates signal reception.
4.6 Manual Time and Date Setting
If atomic time synchronization is not desired or unavailable, you can manually set the time and date:
- Press and hold the 'CALENDAR' button to enter manual setting mode.
- Use the '+' or '-' buttons to adjust values.
- Press 'CALENDAR' again to confirm each setting and move to the next (Year, Month, Date, Hour, Minute, 12/24 Hour format, Daylight Saving Time ON/OFF).
5. Operating Instructions
5.1 Display Modes

- Ensure the outdoor sensor and its protection shield are free from debris and obstructions for accurate readings.
7. Troubleshooting
| Problem | Solution |
|---|---|
| No display on clock. | Ensure AC adapter is securely plugged in. Check wall outlet. Verify backup batteries are correctly installed. |
| Outdoor temperature not displayed. | Ensure outdoor sensor batteries are fresh and correctly installed. Relocate sensor closer to the clock. Press the 'SENSOR' button on the clock to manually search for the sensor. |
| Atomic time not syncing. | Place the clock near a window, away from electronics that may cause interference. Allow up to 24 hours for synchronization. Manually set time if necessary. |
| Projection is blurry or unclear. | Adjust the focus wheel on the projection lens. Ensure the projection surface is within the optimal range. |
| Projection is upside down or sideways. | Rotate the projection arm 180 degrees or adjust the projection orientation button (if available) to correct the display. |
