Setup
- Battery Installation:
- Open the battery compartment on the back of the main clock unit.
- Insert the required batteries, observing the correct polarity (+/-).
- Close the battery compartment.
- Repeat this process for the wireless outdoor sensor.
- Initial Power-Up:
Once batteries are inserted, the clock will power on and begin searching for the Radio Controlled (RC) signal (WWVB in North America). This process may take several minutes or up to 24 hours depending on signal strength and location. Place the clock near a window for better reception.
- Outdoor Sensor Pairing:
The main unit will automatically attempt to connect with the outdoor sensor. Ensure the sensor is placed within range (typically up to 30 meters/100 feet in open air) and away from major metallic objects or electronic interference. If pairing does not occur automatically, refer to the troubleshooting section.
- Placement:
Position the main clock unit indoors on a flat surface. Place the outdoor sensor in a shaded, dry location outdoors, protected from direct sunlight and rain, to ensure accurate temperature readings.
Operating Instructions
Time and Date Settings
- Radio Controlled Time (WWVB): The clock automatically synchronizes with the WWVB signal for accurate time. The signal icon will indicate successful reception.
- Manual Time Setting: If the RC signal is unavailable, press and hold the 'TIME SET' button (often marked with a clock icon) to enter manual time setting mode. Use the '+' and '-' buttons to adjust hours, minutes, year, month, and day. Press 'TIME SET' again to confirm each setting.
- 12/24 Hour Format: Press the '+' button during normal time display to switch between 12-hour (with AM/PM indicator) and 24-hour formats.
- Weekday Language: Press and hold the 'LANGUAGE' button (if available, or often combined with other settings) to cycle through English (EN), German (GE), French (FR), Italian (IT), and Dutch (DU).
Alarm Settings
- Setting Alarms: Press the 'ALARM' button (often marked with a bell icon) to view Alarm 1. Press and hold 'ALARM' to enter Alarm 1 setting mode. Use '+' and '-' to adjust the alarm time. Press 'ALARM' to confirm. Repeat for Alarm 2.
- Activating/Deactivating Alarms: Press 'ALARM' repeatedly to toggle Alarm 1 ON/OFF, then Alarm 2 ON/OFF. An alarm icon will appear on the display when active.
- Snooze Function: When an alarm sounds, press the 'SNOOZE' button (located on top) to temporarily silence the alarm for a few minutes. The alarm will sound again after the snooze period.
Weather and Temperature Display
- Temperature Units: Press the '°C/°F' button (often combined with '+' or '-') to switch between Celsius and Fahrenheit display for both indoor and outdoor temperatures.
- Weather Forecast: The clock displays a weather forecast icon (e.g., sunny, cloudy, rainy) based on changes in atmospheric pressure. This is a prediction and may not always match current conditions precisely.
- Multiple Outdoor Sensors: If you have additional compatible sensors (up to 3 supported), press the 'CHANNEL' button (often combined with '+') to cycle through the outdoor sensor readings.
Projection Feature
- Activating Projection: Press the 'PROJECTION' button (or a dedicated button near the projector lens) to turn the time projection ON/OFF.
- 180° Flip: The projection arm can be rotated 180 degrees to adjust the projection angle. The projected time can also be flipped 180 degrees digitally by pressing the projection button repeatedly to ensure correct orientation on the wall or ceiling.
- Focus Adjustment: Rotate the focus ring on the projector lens to sharpen the projected image.
Backlight
- Press the 'LIGHT' or 'SNOOZE' button to activate the display backlight for a few seconds.
Maintenance
- Cleaning: Wipe the clock and sensor with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Battery Replacement: Replace batteries in both the main unit and outdoor sensor when the low battery indicator appears on the display. Use fresh batteries of the specified type.
- Storage: If storing the device for an extended period, remove all batteries to prevent leakage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display or dim display | Low or dead batteries; incorrect battery polarity. | Replace batteries with new ones, ensuring correct polarity. |
| No RC time signal (WWVB) | Interference; poor reception area; signal not yet received. | Move the clock closer to a window; avoid electronic devices; allow up to 24 hours for signal acquisition. Manually set time if necessary. |
| Outdoor temperature not displayed or incorrect | Sensor out of range; sensor batteries low; interference; sensor not paired. | Ensure sensor is within range; replace sensor batteries; re-pair sensor (refer to setup); avoid placing sensor in direct sunlight. |
| Projection is blurry | Focus not adjusted. | Rotate the focus ring on the projector lens until the image is clear. |
