Setup
1. Battery Installation
- Open the battery compartment cover on the back of the unit.
- Insert two (2) AAA batteries, observing the correct polarity (+ and -).
- Close the battery compartment cover. These batteries provide backup power during outages.
2. Connect AC Power Adapter
- Plug the AC power adapter into the DC IN jack on the back of the clock.
- Plug the adapter into a standard wall outlet. The clock will power on, and the LCD display will activate. Continuous projection requires AC power.
3. Atomic Clock Synchronization
Upon initial power-up, the clock will automatically attempt to synchronize with the atomic clock signal. This process may take several minutes to several hours, depending on your location and signal strength. Place the clock near a window for best reception.
- A signal icon will appear on the LCD when synchronization is successful.
- To manually initiate a signal search, press and hold the UP button for 3 seconds.
4. Setting Time Zone
After successful atomic synchronization, you may need to set your local time zone.
- Press and hold the MODE button for 3 seconds to enter time setting mode.
- Press the MODE button repeatedly until the Time Zone setting flashes.
- Use the UP or DOWN buttons to select your desired time zone (e.g., EST, CST, MST, PST).
- Press MODE to confirm and exit, or wait 30 seconds for automatic exit.
Operating Instructions
Manual Time and Date Setting (If Atomic Sync Fails)
- Press and hold the MODE button for 3 seconds. The hour digit will flash.
- Use the UP or DOWN buttons to adjust the hour.
- Press MODE to confirm and move to the next setting (minutes, year, month, day, 12/24 hour format, Daylight Saving Time (DST) ON/OFF).
- Repeat steps 2 and 3 until all settings are adjusted.
- Press MODE to exit, or wait 30 seconds for automatic exit.
Setting Alarms (Alarm 1 and Alarm 2)
The clock features two independent alarms (Alarm 1 and Alarm 2).
- Press the ALARM 1 or ALARM 2 button once to display the current alarm time.
- Press and hold the respective ALARM button for 3 seconds. The alarm hour will flash.
- Use the UP or DOWN buttons to adjust the alarm hour.
- Press the ALARM button to confirm and move to alarm minutes.
- Adjust alarm minutes using UP or DOWN.
- Press the ALARM button to confirm and move to alarm type (Daily or Weekday).
- Adjust alarm type using UP or DOWN.
- Press the ALARM button to confirm and exit, or wait 30 seconds for automatic exit.
To activate or deactivate an alarm, press the ALARM 1 or ALARM 2 button once. An alarm icon will appear on the LCD when active.
Snooze Function
When an alarm sounds, press the SNOOZE/LIGHT button to temporarily silence the alarm for approximately 8 minutes. The alarm will sound again after the snooze period. To stop the alarm completely, press any other button.
Time Projection
- Continuous Projection: Slide the PROJECTION ON/OFF switch to ON. The time will be continuously projected. This feature requires the AC power adapter to be connected.
- Temporary Projection: If continuous projection is off, press the SNOOZE/LIGHT button to activate projection for approximately 15 seconds.
- Projection Orientation: Press the PROJECTION ROTATION button to flip the image 180 degrees, ensuring it is displayed right-side up on your chosen surface.
- Adjusting Projection Angle: The projection lens can be manually tilted to adjust the projection angle on your ceiling or wall.
LED Backlight
Press the SNOOZE/LIGHT button to illuminate the LCD display backlight for approximately 15 seconds.
Maintenance
Cleaning the Unit
Wipe the clock with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these may damage the unit. Ensure the unit is unplugged from the AC power before cleaning.
Battery Replacement
When the backup batteries are low, the display may dim or settings may be lost during power outages. Replace the two (2) AAA batteries in the battery compartment, observing correct polarity.
Troubleshooting
| Problem | Solution |
|---|---|
| Clock display is blank or dim. | Ensure the AC power adapter is securely connected to both the clock and a working wall outlet. Check if backup batteries are installed correctly and are not depleted. |
| Atomic time synchronization fails or is inaccurate. | Place the clock near a window, away from electronic devices that may cause interference. Manually initiate a signal search by holding the UP button. If synchronization consistently fails, manually set the time and date. |
| Time projection is not visible or is dim. | Ensure the AC power adapter is connected for continuous projection. Check the PROJECTION ON/OFF switch. Adjust the projection lens angle. Ensure the room is sufficiently dark for optimal visibility. |
| Projected time is upside down or backwards. | Press the PROJECTION ROTATION button to flip the image 180 degrees. Adjust the physical orientation of the clock if needed. |
| Alarm does not sound. | Ensure the alarm is activated (alarm icon visible on LCD). Verify the alarm time is set correctly. Check if the volume is not set to minimum (if applicable, though this model doesn't specify volume control). |
| Snooze/Light button only activates backlight for 15 seconds, not 5 minutes. | The backlight duration is fixed at approximately 15 seconds for temporary illumination. The 5-minute duration mentioned in some older documentation may not apply to this specific model. |
