This manual provides detailed instructions for the setup, operation, and maintenance of your Geevon Digital Atomic Wall Clock with Moon Phase and Backlight (Model GN-228614C-T3-US). Please read this manual thoroughly before using the product to ensure proper function and longevity.
2. What's Included
Upon unpacking, verify that all components are present:
- One atomic clock
- One outdoor sensor
- One AC/DC power adapter
- One user manual
Note: 3 AAA batteries for the main unit and 2 AAA batteries for the outdoor sensor are required but not included.
3. Setup
3.1. Powering the Main Unit
The main unit can be powered by either the included AC/DC power adapter or 3 AAA batteries (not included).
- Using AC Power: Connect the AC/DC power adapter to the clock's power input port and plug it into a standard electrical outlet.
- Using Batteries: Open the battery compartment on the back of the clock and insert 3 new AAA batteries, observing the correct polarity (+/-).

3.2. Installing the Outdoor Sensor
The wireless outdoor sensor requires 2 AAA batteries (not included).
- Open the battery compartment on the back of the outdoor sensor.
- Insert 2 new AAA batteries, observing the correct polarity (+/-).
- Close the battery compartment.
- Place the sensor in a covered outdoor location, such as under a patio or porch, to protect it from direct sunlight and rain. Ensure it is within 200 feet (60 meters) of the main unit.

3.3. Initial Synchronization and Time Zone Setting
The clock automatically attempts to synchronize with the WWVB atomic clock signal from Fort Collins, Colorado. This process can take 2-5 days for initial synchronization, especially if the signal is weak. During signal reception, the backlight will temporarily turn off for 1-2 minutes to avoid interference.
To manually set the time zone and other settings:
- Press and hold the "MODE" button for 3 seconds. The hour display will start to flash. Use the "UP" or "DOWN" buttons to set the correct hour.
- Press "MODE" to confirm and move to the minute setting. Use "UP" or "DOWN" to set the correct minute.
- Continue pressing "MODE" to cycle through year, month, and date settings, adjusting each with "UP" or "DOWN".
- After setting the date, the Daylight Saving Time (DST) display will flash. Use "UP" or "DOWN" to turn DST on or off as applicable.
- Next, the Time Zone display will flash. Use "UP" or "DOWN" to select your time zone (EST, AST, HST, AKST, PST, MST, CST).
- Finally, the temperature unit (°C/°F) will flash. Use "UP" or "DOWN" to select your preferred unit.
- Press "MODE" again to confirm all settings and end the setting procedures, entering the normal mode.

4. Operating Instructions
4.1. Display Overview
The 8.8-inch LCD TN HD display shows the following information:
- Time (12/24H format)
- Date and Day of the Week
- Moon Phases
- Indoor Temperature (°C/°F)
- Outdoor Temperature (°C/°F)
- Daily Minimum and Maximum Temperature Data
- Temperature Trends (rising/falling)

4.2. Backlight Control
The clock features 3 brightness levels: Off, Dim, and Bright. The backlight behavior depends on the power source:
- AC Power: The backlight can remain on continuously at your chosen brightness level.
- Battery Power: To conserve battery life, the backlight will illuminate for 10 seconds when the top button is tapped, then turn off.
Image: The clock display shown with three different backlight settings: High, Low, and Off, demonstrating the adjustable brightness feature.
Video: This video demonstrates the three backlight brightness levels (Off, Dim, Bright) of the Geevon Atomic Wall Clock and how to adjust them by touching the top button. It also shows the clock in various room settings.
4.3. Alarm and Snooze Function
The clock includes an alarm with a snooze feature:
- Setting Alarm: Press the "ALARM" button on the back of the clock to enter alarm setting mode. Use "UP" or "DOWN" to set the desired alarm time. Press "ALARM" again to confirm.
- Activating Alarm: Once set, the alarm will sound with a gradually increasing "beep" sound.
- Snooze: Press the "SNZ" button (top button) during the alarm to activate the 5-minute snooze function.
- Stopping Alarm: To stop the alarm completely, press any other button besides "SNZ". If no action is taken, the alarm will automatically stop after 2 minutes.

4.4. Temperature Unit Switching
To switch between Celsius (°C) and Fahrenheit (°F) for temperature display, press the "UP/RCC" button on the back of the clock during normal operation.
4.5. Max/Min Temperature Records
The clock records the daily minimum and maximum indoor and outdoor temperatures. Press the "MEM" button on the back of the clock to view these records. Press it again to cycle through current, maximum, and minimum readings.
5. Placement Options
The Geevon Digital Atomic Wall Clock offers versatile placement options:
- Tabletop Use: Utilize the integrated tripod stand on the back for stable placement on a desk, nightstand, or shelf.
- Wall Mounting: Use the two hanging holes on the back to mount the clock securely on a wall.
Image: The clock is shown with its foldable stand for tabletop use and also with hanging holes for wall mounting, illustrating its two placement methods.
For optimal performance, place both the main unit and the outdoor sensor at least 3 feet (1 meter) away from electronic devices such as TVs, computers, microwaves, or radios, as these can cause electromagnetic interference.
6. Maintenance
- Cleaning: Wipe the clock and sensor with a soft, dry 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. Always replace all batteries at the same time with new ones.
- Storage: If storing the unit for an extended period, remove all batteries to prevent leakage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on main unit. | No power or dead batteries. | Ensure AC adapter is properly connected or replace batteries. |
| Outdoor temperature not displayed or inaccurate. | Outdoor sensor batteries dead, out of range, or interference. | Replace sensor batteries. Move sensor closer to the main unit. Ensure no large metal objects or electronics are between units. |
| Atomic time not synchronizing. | Weak WWVB signal, interference, or incorrect time zone. | Ensure correct time zone is set. Move clock to a location with better signal reception (e.g., near a window, away from electronics). Allow 2-5 days for initial synchronization. Signal reception is usually better at night. |
| Backlight not staying on (when using AC power). | Power adapter not connected or faulty. | Ensure AC adapter is securely plugged in. If problem persists, contact support. |
