Initial Setup
Powering the Clock
The Geevon Atomic Alarm Clock can be powered by the included AC adapter or by batteries for backup.
- AC Power: Connect the AC power adapter to the clock and plug it into a standard electrical outlet. The display will light up.
- Battery Backup: For continuous operation during power interruptions and to retain settings, install 3 AAA batteries (not included) into the battery compartment on the back of the clock. A low-battery warning function will appear on the display when replacement is needed.
Figure 3: AC Power and Battery Backup. Ensure batteries are installed for uninterrupted operation and setting retention during power outages.
Automatic Time Synchronization (WWVB)
The clock is equipped with a WWVB function that automatically synchronizes the time with the atomic clock signal. This ensures precise timekeeping and automatic adjustment for Daylight Saving Time (DST).
- Upon initial power-up, the clock will attempt to receive the WWVB signal. This process may take several minutes or hours depending on your location and signal strength.
- Ensure the correct time zone is selected for proper atomic synchronization.
- To manually initiate signal reception, press and hold the ATOMIC button. The backlight will temporarily turn off during reception.

Troubleshooting
If you encounter any issues with your Geevon Atomic Alarm Clock, please refer to the common troubleshooting tips below. For a comprehensive guide, please consult the official Troubleshooting Guide PDF.
- No Display/Dim Display: Ensure the AC adapter is securely plugged in. If using battery backup, check if batteries are correctly inserted and have sufficient charge. The adjustable backlight requires AC power.
- Incorrect Time: Verify that the correct time zone is selected. If using atomic synchronization, ensure the clock is in an area with good signal reception and allow time for synchronization. Manually set the time if automatic synchronization is not working.
- Alarm Not Sounding: Check if the alarm is activated (bell icon visible on display). Ensure the alarm time is set correctly.
- Temperature/Humidity Readings Inaccurate: Ensure the clock is placed in a stable indoor environment, away from direct sunlight, heat sources, or drafts that could affect readings.
