Setup Guide
1. Battery Installation
- Locate the battery compartments on the back of the clock.

Note: Batteries are not included with the product. Use fresh alkaline batteries for optimal performance.
2. Initial Time Synchronization (Atomic Signal)
After battery installation, the clock will automatically attempt to receive the WWVB atomic time signal from Fort Collins, Colorado. This process may take several minutes to several hours, depending on your location and environmental conditions.
- The clock hands will typically move to the 12:00 position and then begin searching for the signal.
- Once the signal is received, the clock will automatically set itself to the correct time for the selected time zone.

3. Setting Time Zone and DST
On the back of the clock, locate the time zone selection switch and the DST (Daylight Saving Time) switch.
- Time Zone: Select your desired time zone (PST, MST, CST, EST) using the switch.
- DST: Set the DST switch to "ON" for automatic Daylight Saving Time adjustments, or "OFF" if your region does not observe DST.
4. Adjusting Night Light Brightness
The smart night light has three brightness levels. On the back of the clock, locate the brightness adjustment button.
- Press the button to cycle through the settings: Off, Low Brightness, High Brightness.
- Select the desired brightness level for the night light feature.

Operating Instructions
Automatic Timekeeping
Once set up, the WallarGe Atomic Wall Clock will automatically receive the WWVB signal daily, typically overnight, to ensure accurate timekeeping. No manual adjustments are required under normal operation.
Smart Night Light Function
The integrated light sensor detects ambient light levels. When the room darkens, the night light will automatically activate at the previously selected brightness level (Low or High). When the room brightens, the night light will turn off to conserve battery power.
Silent Operation
The clock features an upgraded precise quartz movement that ensures a completely silent, non-ticking operation. This makes it suitable for environments where quiet is preferred, such as bedrooms, offices, and classrooms.

Maintenance
Battery Replacement
When the clock hands stop moving or the night light dims significantly, it is time to replace the batteries. Follow the battery installation steps in the Setup Guide. Always replace all batteries at once with new ones of the same type.
Cleaning
To clean the clock, gently wipe the surface with a soft, dry cloth. Do not use abrasive cleaners, solvents, or chemical sprays, as these may damage the clock's finish or internal components.
Environmental Considerations
Avoid placing the clock in direct sunlight, near strong magnetic fields, or in areas with extreme temperatures or high humidity, as these conditions can affect accuracy and lifespan.
