2. Initial Synchronization and Time Zone Selection
Upon battery installation, the clock will automatically begin searching for the WWVB atomic time signal. This process may take several minutes to a few hours depending on signal strength. The clock's default time zone is Eastern Time (EST).
- Time Zone: To change the time zone, locate the "TIME ZONE" button on the back of the clock. Press it repeatedly to cycle through the available time zones (PST, MST, CST, EST) until your desired zone is displayed.
- Signal Reception: For optimal signal reception, place the clock in an open area or near a window, away from large metal objects or concrete structures.

Operating Instructions
1. Automatic Time Synchronization (Atomic Clock Feature)
The WallarGe Atomic Clock automatically synchronizes with the WWVB radio broadcast from Fort Collins, Colorado, ensuring accuracy within one second for thousands of years. The clock attempts to receive the signal daily at midnight and adjusts the time setting as needed. This feature eliminates the need for manual time adjustments, including for Daylight Saving Time (DST).

2. Manual Time Setting
If the atomic time signal cannot be received successfully, or if you prefer manual control, you can set the time, date, and other parameters manually.
- Time/Date Set: Press and hold the "TIME SET" button on the back of the clock for 2 seconds to enter manual setting mode. Use the "UP" and "DOWN" buttons to adjust values, and "TIME SET" to confirm and move to the next setting (Year, Month, Date, Hour, Minute).
- 12/24 Hour Format: While in manual setting mode, use the "UP" button to toggle between 12-hour and 24-hour time formats.
- Celsius/Fahrenheit: Use the "UP °C/°F" button to switch between Celsius and Fahrenheit temperature units.
3. Temperature Monitoring
The clock displays both indoor and outdoor temperatures. The indoor temperature is measured by a built-in sensor, while the outdoor temperature is transmitted wirelessly from the external sensor.
- Indoor Temperature: The indoor temperature is displayed on the main screen and updates every 10 seconds.
- Outdoor Temperature: The outdoor sensor transmits data every 32 seconds. Ensure the sensor is placed within 330 feet (100m) of the clock for reliable transmission.

4. Alarm Function
The clock includes an alarm feature to help you keep track of important events.
- Setting Alarm: Press and hold the "ALARM SET" button on the back of the clock for 2 seconds. Use the "UP" and "DOWN" buttons to set the desired alarm time. Press "ALARM SET" again to confirm.
- Activating/Deactivating Alarm: Press the "AL ON/OFF" button to toggle the alarm on or off. An alarm icon will appear on the display when active.
- Snooze Function: When the alarm sounds, press the large snooze button on top of the clock to temporarily silence it. The alarm will sound again after a few minutes.
Maintenance
1. Battery Replacement
Replace batteries in both the clock and the outdoor sensor when the low battery indicator appears on the display. It is recommended to replace all batteries at the same time to ensure consistent performance. Use high-quality, non-rechargeable AA batteries.
2. Cleaning
Wipe the clock and sensor with a soft, dry cloth. Do not use abrasive cleaners or chemicals, as these may damage the display or casing.
3. Outdoor Sensor Placement
For accurate outdoor temperature readings, place the sensor in a shaded area, away from direct sunlight and heat sources. Ensure it is protected from direct rain and snow. The maximum receiving distance is 330 feet (100m). Avoid placing the sensor near large metal objects or thick concrete walls that could interfere with the wireless signal.
