Setup
1. Battery Installation
The clock is powered by 2 AAA alkaline batteries (not included). To install:
- Gently slide off the battery compartment cover located on the back of the clock.
- Insert two AAA batteries, ensuring correct polarity (+ and -).
- Replace the battery compartment cover.
2. Initial Setup and Atomic Time Synchronization
Upon battery installation, the clock will automatically attempt to synchronize with the WWVB atomic time signal. This process may take several minutes to overnight, depending on your location and signal strength. It is recommended to place the clock near a window or in an open area for better reception.

3. Setting Time Zone and DST
After initial power-on or if atomic synchronization is not desired, you can manually set the time zone and Daylight Saving Time (DST) status.

- Press the "TIME ZONE" button (often labeled "UP/TIME ZONE") to cycle through the available time zones (e.g., AST, EST, CST, MST, PST, AKST, HAT). Select your local time zone.
- To enable or disable DST, locate the DST setting (often combined with the atomic signal button or a separate switch) and adjust as needed.
- To manually set time and alarm, press the "SET" button and use the UP/DOWN buttons to adjust values. Press SET again to confirm each setting.
