Operating Instructions

1. Atomic Time Synchronization

This clock is designed to automatically synchronize with the official U.S. time standard via the NIST's Colorado atomic signal tower. Upon initial power-up or after battery replacement, the clock will attempt to receive the atomic signal. This process may take several minutes or hours depending on your location and signal strength. Ensure the clock is placed in an area with good reception, away from large metal objects or electronic interference.
