3.2 Initial Synchronization and Time Zone Selection
Upon battery insertion, the clock will automatically begin searching for the NIST atomic time signal. This process may take several minutes to several hours, depending on your location and signal strength. The atomic time signal is broadcast from Colorado, USA, and is primarily effective in North America.
- Sebaka sa Nako: Locate the time zone switch or button on the back of the clock. Select your appropriate North American time zone: Pacific, Mountain, Central, Eastern, Atlantic, Newfoundland, Alaska, or Hawaii.
- Kamohelo ea Letšoao: For optimal signal reception, place the clock near a window, away from electronic devices that may cause interference. The signal is often strongest during nighttime hours.
