4.2 Initial Power-Up and Atomic Signal Reception
Upon battery installation, the clock will automatically power on and begin searching for the WWVB atomic time signal. This process may take several minutes to several hours, depending on your location and environmental conditions. During this time, the signal reception indicator (often a wave icon) will flash.
- For optimal signal reception, place the clock near a window, away from electronic devices that may cause interference.
- The clock is designed to receive signals primarily in North America. Signal strength may vary in other regions.
- Once the signal is successfully received, the time and date will automatically set, and the signal indicator will become solid.

5. Instrucciones de funcionamiento
The clock's display provides the following information:
- Tiempo: Large digits indicate the current time (12-hour format with AM/PM indicator).
- Fecha: Mes y día.
- Día de la semana: Abbreviated day name.
- Temperatura: Temperatura interior en Celsius o Fahrenheit.
- Indicador de señal atómica: Shows the status of atomic signal reception.
5.1 Funciones de los botones
The clock typically has buttons on the back for various settings. Common buttons include:
- CONJUNTO: Enters or confirms setting modes.
- MODO: Toggles between display modes or setting options.
- WAVE / RCC: Manually initiates atomic signal search.
- ZONA HORARIA: Selects the desired time zone.
- +/C/F: Adjusts values during setting or switches temperature unit (Celsius/Fahrenheit).
6. Configuración de zona horaria
To set your local time zone:
- Presione el ZONA HORARIA button. The current time zone will begin to flash.
- Presione el + or - button (if available, or MODO/COLOCAR) to cycle through the available time zones (e.g., PST, MST, CST, EST, AST, NST, HST, AKST).
- Once your desired time zone is displayed, press the COLOCAR button to confirm. The clock will then adjust to the correct time for that zone after receiving the atomic signal.
7. Ajuste manual de la hora
If the atomic signal is consistently unavailable or if you prefer to set the time manually:
- Mantenga pulsado el COLOCAR button for approximately 3-5 seconds until the hour digits begin to flash.
- Utilice el + or - botón para ajustar la hora.
- Prensa COLOCAR again to move to the minute digits, then adjust with + or -.
- Continuar presionando COLOCAR para recorrer las configuraciones de año, mes y día, ajustando cada una con + or -.
- Después de configurar todos los parámetros deseados, presione COLOCAR one last time to exit the manual setting mode.
Nota: If the atomic signal is enabled, the clock may attempt to override manual settings once a strong signal is received. To prevent this, you may need to disable the atomic synchronization feature if available (refer to specific button functions on your clock).
8. Mantenimiento
8.1 Reemplazo de batería
When the display dims or the clock stops functioning, it is time to replace the batteries. Follow the battery installation steps in Section 4.1. Always use fresh AA alkaline batteries.
