4.2 Col·locació del sensor exterior

For accurate temperature and humidity readings, place the outdoor sensor in a location that is:

• Out of direct sunlight and rain.
• Away from any heat sources (e.g., vents, exhaust fans) or extreme cold sources.
• Within the wireless transmission range of 328 feet (100 meters) from the main clock unit.

4.3 Initial Atomic Time Synchronization

After battery installation, the clock will automatically attempt to synchronize with the WWVB atomic time signal. This process may take several minutes to several hours, depending on your location and signal strength. Ensure the clock is placed in an area where it can receive a clear signal, ideally near a window and away from electronic interference.

5. Instruccions de funcionament

5.1 Manual Time and Date Setting

While the clock primarily relies on atomic synchronization, you can manually set the time and date if needed (e.g., during initial setup before signal acquisition or in areas with poor reception).

1. Manteniu premut el botó SET button on the back of the clock until the display flashes.
2. Utilitza el UP or DOWN/RCC botons per ajustar el valor intermitent (per exemple, hora, minut, any, mes, dia).

4. Repetiu fins que tots els paràmetres desitjats estiguin configurats.

5.2 Time Zone Selection

The clock supports 8 time zones. After atomic synchronization, you may need to select your local time zone.

• Premeu el botó SET button repeatedly until the time zone setting flashes.
• Utilitza el UP or DOWN/RCC buttons to cycle through the available time zones (EST, CST, MST, PST, AKT, HST, AST, NST).
• Premeu SET per confirmar la vostra selecció.

5.3 Selecció de la unitat de temperatura (°C/°F)

To switch between Celsius and Fahrenheit for temperature display:

• Premeu breument DOWN/RCC button. The temperature unit will toggle between °C and °F.

5.4 Funció de despertador

The clock includes an alarm function.

1. Premeu el botó ALARMA botó per view l'hora actual de l'alarma.
2. Manteniu premut el botó ALARMA botó fins que l'hora de l'alarma parpellegi.
