5. Instrucciones de funcionamiento
5.1 Visualización sobreview
The receiver's LCD displays the following information:

Image: The receiver's digital display, highlighting the current temperature readings for two channels, along with their respective maximum and minimum recorded temperatures and low battery indicators.
- Channel 1 Temperature: Typically for the refrigerator.
- Channel 2 Temperature: Typically for the freezer.
- Registros máximos/mínimos: Highest and lowest temperatures recorded since the last reset.
- Indicador de batería baja: Appears when receiver or transmitter batteries are low.
- Indicador de intensidad de la señal: Shows connection status to transmitters.
5.2 Selección de la unidad de temperatura (°F/°C)
Para cambiar entre Fahrenheit (°F) y Celsius (°C), presione el botón LIGHT °F/°C button on the receiver unit.
5.3 Configuración de alertas de temperatura
The system allows you to set custom high and low temperature limits for each channel. An audible and visual alarm will activate if the temperature exceeds these limits.

- Presione el MODO button once to enter the alarm setting mode for Channel 1 (refrigerator). The high limit will flash.
- Utilice el UP or ABAJO buttons to adjust the desired high temperature limit.
- Prensa MODO again to set the low limit for Channel 1. Adjust with UP or ABAJO.
- Prensa MODO a third time to enter the alarm setting mode for Channel 2 (freezer). Repeat steps 2 and 3 for Channel 2.
- Prensa MODO again to exit alarm setting mode. The alarm icon will appear next to the channel if an alarm is active.
5.4 Viewing and Clearing Max/Min Records
The receiver automatically records the maximum and minimum temperatures for each channel since the last reset.
- Presione el HISTORY/CLEAR botón una vez para view the maximum recorded temperatures for both channels.
- Prensa HISTORY/CLEAR De nuevo a view the minimum recorded temperatures for both channels.
- Para borrar los registros Máx./Mín., mantenga presionada la tecla HISTORY/CLEAR botón durante 3 segundos mientras viewing the records. The display will reset to current temperatures.
5.5 Pautas de colocación
La ubicación óptima garantiza lecturas precisas y una comunicación inalámbrica confiable.
