![$VVLJQPHQWV9+)0DULQH&KDQQHO$VVLJQPHQWVNOTE Many of the plain-numbered channels, such as 01, 02 and 03, transmit and receive on different frequencies. This is termed duplex operation. The rest of the plain-numbered channels and all of the A channels, such as 01A, 03A and 04A, transmit and receive on a single frequency, which is termed simplex operation. Your radio automatically adjusts to these conditions. When in simplex operation, the A icon will appear on the LCD (see illustration on page A3).NOTE All channels are preprogrammed at the factory according to international regulations and those of the FCC (U.S.A.) and Industry Canada (Canada). They cannot be altered by the user nor can modes of operation be changed between simplex and duplex. NOTA Muchos de los canales de números simples, como 01, 02 y 03, transmiten y reciben en diferentes frecuencias. A esto se le llama operación dúplex. El resto de los canales de números simples y todos los canales A, como 01A, 03A y 04A, transmiten y reciben en una sola frecuencia, a la que se le llama operación simple (simplex). Su radio se ajusta automáticamente a estas condiciones. Cuando esté en operación simple, el icono A aparecerá en la pantalla de cristal líquido (vea la ilustración de la página A3).NOTA Todos los canales vienen programados previamente de fábrica conforme a los reglamentos internacionales y a los de la FCC (EE. UU) e Industry Canada (Canadá). No pueden ser alterados por el usuario, así como tampoco pueden cambiarse los modos de operación entre simple y dúplex.Weather Channel Assignments $VLJQDFLRQHVGHFDQDOHVPHWHRUROyJLFRV 5;)UHTXHQF\0+]1XPEHU 162.550 NOAA 162.400 NOAA 162.475 NOAA 162.425 NOAA 162.450 NOAA 162.500 NOAA 162.525 NOAA 161.650 Canada 161.775 Canada 163.275 NOAA9+)0DULQH&KDQQHO$VVLJQPHQWV(QJOLVK$VLJQDFLyQGHFDQDOHVGH9+)SDUDUDGLRFRPXQLFDFLyQPDUtWLPD(VSDxRO](https://usermanual.wiki/Cobra-Electronics/MRF77.User-Manual-I-Part-2/User-Guide-2526489-Page-20.png)
