NOTE

Many of the plain numbered channels, such as 01, 02 and 03, transmit on one frequency and receive on another. 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 A2).
