NOTE
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).
