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 A2).
