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).

NOTE
All the listed channels are pre-programmed at the factory according to
international regulations, those of Industry Canada (Canada) and those
of the FCC (U.S.A.). They cannot be altered by the user nor can modes
of operation be changed between simplex and duplex. In some countries,
additional channels are available. These can be programmed on the
radio by the local dealer or distributor.
