CONVENTIONAL MODE OPERATION

The radio functions in the conventional mode when using conventional com-
munications channels (non-trunked). Each channel consists of a preset fre-
quency pair for transmit and receive during repeater operation, or a single
frequency for both transmit and receive during talk-around (no repeater) op-

channel is selected.
The button unmutes the receiver so activity on the selected channel can

Guard or T99) on and off if programmed for the selected channel.
