Pressing the PRESET key toggles between Preset Channel A, b, C, d, E, and the last selected “regular” channel. Preset Channel A is represented by “A” to the left of the channel number on the LCD, and channel B is repre- sented by “b,” and so forth. The letter “A” should not be confused with the “A” that sometimes is displayed to the right of the channel number (described in the section 3.2 of this Owner’s Manual).

All channels are factory-programmed in accordance with FCC (USA), In- dustry Canada and International regulations. The mode of operation cannot be altered from simplex to duplex or vice-versa. Simplex or duplex mode is automatically activated, depending on the channel and whether the USA, International or Canadian operating band is selected. Refer to the channel charts in the OWNER’S MANUAL SUPPLEMENT.
