32Basic OperationPerforming CommunicationSelecting Communication ModeThis transceiver is equipped with AMS (Automatic Mode Select) which automaticallyselects between 4 modes of transmission to fit the signal being received. Because thetransmission is automatically adjusted to that of the other station, not only C4FM digitalsignals, but analog signals are also recognized.Press % to display [DN*] on the LCD.* (The display depends on the received signal.)䰢䰒䰛䰢䰒䰛䰢䰒䰛䰢䰒䰛䰒䰙䰒䰙Ā䎧䎱䰔 䰕䰔 䰕䰔 䰕䰔 䰕䰀䯿䯿䯺䯼䯼䯼䰀䯿䯿䯺䯼䯼䯼䯽䰀䰁䯽䰀䰁䯺 䎚䎛 䯼ÿĀÿĀExample of when AMS is displayed.To fix the transmission mode for operation, switch the transmission mode with %.Pressing % toggles between communication modes in the order listed below.[DN (AMS)] [DN (V/D mode)] [VW (FR mode)] [FM (analog)]Operation mode Display Description of ModesAMS(Automatic Mode Select) Transmission mode is automatically selected from 4 typesaccording to the signal received.(“” part differs depending on the received signal.)V/D Mode(Voice/Data simultaneoustransmission mode)DN Call is less prone to interruption due to detection and correctionof voice signals during digital voice signal transmission. This isthe standard mode for C4FM FDMA DigitalVoice FR Mode(Voice Full Rate Mode)VW Digital voice data transmission using the entire 12.5kHz band.Enables high-quality voice communication.Data FR Mode (High SpeedData Communication Mode)High speed data communication using entire 12.5kHz band.This mode is automatically selected for image communication.Analog FM Mode FM Analog communication using FM mode.Effective when the signal is weak and audio is susceptible tointerruption in digital mode.Cautions Digital communication can be performed only on the A-band. Digital communication cannot be performed on the B-band. In V/D mode (“DN” on the LCD), position information is included in the radio wave during voicecommunication, however, it is not include in the Voice FR mode (“VW” on the LCD).
