6. Istruzioni per l'uso
6.1 Funzionamento di base
- Accensione/spegnimento: Ruotare il Controllo accensione/volume clockwise to turn the radio on. Continue rotating to adjust the audio volume.
- Regolazione dello squelch: Ruotare il Controllo del livello di squelch clockwise until background noise disappears. Rotate counter-clockwise to hear weaker signals.
- Selezione canale: Utilizzare il Cambio canale manopola sul pannello frontale o Canale su/giù buttons on the microphone to select your desired operating channel.
6.2 Modulation Modes (AM/FM/SSB)
Utilizzare il PA/FM/AM/USB/LSB Mode selector to choose your desired modulation mode:
- SONO (AmpModulazione di intensità): Common for local communication.
- FM (modulazione di frequenza): Offers clearer audio over shorter distances.
- USB (Upper Sideband) / LSB (Lower Sideband): Used for long-distance SSB communication. Fine-tune with the SSB Frequency FINE Function.
- PA (Public Address): Outputs audio to an external PA speaker.
