6. Gebruiksaanwijzing
6.1 Basisbediening
- Aan/uit: Draai de Stroom-/volumeregeling clockwise to turn the radio on. Continue rotating to adjust the audio volume.
- Squelch-aanpassing: Draai de Squelch-niveauregeling clockwise until background noise disappears. Rotate counter-clockwise to hear weaker signals.
- Kanaalselectie: Gebruik de Kanaal wisselen: knop op het voorpaneel of de Kanaal omhoog/omlaag buttons on the microphone to select your desired operating channel.
6.2 Modulation Modes (AM/FM/SSB)
Gebruik de PA/FM/AM/USB/LSB Mode selector to choose your desired modulation mode:
- BEN (Ampamplitudemodulatie): Common for local communication.
- FM (Frequentiemodulatie): 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.
