6. 操作手順
6.1 基本操作
- 電源オン/オフ: 回転する 電源/音量コントロール clockwise to turn the radio on. Continue rotating to adjust the audio volume.
- スケルチ調整: 回転する スケルチレベルコントロール clockwise until background noise disappears. Rotate counter-clockwise to hear weaker signals.
- チャンネル選択: 使用 チャンネルスイッチ フロントパネルのノブまたは チャンネルアップ/ダウン buttons on the microphone to select your desired operating channel.
6.2 Modulation Modes (AM/FM/SSB)
使用 PA/FM/AM/USB/LSB Mode selector to choose your desired modulation mode:
- 午前 （Amp光度変調): Common for local communication.
- FM（周波数変調）: 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.
