6. הוראות הפעלה
6.1 פעולה בסיסית
- הפעלה/כיבוי: סובב את ה בקרת עוצמה/עוצמת קול clockwise to turn the radio on. Continue rotating to adjust the audio volume.
- כוונון סקווש: סובב את ה בקרת רמת סקוולץ' clockwise until background noise disappears. Rotate counter-clockwise to hear weaker signals.
- בחירת ערוץ: השתמש ב- מתג ערוץ הכפתור בפאנל הקדמי או ב ערוץ למעלה/למטה buttons on the microphone to select your desired operating channel.
6.2 Modulation Modes (AM/FM/SSB)
השתמש ב- PA/FM/AM/USB/LSB Mode selector to choose your desired modulation mode:
- AM (Amplitude Modulation): Common for local communication.
- FM (Frequency Modulation): 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.
