8. Техникалык тейлөө

  • Тазалоо: Use a soft, dry cloth to clean the surfaces of the receiver and microphones. Do not use liquid cleaners or solvents.
  • Сактагыч: Узак убакыт бою колдонулбаган учурда, микрофондордон батарейкаларды алып чыгып, системаны салкын, кургак жерде, күндүн түз нурунан жана өтө жогорку температурадан алыс сактаңыз.
  • Батареяны алмаштыруу: Replace batteries promptly when the low battery indicator appears on the microphone screen to ensure optimal performance.
  • Антенналар: Антенналарды ийилип же сындырып албаш үчүн этияттык менен кармаңыз.

9. Кыйынчылыктарды

  • Үн жок:
    a. Ensure the receiver is powered on and connected correctly to your audio system.
    b. Check that microphones are powered on and have fresh batteries.
    c. Verify that microphones are synchronized with the receiver (refer to Section 6.2).
    d. Adjust the volume knobs on the receiver.
  • Тоскоолдук/Начар сигнал:
    a. Ensure a clear line of sight between microphones and receiver.
    b. Try changing the frequency channel on the receiver and re-syncing the microphones.
    c. Keep the receiver away from other wireless devices or sources of electromagnetic interference.
  • Feedback (Squealing Sound):
    a. Activate the anti-feedback function on the receiver (refer to Section 6.3).
    b. Reduce the microphone volume or move the microphone further away from speakers.
  • Microphone Not Muting:
    a. Ensure you are pressing the correct switch on the microphone to activate the mute function. The screen should display "AF OFF".

10. Колдонуучунун кеңештери

  • Connecting to Computers: The receiver's audio output is a 1/4" (6.3mm) jack. If connecting to a computer's 3.5mm microphone input, you will need a 6.3mm to 3.5mm adapter (not included).
  • Батареяны алып салуу: The microphone battery compartment is designed to hold batteries tightly to prevent movement. When removing batteries, you may find them slightly difficult to extract.
  • Anti-feedback Effectiveness: The anti-feedback suppressor is effective against general feedback. For severe feedback issues, adjust microphone placement and system gain settings in addition to using the anti-feedback feature.
