3. ته ځواک پلي کړئ ampلایف بورډ
4. Start playing audio from your connected source.
5. Slowly adjust the volume potentiometer clockwise to your desired listening level.

7. ساتنه

• پاکول: Keep the board clean and free from dust. Use a soft, dry cloth for cleaning. Avoid using liquids or solvents.
• وینټیلیشن: Regularly check that the heatsink is not obstructed and has sufficient airflow to prevent overheating.
• اړیکې: Periodically inspect all wiring connections to ensure they remain tight and secure.
• ذخیره کول: کله چې د اوږدې مودې لپاره په کارولو کې نه وي، ذخیره کړئ amplifier board in a dry, cool environment.

8. ستونزه حل کول

• غږ نشته:
  • Check power supply connections and ensure the power source is active.
  • Verify audio input cable is securely connected to both the source and the ampلايف
  • ډاډ ترلاسه کړئ چې د سپیکر تارونه په سمه توګه وصل دي او لنډ سرکټ شوي ندي.
  • Increase the volume using the potentiometer.
• تحریف شوی غږ:
  • Reduce the volume from both the audio source and the ampلايف
  • Check speaker impedance; ensure it is within the 4-8 ohm range.
  • Verify the audio source is not overdriving the input.
• ډیر ګرمول:
  • Ensure adequate ventilation around the heatsink.
  • Reduce the output volume or operating time.
  • د بریښنا رسولو حجم تایید کړئtage ډیر لوړ ندی.
