Notes ※1. Internal input resistance of volt-ohm meter should be higher than 10k-ohms.
テスターは、入力抵抗10kΩ以上のものをお使い下さい。
※2. Adjustments should be made in case of the PC Board or Transistors being changed.
調整はPCボードあるいはトランジスタを交換した場合に行って下さい。
※3. After feeding 1～10 watts output for about 15 minutes, check bias adjustment again.
出力1～10ワット前後で通電動作させた後、バイアス電流を再チェックします。
