在没有无线电设备的环境下，使用不适合调整手持无线麦克风，而是调整无线麦克风接收器，调整步骤可以是这样的：
In the environment without professional radio equipment, the use of multimedia conference sound is not suitable for adjusting the handheld wireless microphone, but adjusting the wireless microphone receiver. The adjustment steps can be as follows:
打开无线麦克风接收器的盖子，在手持无线麦克风上使用电压较低的旧电池。
Open the cover of the old wireless microphone and use it on the old wireless microphone.
打开手持无线话筒和无线话筒接收器的电源，将手持无线话筒放在胸前，背对着无线话筒接收器，边喊边向远处走，找一个盲音位置，设置这个位置作为盲音参考点。
Turn on the power supply of the handheld wireless microphone and wireless microphone receiver, place the handheld wireless microphone in front of your chest, turn your back to the wireless microphone receiver, shout and walk away, find a blind sound position, and set this position as the blind sound reference point.
关机，在无线话筒接收器的电路板上找到天线接入点，沿着天线输入电路找到个可调电容，或者可调电阻，或者电感，使一个标记到位，并在逆时针或顺时针方向微调一点。
Power off, find the antenna access point on the circuit board of the wireless microphone receiver, find the first adjustable capacitor, or adjustable resistance, or inductance along the antenna input circuit, make a mark in place, and fine tune a little counterclockwise or clockwise.
打开手机，将手持无线话筒放在胸前，背对无线话筒接收器，边喊边走到盲音参考点。如果盲区消失，则调整成功。如果逆时针微调一下，可以改成顺时针方向微调一下，一两次就成功了。
Turn on the mobile phone, put the handheld wireless microphone on your chest, turn your back to the wireless microphone receiver, and walk to the blind reference point while shouting. If the blind area disappears, the adjustment is successful. If you fine tune it counterclockwise, you can change it to fine tune it clockwise, and it will succeed once or twice.
如果在一个场地使用好，换到另一个场地，有时会出现断点或频移的情况。在调试或排练时，如果发现麦克风有问题，一般会微调频率。
If you use it well in one site and change to another site, sometimes there will be breakpoints or frequency shifts. During debugging or rehearsal, if there is a problem with the microphone, it will generally fine tune the frequency.
可以在麦克风电池座的负极焊一根漆包线，有些人不使用充电电池，未充电的电池也可以避免频率下降（因为充电电池的电流低）。
Add a few points. An enamelled wire can be welded to the negative pole of the microphone battery base. Some people do not use rechargeable batteries, and the uncharged batteries can also avoid the decrease of frequency (because the current of rechargeable batteries is low).
在频率下降的地方，接收机可以放在离演员很近的地方，不影响美观，不让人摸不着。
In the place where the frequency drops, the receiver can be placed close to the actor, which does not affect the beauty and cannot be touched.
如果您使用充电电池，您须每使用15分钟更换一次充满电的充电电池。也有不同方向改变接收器的可能，有的还可以避免掉频。
If you use a rechargeable battery, you must replace the fully charged rechargeable battery every 15 minutes. It is also possible to change the receiver in different directions, and some can avoid frequency loss.
