接收机的操作：
1. 将电源适配器插头插入供电插座, 注意电压是否是交流220V/50~60Hz.
2. 打开电源开关,电源指示灯亮.
3. 拉出天线A和B,使之与机体成90度角.
4. 音频输出的连接:本接收机音频输出采用自动选择输出电路,如果需要混合输
出,则只要用一条音频输出线与任何一个输出插座连接即可. 如果需要独立
输出,则需再连上另一音频输出线即可.
5. 当手持麦克风或领夹发射器开机后,接收机"RF"信号灯亮,接收机输出音量大
小,可由音量控制旋钮调整.
6. 若长期不使用请拔出电源转换器.

Check if the adaptor is well connected, and if the
socket is broken.
The RF indicator
lights while speaking,
but no output signal
is available.
“ ” Check if the power switch is in the middle

distance gets shorter,
the signal becomes
unstable.
1. Put out the antenna.
2. Check if the batteries are running off and
replace them with the fresh ones if needed.
3. Check if the receiver is put in inappropriate
position, i.e. on the ground or at the corner of
the wall or in a strong electromagnetic filed,
please change its position.
Remarks: If there are any other troubles or problems observed, please
do not open and repair it by yourselves. Please, first contact our distributors
or directly come back to us. We will try our best to provide you with
professional and efficient service.
Sound quality gets
worse.
1. The battery of the microphone is running off,
please replace it with fresh one.
2. Check if there is same frequency signal
problem, do not use two units with same
frequency at the same time in the same area.
(The distance must be at least 100m between
two units with same frequency.)
