B-3 PLUS内置了强大的自动配对功能，请按照如下步骤操作：
1. 按住发射器与接收器的电源按钮直至开机。
2. 发射器与接收器会开始检测射频环境并自动选择最佳的工作
通道完成配对。
3. 将发射器连接至您的动圈式麦克风，将接收器连接至您的调
音台或音箱。
B-3 PLUS正常工作时按发射器的电源按钮一次可以进入“静音模
式”，发射器与接收器的工作指示灯均会长亮红色，此时再按
一次发射器上的电源按钮便可以使B-3 PLUS恢复到正常工作模
式。

开机时，通道指示灯会先显示电池电量然后再显示工作通道。
连接成功后发射器与接收器的工作指示灯均会长亮蓝色。如果
接收器没有接收到信号（受到强烈干扰或超出有效距离），发
射器与接收器的工作指示灯会长亮红色。

电池充电
每次开机，您可以通过通道指示灯来判断发射器与接收器的电
池电量，如下图所示：
当电池电量低于10%时，工作指示灯会亮红色并闪烁10次后自
动关机，此时您需要为本产品充电。充电时，工作指示灯亮红
色，电池充满后工作指示灯会自动熄灭。
我们建议您在电池电量低于15%时就为本产品充电，请使用附
赠的充电线连接电脑USB接口或使用5V/1A USB充电器为本产品充
电。
B-3 PLUS 2.4GHz频率表： 注意
由于本产品内置聚合物锂电池，为了最大限度延长电池使用寿
命，请在初次使用前将电量充满；如果长时间不使用本产品，
请至少每三个月充电一次（避免造成锂电池假性故障）。
