2.4GHz数字无线立体声收发器

本版均为无内置电池

包装清单

l 1 *发射机（指示灯为蓝色）

l 1 *接收机（指示灯为绿色）

l 2 *音频线

l 1 *使用说明书

发射器功能说明

①发射天线： 无线信号由此天线发出。

②电源键： 长按3秒后开机；长按3秒后放手即关机。

③状态指示灯： 开机后，此蓝色指示灯常亮。

④配对键： 出厂时发射器和接收器已配对完成，一般情况下无需重新配对。

若发射器和接收器在某些情况下需重新配对，发射机和接收机开机后，均需各自同时长按配对键3秒钟后松开，此时发射机状态指示灯和接收机状态指示灯都会闪烁，配对成功后接收机状态指示灯会由闪烁变为常亮。

注意：发射机在配对模式只有15秒钟的窗口期，无论配对是否成功，15秒钟以后自动退出配对模式，发射指示灯由闪烁状态变为常亮状态，请务必在此15秒钟窗口期内按下接收机的配对键。

支持1拖多。若需一套发射机同时与多套接收机配合使用，则每套接收机均需单独与发射机重新配对一次。

⑤音频输入插孔： 请用随机附带的音频转接线插入此插孔，通过音频转接线与音源设备输出端口对接。

⑥电源接口： 供电电压5V，使用随机附带的5V 1A电源适配器供电。

接收器功能说明

①接收天线： 无线信号由此天线接收。

②电源键： 长按3秒后开机；长按3秒后放手即关机。

③状态指示灯： 开机后若接收到发射信号，则此绿色指示灯常亮，若没有接收到发射信号，则此绿色指示灯慢速闪烁。

④配对键： 出厂前发射器和接收器已配对完成，一般情况下无需重新配对。若需重新配对，请按照发射器功能说明里相关介绍操作。

⑤音频输出插孔： 请用随机附带的音频转接线插入此插孔，通过音频转接线与音响设备的信号输入端口对接。

⑥电源接口： 供电电压5V，使用随机附带的5V 1A电源适配器供电。

注意事项

1、发射器使用时应避免放置于死角以保持发射信号质量良好；

2、接收器使用时尽量避免放置于距离无线路由器较近的位置，以免接收信号被干扰导致声音出现中断现象（特别忌讳接收器紧挨着无线路由器放置）；

3、由于本产品的数字调制为无线双向传输，接收机在接收信号的同时也会对外发射信号，此发射信号可能会对极少部分型号的音频功放产生干扰导致音频底噪升高，如发现此类情况，请将接收机挪动下位置，规避干扰影响。

4、本品由零件构成，请勿抛、扔、丢等以免造成严重损坏；

5、机身不防水，应避免水滴直接入机身或日晒雨淋；

6、尽量远离电磁声场、高压输电网、大件金属物；

.4GHz Digital Wireless Stereo Audio Transceiver 

Packing list：

l 1 *Transmitter（Blue indicator light）

l 1 *Receiver（Green indicator light）

l 2 * Audio Line

l 1 * User Guide

Transmitter function description

①  Transmitting antenna:  The wireless signal is sent by this antenna.

②  Power button:  Press and hold for 3 seconds to turn it on; press and hold for 3 seconds to turn it off.

③  Status indicator light:  This Blue indicator light is always on after power on.

④  Pairing button:  The transmitter and receiver are paired and completed in the factory, and the normal application does not need to be re-paired.

           In some cases, if the transmitter and receiver need to be re-paired,, they all need to press the pairing button for 3 seconds at the same time after booting up.You will see both the transmitter status indicator light and the receiver status indicator light flashing.When the pairing is successful, the receiver status indicator light will change from blinking to steady.

Tips: The transmitter is only 15 seconds in the pairing mode. Regardless of whether the pairing is successful or not, the transmitter will automatically exit the pairing mode after 15 seconds, and the transmitting indicator light will change from blinking to steady state. Be sure to press the receiver's pairing button within 15 seconds.

If one transmitter is required to be used in combination with multiple receivers, each receiver must be re-paired separately with the transmitter.

⑤  Audio input port:Plug the audio extension cable into this port and connect it to the audio device output port through the audio extension cable.

⑥  Power input port:  5V supply voltage, powered by 5V 1A power adapter.

Receiver function description

①  Receiving antenna :  The wireless signal is received by this antenna.

②  Power button :  Press and hold for 3 seconds to turn it on; press and hold for 3 seconds to turn it off.

③  Status indicator light :  If the receiver receives a signal after startup, the Green indicator light is always on. If no signal is received, the Green indicator light flashes slowly.

④  Pairing button :  The transmitter and receiver are paired and completed in the factory, and the normal application does not need to be re-paired.

     If you need to re-pair, follow the above process for pairing。

⑤  Audio output port :  Plug the audio extension cable into this port and connect it to the signal input port of the audio amplifier via an audio extension cable.

⑥  Power input port :  5V supply voltage, powered by 5V 1A power adapter.

warning

1、Do not place the transmitter at a dead angle to keep the transmitted signal quality good.

2、When using the receiver, try to avoid placing it closer to other wireless transmitters,in order to avoid the interruption of the sound caused by the interference of the received signal.

3、The digital modulation of this product is wireless bidirectional transmission, and the receiver will also transmit signals when receiving signals.

For very few models of audio amplifiers, this transmitted signal may interfere with the audio and cause the noise floor to rise, if the audio is found to be disturbed, move the receiver to avoid interference effects.

4、This product is made up of precision parts, Do not throw, throw, throw, etc. to avoid serious damage.

5、This product is not waterproof, do not let water directly into the inside of the casing.

6、Try to stay away from the electromagnetic sound field, high-voltage transmission network, and large metal objects.
