Product Model: AB-2425
Pls note that "AB-2425 LI TX RX " which the RX built in battery.
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.

Transmitter function description
① Transmitting antenna: The wireless signal is sent by this antenna.
② Power button: Press and hold for 2 seconds to turn it on, Press and hold for 2 seconds to turn it off.
③ Status indicator light: This Red 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 2-3 seconds after booting up. The Red status indicator light of transmitter will flashing. When the pairing is successful, The Green signal indicator light of receiver will flash three times in succession, It will automatically exit the pairing state and get into the normal receiving mode.
If more than one Receiver is needed, The transmitter needs to be in pairing mode until all receivers have been paired, All other receivers will be paired one by one in the same way. When all the receivers have been paired successfully, Turn off and reboot the Transmitter,
Tips: Please do not press and hold the pairing button for a long time. It is recommended to press and hold the pairing button for 2-3 seconds to release the hand. Excessive pressing time may cause misoperation.
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.
