Using Instruction:
- First, connect the antenna to the transmitter and tighten it, then connect it to the power supply.
- Supports simultaneous audio transmission in two modes. When external audio input (AUX/RCA) is used, USB/Bluetooth/TF card audio sources are also supported, meaning the receiver will receive sound from both types of audio sources.
- Working sequence of Bluetooth module. TF card > USB >Bluetooth. When a TF card is inserted, the other two modes will be interrupted until the TF card is removed. When a USB is inserted, the Bluetooth mode will be interrupted until the USB is removed and Bluetooth needs to be reconnected. When a TF card or USB is inserted into the module, Bluetooth cannot be connected and the TF/USB needs to be removed to connect and use Bluetooth. Bluetooth name: HW-BT.
- When using Bluetooth, the volume will decrease and accompanied by slight noise, which is a normal phenomenon. Simply turn down the volume of the receiver and increase the volume of the transmitter appropriately, especially when outputting the receiver to the speaker through an audio power amplifier mode.
- The microphone is sensitive, please adjust the volume knob appropriately, otherwise it may produce noise. If you do not use the microphone function, please turn off the volume adjustment or remove the microphone.
