1. Model: RT012. Technology: BT5.0, A2DP, AVRCP3. Operating range: maximum 10m / 33ft (no blocking objects)4. Match name: RT015. Charging time: 2 hours, working time: 12 hours6. Battery type: Lithium polymer (400mAh)7. Size: 65x45x21mm, Weight: 40g8. Package contents :1 x Bluetooth 5.0 audio Transmitter/receiver adapter 1x Micro USB power cord 1X RCA cable 1X 3.5mm auxiliary cable 1X User manual9. Power on: Press and hold the power on/off button until the LED lights on/off: press and hold the power on/off button until the LED goes off10. Charging: Use DC-5V charger and Micro USB charging cable. The red light goes on when charging. When the battery is fully charged, the red light goes out.11. Switching mode: (RX: receiving mode, indicator light: blue LED) (TX: transmitting mode, indicator light: red LED)12. RX mode:The receiving mode can be used in the home, car and other scenes, enabling speakers without Bluetooth function to have Bluetooth function, realizing wireless connection with mobile phones, tablets and other devices, saying goodbye to the cable bondage.13. How to use:1) First switch RT01 to receive mode (RX), pair name: RT01, and find the RT01 pair in the Bluetooth Settings of the mobile phone. The blue light flashes twice every second during the pairing and once every three seconds after the pairing is successful.2) Insert one end of the audio cable into the audio input end of the speaker and the other end into the audio input end of the RT01. Then you can play the music.14. TX mode:The transmit mode can be used on non-Bluetooth sound source devices such as computers and televisions to help these devices transmit sound to Bluetooth speakers and headsets. TX mode will automatically search for other Bluetooth receiver devices (such as Bluetooth headset, Bluetooth speaker, bluetooth receiver, etc.), and the red light will blink twice every second during the pairing process and once every three seconds after the pairing is successful.15. Use:1) Insert one end of the audio cable into the audio output end of the device and the other end into the audio input end of the RT01.2) Make sure it is in TX mode (red flashing). The RT01 will automatically search for Bluetooth headsets or Bluetooth speaker pairs. Once paired, a TV or computer voice can be transmitted to a device such as a Bluetooth speaker via the RT01.16. Bluetooth speakerphone call: In RX receiving mode, this product supports Bluetooth speakerphone call. When the phone calls, click the M button to answer the call.
