If you are experiencing unexpected issues such as short work range, audio cut in and out, not pairing, etc. you may need to clear the paired history of the HT3189 headphones and transmitter.
Clear paired history of the transmitter
- After turning on, press and hold MFB for 5 seconds until LED flashes RED and BLUE alternately.
- Press and hold the MFB for 5 seconds until BLUE LED is on for 2 seconds. This clears all of the paired history of the transmitter except for the HT3189 headphones. Transmitter will then automatically enter pairing mode with the LED flashing RED and BLUE alternately.
Clear paired history of the headphones
After turning on, press and hold “+” and “-” for 10 seconds until the RED and BLUE LEDs are BOTH on for 2 seconds (looks PINK), now all paired history of the headphones is cleared. It will then enter pairing mode automatically with the LED flashing RED and BLUE alternately.
