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 HT3187:
Clear paired history of the transmitter:
- Enter the transmitter into pairing mode - Press and hold the MFB for 5 seconds until LED flashes RED and BLUE.
- Press and hold the MFB for 5 seconds until the BLUE LED is on for 2s.This clears all of the paired history of the transmitter except for the HT3187 receiver. Transmitter will then automatically enter pairing mode with the LED flashing RED and BLUE alternately.
Clear paired history of the receiver:
- After turning on, press and hold “+” and “-” for 10 seconds until BOTH RED and BLUE LEDs turn on for 2 seconds (looks PINK), now all paired history of the receiver is cleared, then the receiver will automatically enter pairing mode and the LED flashes RED and BLUE.
