How to Enter Bluetooth Pairing Mode
Step 1: Entering Pairing Mode on the HS134 Headphones.
Make sure that the headphones are off. From there, hold the power button for about 5 seconds until the LED indicator alternates between flashing RED & BLUE.
Note: If you are turning on the headphones for the first time, the headphones will automatically go into pairing mode (the LED will flash RED & BLUE.)
Step 2: Connect the Headphones.
In the Bluetooth settings, locate "Avantree HS134". If the headphones are in pairing mode, it should say "Ready to pair" underneath "Avantree HS134". Click "Pair" to connect the headphones.
After connecting the headphones, the LED on the headphones will turn SOLID BLUE. On your device, there may be a pop-up indicating that you are connected. Otherwise, you can check the Bluetooth settings and "Avantree HS134" should appear as connected.
