To connect the Lingo headphones to the audio device, follow these steps:
Step 1: Turn on the headset. On the first use, the headset will enter pairing mode automatically. Otherwise, with the headset turned off, press and hold the multi-function button for 5 seconds until the LED flashes blue and red alternately to put it into pairing mode.
Step 2: Turn on the Bluetooth on your device and select "Avantalk Lingo" from the Bluetooth menu.
Step 3: Keep the two devices close together. Once connected successfully, the headset's LED will become solid blue. You will hear a "Connected" voice indicator.
For subsequent use, your headset should automatically reconnect to the last paired device within a few seconds after turning on. If not, you can manually reconnect by pressing the multi-function button once or by selecting "Avantalk Lingo" from your device's Bluetooth menu.
