1. Power up the transmitter – You can connect the transmitter to the TV’s USB port or any other power source that supports 5V/500mA-2A via the provided USB cable. Turn on the transmitter by sliding the power switch to the “ON” position.
Contact us at support@avantree.com for a free wall-plug adapter if you need one.
2. Charge and power on the headphones - When you see the LED of the headphones flashing RED, it means they are low battery, and you need to charge them.
You can charge them using a phone charger (5V/500mA-2A output), PC USB port, TV USB port or any other USB outlet using the provided USB cable. It takes about 3 hours to fully charge the headphones. The LED will turn RED during charging and automatically turn off once charging is complete. After fully charged you can slide the Power Switch to "ON" to power it on.
Note: Starting from Batch number T22H1, the charging port on the Quartet headphones has been changed to a Type C port.
