Manually Pairing the Headset and USB Adapter

While the headset is powered off, hold down the power button until the headset earcup LEDs starts blinking rapidly. The headset is now in pairing mode.

While the USB adapter is plugged in, use a small tool (e.g. paper clip, SIM tray ejector, etc.) to hold down the button inside the pin hole until the USB adapter LED starts blinking rapidly. The USB adapter is now in pairing mode.

Wait until both the headset LEDs and the USB adapter LED are solid. The headset and USB adapter are now paired together.
