This video is a step-by-step process on how to use the Razer Nari Pairing Utility.
The Razer Nari Pairing Utility is software that is included with the purchase of a new wireless USB
dongle.
It is designed to pair the new dongle with an existing Nari headset. It can also be used to fix an issue
when the headset is not connecting.
First, run the Razer Nari Pairing Utility. By default, it is located in the downloads folder of your
computer. When prompted to close synapse and other applications, follow the on-screen instructions,
and click OK and plug in the wireless USB dongle to your PC.
Next, connect the headset to your computer using the charging cable.
Lastly, hit the pair button and wait until the progress bar reaches 100%.
After it's paired you may close the window.
