To pair an Oculus Quest 2 with a CITYCALL I8550:
Make sure your CITYCALL I8550 is compatible with Oculus Quest 2: Oculus Quest 2 requires a phone with Android 6.0 Marshmallow or higher to run the Oculus app, which is used to set up and manage the headset.
Install the Oculus app on your CITYCALL I8550: Go to the App Store or Google Play Store and search for "Oculus". Download and install the Oculus app on your phone.
Turn on your Oculus Quest 2 headset: Press and hold the power button on the headset until the Oculus logo appears.
Open the Oculus app on your CITYCALL I8550: Launch the Oculus app on your phone and tap on "Get Started".
Follow the on-screen instructions: The app will guide you through the process of setting up your Oculus Quest 2 and connecting it to your CITYCALL I8550. You will need to create an Oculus account if you don't already have one, and you will need to allow the app to access your phone's Bluetooth and location services.
Pair the headset with your CITYCALL I8550: The app will prompt you to put the headset into pairing mode. To do this, hold down the volume down button and the power button on the headset at the same time until the pairing screen appears. The app will then search for available headsets and display a list of devices. Select your Oculus Quest 2 headset from the list and follow the on-screen instructions to complete the pairing process.
Once paired, you can use your CITYCALL I8550 to manage your Oculus Quest 2 headset and access the Oculus Store to download games and apps.
