The geomagnetism may be out of alignment. Please calibrate. The geomagnetic sensor is built into both the controller (BO-IC400/BO-IC400N) and the headset.

The calibration method is the same for both headsets and controllers.To calibrate, while the app is running, hold the unit (headset or controller) with the sensors used by the appand draw a figure eight in space. Check with the app vendor about the geomagnetic sensor used by the app.When calibrating the headset, the headset must be turned on, so be sure to connect it to the host device.

If the headset is BT-35E, please follow the instructions below to save the calibration data.

  1. Keep BT-35E charging with USB micro B cable.
  2. Draw the infinity sign when it is image-input from a host device.
  3. Remove the image-input cable, 'No Signal' will be displayed on BT-35E.

The power supply of the device will be temporarily cut off, if you remove the USB microB when it is used as a power feed unit. The sensors will be deactivated. Please reconfigure the settings of the connected device if it is necessary.

This is managed by the application software on the connected device through the USB Type-C™ connection. The software must be compliant to the UVC1.1 standard.
