USB Type-C connector to the connected device.
Connect commercially available earphones to the earphone jack.

You may hear some noise when connecting or disconnecting the earphones or USB Type-C connector during content playback, so be sure to take off your earphones first.
- When using apps with a call function, phone calls may be audible from the smart device even if earphones are connected. We recommend checking in advance what happens when you receive a phone call while images are displayed.
Put on the headset and earphones, and then adjust the position of the headset so that you can see the image.

You can clip the earphone jack to your clothes using the clip. Note that some clothes may be damaged by the clip.

DisplayPort Alternate Mode.
If you are using an Android device, you can adjust the brightness of the

Adjust the volume on your connected device.
Difficult to View the Screen in Bright Surroundings
You can view the screen easily by attaching the shade supplied. The shade is
magnetic and can be attached and removed easily.
When Wearing over Glasses
You can wear the headset even if you wear glasses.
- Make sure that you do not scratch the headset or your glasses when wearing them.
- The headset cannot be worn over glasses that are wider than approximately 144 mm (5.7 inches).
- You may not be able to wear the headset over the glasses depending on the shape of your glasses.
The nose pad for glasses is worn on the nose from over the glasses.
Replacing Nose Pad
When replacing the nose pad, be sure to purchase the option for the BT-40.
Pull the nose pad straight towards you to remove and replace them.
Cleaning the Headset
-
If you can see dirt on the screen or if it is foggy, check the lens for dirt such as dust or fingerprints.
If there is any dust or dirt attached to the lens, wipe it off with a soft cloth.
When wiping the lens, do not use liquids such as lens cleaning solutions or organic solvents. -
If anything except for the lens is dirty, wipe off the dirt with a wet tissue. Do not use a tissue moistened with alcohol-based cleaning liquid.
When the Accuracy of the Headset’s Sensor is Low
If the accuracy of the sensor is low in apps that use the headset’s
geomagnetic sensor, wave the headset in a figure 8 shape while a smart device
or Intelligent Controller is connected to calibrate the sensor.
