• Do not connect or disconnect the headset while it is operating.
• Make sure you unplug the dedicated micro-USB power supply cable before unplugging the headset cable.
• HDMI cannot be connected using a conversion adapter.
• To prevent excessive wear on the connectors, do not disassemble the AC adapter once it has been assembled.

Connecting by USB Type-C

When connecting to an external device with USB Type-C, you can use data from the headset sensors and camera as well as view the images. Also, since it can be used as a power supply source, you can perform three operations simultaneously using one USB Type-C cable; input video signals, output sensor/camera data, and supply power.

1. Use both hands to open the temples, and then put lead on the headset.
   
   Do not use too much force when opening the temples of the headset.
2. Adjust the position of the headset so that you can see the image.
   

• How an image is perceived varies depending on the individual.
• You can connect earphones and microphones using the 3.5 mm audio jack.
  Use earphones that conform to the CTIA standard.
  You may hear some noise if the cables are disconnected or connected while content is being played.
  
  You can clip the headset cable to your clothes.

Make sure the cable does not catch on anything in the surrounding area while wearing the product. Also, make sure the cable does not wind around your neck.

Wearing over Glasses

The headset can be worn over glasses. (The headset can only be worn over glasses that are approximately 5.8 inches [147 mm] wide.)

• Make sure that you do not damage the glasses and the lens of the headset when wearing.
• You may not be able to wear the headset over the glasses depending on the shape of your glasses.

The nose pads fit over your glasses.

Using the Shaded Shield

➡ "Interface Unit"

Using the Belt Clip/Cable Retainer

You can attach the interface unit to the belt by using a belt clip or cable retainer.

You can also secure extra cables to the cable retainer by using a commercially available band.

1. Attach the belt clip to the interface unit using the screw supplied.
   
   By changing the direction of the belt clip you can rotate the interface unit by 90 degrees.
   
   Loosen the screw to lift and rotate the clip. Attempting to rotate the clip without loosening the screw will damage the clip and interface unit.

3. Attach the clip to a belt and so on.
   
   Use the same procedure to attach the cable retainer to the belt. You can secure other cables using commercially available bands and so on so that they do not catch on anything in the surrounding area.
   

• Keep the cables as close to your body as possible. Sagging cables may cause accidents or injuries if they become caught or trapped by surrounding objects.
• Do not pull the headset's cable. If the headset comes off, it may result in accident or injury.
• Since the belt clip/cable retainer are designed to grip the belt securely, they could scratch the surface of the belt during attachment or removal. Avoid attaching them to leather or shiny belts, or protect the belt by placing a thin cloth over the section they come in contact with.
