How to make a wireless connection to Bluetooth devices.

System requirements for battery charge using USB.

What you can do with the Bluetooth function.

Refer to the operating instructions supplied with your computer for computer operation. Or, operate the computer to make an A2DP connection. If the sound quality does not improve after a few seconds, press the button on the headset once during playback. This is caused by the computer transmitting music at sound quality for communications at first, and it is not a malfunction. When you listen to music from a computer on the headset, sound quality may be reduced (e.g., hard to hear a vocalist's voice, etc.) for the first few seconds after a connection is made. If this happens, use the Bluetooth device and make an A2DP Bluetooth connection.

If you have previously connected the headset to this Bluetooth device, only an HFP/ HSP Bluetooth connection may be made when the headset is turned on.

Move the headset away from the connected device and try again.

If you connect a device with a built-in radio or tuner to the headset, broadcasts may not be received, or sensitivity may be reduced.

Switch the Bluetooth connection to A2DP by operating the Bluetooth device when HFP or HSP is set.

Remove any obstacles between the headset and the Bluetooth device.

Bring the headset and the Bluetooth device closer together.

Keep the headset away from microwave ovens, Wi-Fi devices, etc.

Turn down the volume if it is too loud.
