microwave interference may occur and result in noise, audio dropouts, or communications being disabled if this
headset is used near a wireless LAN device. In such a case, perform the following steps.
When connecting the headset to a Bluetooth device, use the headset at least 10 m (30 feet) away from the
wireless LAN device.
If this headset is used within 10 m (30 feet) of a wireless LAN device, turn off the wireless LAN device.
Use this headset and the Bluetooth device as near to each other as possible.
If you are enjoying music with your smartphone or computer, the situation may be improved by shutting down
unnecessary apps or restarting playback devices such as your smartphone or computer.
Connect the headset and the Bluetooth device once again.
