Bluetooth connection precautions

The following environments affect the range and reception of Bluetooth signals:

• - When walls, metal, human bodies, or other obstacles exist between the Bluetooth device and the connected device.
• - When equipment that uses 2.4 GHz frequency signals (wireless LANs, wireless phones, microwave ovens, etc.) is placed near the devices being used.
• - When using a Bluetooth device (TV, laptop, etc.) other than the mobile phone, the sound quality may be affected by the specifications and performance of the device.
