Notes on the Bluetooth function

In this topic, [Bluetooth devices] refers to all Bluetooth-compatible devices.

Bluetooth-compatible devices are audio devices that support the Bluetooth function.

  • Depending on the Bluetooth device, network environment, and surrounding conditions, noise may be heard or the sound may be interrupted. To optimize Bluetooth communications, observe the following.
    • Place the player and the Bluetooth device as close together as possible. The Bluetooth standard supports distances of up to 10 meters (32.8 feet).
    • Turn the built-in Bluetooth antenna (aerial) in the direction of the connected Bluetooth device.
    • Do not block the antenna (aerial) with a metal object such as a bag or case.
    • Do not block the antenna (aerial) with a body part such as a hand.
    • Do not block the antenna (aerial) by placing the player inside a backpack or shoulder bag.
    • Do not block the antenna (aerial) by using the player in a crowded place.
    • Avoid areas where electromagnetic waves are emitted. For example, near microwave ovens, mobile phones, or mobile gaming devices.
  • Bluetooth audio equipment and wireless LANs (IEEE 802.11b/g/n) use the same frequency band (2.4 GHz). If you use the player near a device equipped with a wireless LAN, radio-wave interference may occur. It may cause a decrease in connection speed, noise, or connection failure. In this case, take the following measures.

    • When connecting the player to a Bluetooth audio device, keep the player at least 10 meters (32.8 feet) away from any device equipped with a wireless LAN.
    • Keep the player and Bluetooth audio device as close as possible.
    • When using the player within 10 meters (32.8 feet) of a device equipped with a wireless LAN, turn off the power of the wireless LAN.
  • Due to a characteristic of Bluetooth wireless technology, the sound may lag slightly.

  • Bluetooth radiation may affect the operation of electronic medical devices.

    Turn off the player and other Bluetooth devices in the following locations.

    • in hospitals
    • near priority seats on trains
    • on airplanes
    • in places where flammable gases are present (gas stations, etc.)
    • near automatic doors
    • near fire alarms
  • The player supports security functions that comply with the Bluetooth standard. Sony bears no responsibility whatsoever for information leaks that occur as a result of your Bluetooth connection.

  • Even if a Bluetooth device conforms to the standard, all connections and correct operations are not guaranteed.

  • Depending on the Bluetooth device, it may take some time to establish a Bluetooth connection.
