Notes on the Bluetooth function

In this topic, [Bluetooth devices] refers to all Bluetooth-compatible devices. Bluetooth-compatible devices are audio devices, smartphones, etc. 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 Walkman 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 Walkman inside a backpack or shoulder bag.
    • Do not block the antenna (aerial) by using the Walkman in a crowded place.
    • Avoid areas where electromagnetic waves are emitted. For example, near microwave ovens, mobile phones, mobile gaming devices, or wireless LAN environments.
  • The battery life may become about 45 % shorter if you activate certain sound quality settings (for example, [Equalizer] or [DSEE HX] under [Sound Settings]) while you are using the Bluetooth Receiver function. The battery life also depends on the volume, conditions of use, and surrounding temperature.
  • 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 Walkman 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 Walkman 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.
