Notes on the Bluetooth function

The following are notes regarding use of the Bluetooth function.
  • Bluetooth wireless technology allows connection at as distance of up to about 10 meters. However, the effective range may vary depending on obstacles (people, metals, wall, etc.) or signal status.

  • The following conditions may cause noise, sound break or playback speed change with a Bluetooth connection.

  • Using inside a metal case

  • Using inside a backpack or other bag held on the back or shoulder

  • Using in locations where a wireless network is in place, microwave oven is in use, or other electromagnetic waves are produced

  • Because Bluetooth and wireless LAN (IEEE802.11b/g) devices use the same frequency (2.4 GHz), signal interference may occur that results in communication speed deterioration, noise, or inability to connect if Bluetooth communications is used near a wireless LAN device. In such a case, perform the following.

  • Perform Bluetooth communications at least 10 meters away from the wireless LAN device when connecting your Walkman and a Bluetooth device.

  • Place your Walkman and the Bluetooth device as close together as possible.

  • Turn off the wireless LAN device when performing Bluetooth communications within about 10 meters of a wireless LAN device.

  • Due to a characteristic of Bluetooth wireless technology, the sound played on the receiving Bluetooth device is slightly delayed from the sound of the sending device.

  • Radio waves emitting from a Bluetooth device may affect the operation of equipment such as electronic medical devices. Turn off your Walkman and other Bluetooth device in the following locations, as failure to do so may cause an accident.

  • In hospitals, near priority seats on trains, in airplanes, in places such as gasoline stations where flammable gases are present, near automatic doors or fire alarms

  • Your Walkman supports security functions that comply with the Bluetooth standard to provide a secure connection when Bluetooth technology is used, but security may not be sufficient depending on the settings. Be careful when connecting using Bluetooth technology.

  • Sony bears no responsibility whatsoever for information leaks as a result of using Bluetooth technology.

  • Your Walkman is not guaranteed to connect with all Bluetooth devices.

  • Bluetooth devices you connect to must conform to the Bluetooth standard specified by Bluetooth SIG and be certified.

  • Even if the connected device conforms to the above-mentioned Bluetooth standard, some devices may not be connected or work correctly depending on the features or specifications of the device.

  • Depending on the device to be connected, the Bluetooth connection may take some time to establish.

Notes on the built-in antenna

  • Your Walkman is equipped with an antenna. The sensitivity of the Bluetooth connection will improve by facing the antenna part towards the connected Bluetooth device. The effective range of the connection will differ if obstacles are between the Walkman and the Bluetooth device.

  • Do not cover the antenna with your hand or other object when connected with the Bluetooth connection. Doing so may obstruct the Bluetooth connection.
