Notes on the Bluetooth function
- Bluetooth wireless technology allows connection at a distance of up to about 10 meters. However, the effective range may vary depending on obstructions (people, metals, walls, etc.) or signal status.
-
The Bluetooth antenna (aerial) is built into your Walkman.
You can improve the sensitivity of Bluetooth communications by turning the built-in Bluetooth antenna (aerial) in the direction of the connected Bluetooth device. The communication distance shortens if there are obstructions between the connected device and the Walkman.
-
The following conditions may cause noise, breakup of sound, or changes in playback speed.
- When using inside a metal bag.
- When using inside a backpack or shoulder bag.
- When using in an area with a wireless LAN, in an area where devices such as microwave ovens, mobile phones and mobile gaming devices with a communication function are in use nearby, or in other areas where electromagnetic waves are being emitted.
-
When the antenna (aerial) built into your Walkman is covered by your hand or blocked by people in situations such as riding in a crowded train.
- Because Bluetooth and wireless LAN (IEEE802.11b/g) devices use the same frequency (2.4 GHz), signal interference may occur, resulting in communication speed decrease, noise, or inability to connect, if Bluetooth communications are used near a wireless LAN device. In such cases, take the following measures.
- 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 lags slightly behind the sound of the sending device.
- Radio waves emitted from a Bluetooth device may affect the operation of equipment such as electronic medical devices. Turn off your Walkman and other Bluetooth devices 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 that occur 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 be established.
