Bluetooth Wireless Technology
Bluetooth wireless technology is a short-range wireless technology linking digital devices,
such as personal computers and digital still cameras. Using the Bluetooth wireless
technology, you can operate the units involved within a range of about 10 meters (30 feet).
The Bluetooth wireless technology is commonly used between two devices, but a single
device can be connected to multiple devices. You do not need wires to get connected as you
do with a USB connection, and you do not need to place the devices face to face as you do
with wireless infrared technology. You can use the technology with one Bluetooth device in
your bag or pocket.
Bluetooth wireless technology is a global standard supported by thousands of companies.
These companies produce products that meet the global standard.
Supported Bluetooth version and profiles
Profile refers to a standard set of capabilities for various Bluetooth product capabilities. This
system supports the following Bluetooth version and profiles.
Supported Bluetooth version: Bluetooth Standard version 2.0
Supported Bluetooth profiles:
A2DP (Advanced Audio Distribution Profile)
AVRCP (Audio Video Remote Control Profile)
SPP (Serial Port Profile)
Effective communication range
Bluetooth devices should be used within approximately 10 meters (30 feet) (unobstructed
distance) of each other.
The effective communication range may become shorter under the following conditions.
When a person, metal object, wall or other obstruction is between the devices with a Bluetooth
connection
Locations where a wireless LAN is installed
Around microwave ovens that are in use
Locations where other electromagnetic waves occur
Effects of other devices
Bluetooth devices and wireless LAN (IEEE 802.11b/g) use the same frequency band (2.4 GHz).
When using your Bluetooth device near a device with wireless LAN capability, electromagnetic
interference may occur. This could result in lower data transfer rates, noise, or inability to
connect. If this happens, try the following remedies:
Try connecting this player and a Bluetooth device when you are at least 10 meters (30 feet) away
from the wireless LAN equipment.
Turn off the power to the wireless LAN equipment when using your Bluetooth device within 10
meters (30 feet).
Effects on other devices
The radio waves broadcast by this system may interfere with the operation of some medical
devices. Since this interference may result in malfunction, always turn off the power on this
player and a Bluetooth device in the following locations:
In hospitals, on trains, in airplanes, at gas stations, and any place where flammable gasses may
be present
Near automatic doors or fire alarms
Notes
This player supports security functions that comply with the Bluetooth specification as a means
of ensuring security during communication using Bluetooth technology. However, this security
may be insufficient depending on the setting contents and other factors, so always be careful
when performing communication using Bluetooth technology.
Sony cannot be held liable in any way for damages or other loss resulting from information
leaks during communication using Bluetooth technology.
