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.
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

capabilities for various Bluetooth product
capabilities. This system supports the
following Bluetooth version and profiles.

Effective communication range
Bluetooth devices should be used within
approximately 10 meters (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 system and
Bluetooth mobile phone or Bluetooth
device when you are at least 10
meters away from the wireless LAN
equipment.
 Turn off the power to the wireless LAN
equipment when using your Bluetooth
device within 10 meters.
