BLUETOOTH wireless
technology
BLUETOOTH wireless technology is a short-
range wireless technology that enables
wireless data communication between
digital devices, such as a computer and
digital camera. BLUETOOTH wireless
technology operates within a range of about
10 m.
Connecting two devices as necessary
is common, but some devices can be
connected to multiple devices at the same
time.
You do not need to use a cable for
connection, nor is it necessary for the
devices to face one another, such is the case
with infrared technology. For example, you
can use such a device in a bag or pocket.
BLUETOOTH standard is an international
standard supported by thousands of
companies all over the world, and employed
by various companies worldwide.
Supported BLUETOOTH version and profiles
Profile refers to a standard set of capabilities
for various BLUETOOTH product capabilities.
See “Specifications” (page 36) for details
on the supported BLUETOOTH version and
profiles.
Note
•
To use a BLUETOOTH device connected to this
system, the device must support the same profile
as this system. Note that the functions of the
BLUETOOTH device may be different depending
on the specifications of the device, even if it has
the same profile as this system.
•
Because of the properties of BLUETOOTH wireless
technology, playback on this system is slightly
delayed compared with audio playback on the
transmitting device.
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
Interference from other devices
BLUETOOTH devices and wireless LAN
(IEEE802.11b/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 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
Interference to 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 system and BLUETOOTH
device in the following locations:
– In hospitals, on trains, and in airplanes
– Near automatic doors or fire alarms
