What is 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 (about 30 ft).
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.
Maximum communication range
Maximum communication range may shorten under the following conditions.
There is an obstacle such as a person, metal, or wall between the system and
BLUETOOTH device.
A wireless LAN device is in use near the system.
A microwave oven is in use near the system.
A device that generates electromagnetic radiation is in use near the system.
Interference from other devices
Because BLUETOOTH devices and wireless LAN (IEEE802.11b/g) use the same frequency,
microwave interference may occur and resulting in communication speed deterioration,
noise, or invalid connection if the system is used near a wireless LAN device. In such a
case, perform the following.
Use the system at least 10 m (about 30 ft) away from the wireless LAN device.
If the system is used within 10 m (about 30 ft) of a wireless LAN device, turn off the
wireless LAN device.
Interference to other devices
Microwaves emitting from a BLUETOOTH device may affect the operation of electronic
medical devices. Turn off the system and other BLUETOOTH devices in the following
locations, as it may cause an accident.
where inflammable gas is present, in a hospital, train, airplane, or a gas station
near automatic doors or a fire alarm
Notes
To be able to use the BLUETOOTH function, the BLUETOOTH device to be connected
requires the same profile as the system’s.
Note also that even if the same profile exists, devices may vary in function depending on
their specifications.
Due to the characteristic of BLUETOOTH wireless technology, the sound played on the
system is slightly delayed from the sound played on the BLUETOOTH device during
talking on the telephone or listening to the music.
This system supports security capabilities that comply with the BLUETOOTH standard
to provide a secure connection when the BLUETOOTH wireless technology is used, but
security may not be enough depending on the setting. Be careful when communicating
using BLUETOOTH wireless technology.
