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.
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.

Communication System and Compatible BLUETOOTH Profiles of 
the system

Profile is standardisation of the function for each BLUETOOTH device specification. 
The system supports the following BLUETOOTH version and profiles:
Communication System:
BLUETOOTH Specification version 3.0

A wireless LAN device is in use near the system.

ˎ

ˋ

A microwave oven is in use near the system.

ˎ

ˋ

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.

ˎ

ˋ

Use the system at least 10 m away from the wireless LAN device.

ˎ

ˋ

If the system is used within 10 m of a wireless LAN device, turn off the 
wireless LAN device.

the following locations, as it may cause an accident.

ˎ

ˋ

where inflammable gas is present, in a hospital, train, airplane, or a gas 
station

ˎ

ˋ

near automatic doors or a fire alarm

Notes

ˎ

ˎ

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.

ˎ

ˎ

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.

ˎ

ˎ

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.

ˎ

ˎ

We do not take any responsibility for the leakage of information during 
BLUETOOTH communication.

ˎ

ˎ

A device featuring the BLUETOOTH function is required to conform to the 
BLUETOOTH standard specified by Bluetooth SIG, and be authenticated. 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.

ˎ
