On Bluetooth communication



 Bluetooth wireless technology operates 

within a range of about 10 meters (about 

30 feet). 

Maximum communication range may vary 

depending on obstacles (human body, 

metal, wall, etc.) or electromagnetic 

environment.



 The antenna is built into the unit as 

illustrated in the dotted line. The 

sensitivity of the Bluetooth communication 

will improve by turning the direction of 

the built-in antenna to the connected 

Bluetooth device. 

The communication distance shortens 

when the obstacles are between the 

antenna of the connected device and this 

unit.



 The following conditions may affect the 

sensitivity of Bluetooth communication.

–  There is an obstacle such as a human 

body, metal, or wall between this unit 

and Bluetooth device.

–  A device using 2.4 GHz frequency, such 

as a wireless LAN device, cordless 

telephone, or microwave oven, is in use 

near this unit.



 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 this unit is used near a 

wireless LAN device. In such as case, 

perform the following.

–  Use this unit at least 10 m (about 30 ft) 

away from the wireless LAN device.

–  If this unit is used within 10 m (about 

30 ft) of a wireless LAN device, turn off 

the wireless LAN device.

–  Install this unit and Bluetooth device as 

near to each other as possible.



 Microwaves emitting from a 

Bluetooth 

device may affect the operation of 

electronic medical devices. Turn off this 

unit 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 petrol 

station

–  near automatic doors or a fire alarm



 This unit 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.



 We do not take any responsibility for the 

leakage of information during Bluetooth 

communication.



 Connection with all 

Bluetooth devices 

cannot be guaranteed.

–  A device featuring Bluetooth function is 

required to conform to the Bluetooth 

standard specified by Bluetooth SIG, 

Inc. 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.

–  While talking on the phone hands free, 

noise may occur, depending on the 

device or communication environment.



 Depending on the device to be connected, 

it may require some time to start 

communication.
