Precautions
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 (person, metal, wall, etc.) or electromagnetic environment.
•The aerial of this unit is built into the right unit as illustrated in the dotted line. The sensitivity of Bluetooth communication will improve by placing a connected Bluetooth device on your right side.
The communication distance shortens when the obstacles are between the aerial of the connected device and this unit.
Location of
•The following conditions may affect the sensitivity of Bluetooth communication.
–There is an obstacle such as a person, 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
22 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, 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.
