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 unit and BLUETOOTH device.
• A wireless LAN device is in use near the unit.
• A microwave oven is in use near the unit.
• A device that generates electromagnetic radiation is in use near the unit.
• The unit is placed on a shelf made of steel.

Interference from other devices

Because BLUETOOTH devices and wireless LAN (IEEE802.11b/g/n) use the same frequency, microwave interference may occur and resulting in communication speed deterioration, noise, or invalid connection if the unit is used near a wireless LAN device. In such a case, perform the following.

• Use the unit at least 10 m (33 feet) away from the wireless LAN device.
• If the unit is used within 10 m (33 feet) of a wireless LAN device, turn off the wireless LAN device.
• Use the BLUETOOTH device as close to the unit as possible.

Interference to other devices

Microwaves emitting from a BLUETOOTH device may affect the operation of electronic medical devices. Turn off the 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 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 unit'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 unit is slightly delayed from the sound played on the BLUETOOTH device during listening to the music.
• 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.
• 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.
• Noise or sound skips may occur depending on the BLUETOOTH device connected with the unit, the communication environment or the usage environment.
