 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 Bluetooth antenna (aerial) is built into the player ( page 10). The 

sensitivity of Bluetooth communication will improve by turning the direction 

of the built-in Bluetooth antenna (aerial) to the connected Bluetooth device. 

The communication distance shortens when the obstacles are between the 

connected device and the player.



 The following conditions may cause noise, sound break or playback speed 

change.

 When using inside the metal bag.

 When using inside the backpack or shoulder bag.

  A device using 2.4 GHz frequency, such as a wireless LAN device, cordless 

telephone, or microwave oven, is in use near the player or the device.



 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 Bluetooth 

communication is performed near a wireless LAN device. In such a case, 

perform the following.

  Perform Bluetooth communication at least 10 meters (about 30 feet) away 

from the wireless LAN device.

  Install the player and Bluetooth device as near to each other as possible.

  When performing Bluetooth communication within about 10 meters (about 

30 feet) of a wireless LAN device, turn off the wireless LAN device first.



 Due to the characteristic of Bluetooth wireless technology, the sound played on 

the Bluetooth device is slightly delayed from the sound played on the player.



 Microwaves emitting from a Bluetooth device may affect the operation of 

electronic medical devices. Turn off the player and other Bluetooth device 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.
