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 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.
