Listening to Songs through Bluetooth Communication
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.
Th
e 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.
Th
e 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 de
vice 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.
I
nstall the player and Bluetooth device as near to each other as possible.
W
hen 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.
