Additional Information
The sensitivity of the Bluetooth 
communication will improve by 
turning the direction of the built-in 
aerial to the connected Bluetooth 
device. 
The communication distance shortens 
when the obstacles are between the 
aerial of the connected device and this 
product.
 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 this product.
 Because Bluetooth devices and wireless 
LAN (IEEE802.11 b/g) use the same 
frequency, microwave interference may 
occur and resulting in communication 
speed deterioration, noise, or invalid 
connection if this product is used near 
a wireless LAN device. In such a case, 
perform the following.
– Install this product and Bluetooth 
device as near to each other as possible.
– If this product is used within about  
10 meters (about 30 feet) of a wireless 
LAN device, turn off the wireless 
LAN device.
 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
