Once Bluetooth devices are paired, the unit memorizes these devices even after 

disconnection the device. 

There is no need for pairing again to listen to music.

*

The unit can only pair with one device at a time. To pair with multiple devices, each 

device needs to be paired individually.

*Pairing will be necessary again in the following cases.

  If pairing information is deleted after repair, etc.

  The unit can be paired with up to 9 devices. If a new device is paired after 9 devices 

have been paired, the device whose latest connection time is the oldest among the 9 

paired devices is replaced by the new one.

  If the pairing information of the unit is deleted on the Bluetooth device.

  If the unit is initialized.

Pairing the unit with Bluetooth devices

The following operations are required when connecting the unit to Bluetooth devices via

About Bluetooth wireless technology

Bluetooth wireless technology is a short-range wireless technology that enables wireless 

data communication between digital devices, such as compact stereos or digital music 

players. Connecting two devices as needed is the typical method, but simultaneous 

connection of multiple devices is also possible.

You do not need to use a cable for connection since Bluetooth technology is a wireless 

technology, 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 technology is an international standard employed and supported by thousands 

of companies worldwide.

Compatible Bluetooth profiles

Bluetooth profiles are standardized according to the purpose of the Bluetooth device. 

This product supports the Bluetooth version and profiles shown below. 

Compatible Bluetooth version:

Bluetooth specification version 2.1+EDR *

Compatible Bluetooth profiles

-A2DP 1.0 (Advanced Audio Distribution Profile): You can send and receive high quality music 

content.

-AVRCP1.3 (Audio Video Remote Control Profile): You can adjust the volume of the unit via a 

supported Bluetooth device.

*EDR stands for Enhanced Data Rate.

Communication range

Operates Bluetooth wireless technology within a range of about 10 meters. The actual 

range will vary under the following circumstances.

- Communication is obstructed (metal, walls, people, etc.).

- Communication is via the wireless LAN function.

- There are magnetic fields, such as from a microwave oven or other electromagnetic devices.

Interference from other devices

Because Bluetooth devices and wireless LAN (IEEE802.11b/g) use the same frequency 

(2.4 GHz frequency), microwave interference may occur, resulting in reduced 

communication speed, 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 10m away from the wireless LAN device.

– If the unit is used within 10m of a wireless LAN device, turn off the wireless LAN device.

Interference from other devices

Microwaves emitting from a Bluetooth device may affect the operation of electronic 

medical devices. Turn off your unit and other Bluetooth devices in the following 

locations, as it may cause an accident.

-where inflammable gas is present

-in a hospital

-in a train or airplane

-at a petrol station

-near automatic doors

-near a fire alarm

Note

 To use the Bluetooth function of the unit, check that the Bluetooth device supports the same profiles 

as your unit does. Even if the connected device supports the same Bluetooth profile, some devices 

may not be connected or work correctly, depending on the features or specifications of the device.

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

is slightly delayed from the sound played on the unit.

 Your unit supports security capabilities that comply with the Bluetooth standard to provide a secure 

connection when 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 leakage of information during Bluetooth communication.

 A Bluetooth device 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.

 There might be noise, or the sound might skip depending on the usage environment, certain 

communication conditions, or the connected Bluetooth device.
