Troubleshooting

No sound / Sound from only one speaker /

Low sound level

Check that both this system and

the connected device are turned

on.

If you are connecting a personal

computer to the system, make

sure the audio output setting of

the computer is set for a Bluetooth

device.

Turn up the volume of the system

and the connected device.

Pair this system and the Bluetooth

device again.

Check that the connected device

is being played back.

If the connected device is monaural,

sound will only be output from the

left speaker.

Check that both plugs of the

connecting cord (supplied) are

firmly inserted into the system

and the connected device.

Distorted sound /

Humming or noise in the system output

Turn down the volume of the

connected device.

Keep the system away from a TV.

If the connected device has an

equalizer function, set it to off.

If the POWER indicator (green) is

flashing, replace all the batteries

with new ones.

Keep the system away from a

microwave oven, wireless LAN,

etc.

If you connect a device with a built-

in radio or tuner to this system,

broadcasts may not be received, or

sensitivity may be reduced. Locate

the system farther away from the

device and check that you can listen

to the broadcasts satisfactorily.

Bring this system and the

Bluetooth device closer together.

Remove any obstacle between

this system and the Bluetooth

device.

Pairing is not possible

Bring this system and the

Bluetooth device to within 1 m

(3 ft) of each other.

Make sure pairing mode of the

system is activated.

What is Bluetooth wireless

technology?

Bluetooth wireless technology is a short-range wireless

technology that enables wireless data communication between

digital devices, such as a computer and digital camera. Bluetooth

wireless technology operates within a range of about 10 m

(about 30 ft).

Connecting two devices as necessary is common, but some

devices can be connected to multiple devices at the same time.

You do not need to use a cable for connection, 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 standard is an international standard supported by

thousands of companies all over the world, and employed by

various companies worldwide.

Communication System and Compatible

Bluetooth Profiles of the system

Profile is standardisation of the function for each Bluetooth

device specification. The system supports the following

Bluetooth version and profiles:

Communication System:

Bluetooth Specification version 3.0

Compatible Bluetooth Profiles:

A2DP (Advanced Audio Distribution Profile): Transmitting or

receiving audio content of high-quality.

AVRCP (Audio Video Remote Control Profile): Controlling the

sound volume.

Maximum communication range

Use Bluetooth devices within 10 m (about 30 ft) (line of sight) of

the system.

Maximum communication range may shorten under the

following conditions.

There is an obstacle such as a person, metal, or wall between

the system and Bluetooth device.

A wireless LAN device is in use near the system.

A microwave oven is in use near the system.

A device that generates electromagnetic radiation is in use

near the system.

Interference from other devices

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 the system is used near a wireless LAN device. In

such a case, perform the following.

Use the system at least 10 m (about 30 ft) away from the

wireless LAN device.

If the system is used within 10 m (about 30 ft) of a wireless

LAN device, turn off the wireless LAN device.

Interference to other devices

Microwaves emitting from a Bluetooth device may affect the

operation of electronic medical devices. Turn off the system 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 gas station

near automatic doors or a fire alarm

Notes

 To be able to use the Bluetooth function, the Bluetooth device

to be connected requires the same profile as the system’s.

Note also that even if the same profile exists, devices may vary

in function depending on their specifications.

 Due to the characteristic of Bluetooth wireless technology, the

sound played on the system is slightly delayed from the sound

played on the Bluetooth device during talking on the

telephone or listening to the music.

 This system supports security capabilities that comply with

the Bluetooth standard to provide a secure connection when

the 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 the leakage of

information during Bluetooth communication.

 A device featuring the Bluetooth function 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.

 Noise or sound skips may occur depending on the Bluetooth

device connected with the system, the communication

environment or the usage environment.
