provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful interference to
radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
This equipment compiles with FCC/IC radiation exposure limits set forth for uncontrolled
equipment and meets the FCC radio frequency (RF) Exposure Guidelines in Supplement C
to OET65 and RSS-102 of the IC radio frequency (RF) Exposure rules. This equipment has
very low levels of RF energy that it deemed to comply without maximum permissive
exposure evaluation (MPE). But it is desirable that it should be installed and operated with at
least 20 cm and more between the radiator and person’s body (excluding extremities: hands,
wrists, feet and ankles).
This transmitter must not be co-located or operated in conjunction with any other antenna or
transmitter.

Bluetooth
Bluetooth is a technology for wireless communication between devices within an
area of about 10 meters (33 ft) employing the 2.4 GHz frequency band, a band
which can be used without a license.
Bluetooth is a registered trademark of the Bluetooth SIG and is used by Yamaha in
accordance with a license agreement.
Handling Bluetooth communications
The 2.4 GHz band used by Bluetooth compatible devices is a radio band shared by
many types of equipment.
While Bluetooth compatible devices use a technology minimizing the influence of
other components using the same radio band, such influence may reduce the speed
or distance of communications and in some cases interrupt communications.
The speed of signal transfer and the distance at which communication is possible
differs according to the distance between the communicating devices, the presence
of obstacles, radio wave conditions and the type of equipment.
Yamaha does not guarantee all wireless connections between this unit and devices
compatible with Bluetooth function.

Precautions
Please read the following operating precautions before use:
Use the AC adaptor designed specifically for this unit only. Yamaha is not
responsible for damage caused by using other power adaptors.
Do not apply pressure or force the control knobs of this unit, or place heavy items
on the cabinet.
Avoid outputting from test disks, electrical musical instruments, or from
extremely loud or distorted input. It may cause a malfunction of the speakers.
This unit may cause picture distortion when placed close to a computer monitor
or television. In this case, move the unit away from them.
Keep this unit away from magnetic media such as floppy disks and tapes.
Otherwise the data on the media may become corrupted.
Remove the AC adaptor from the wall outlet immediately if any problem is
found.

1 Headphones connector (3.5 mm stereo mini jack)
Use for a headphones connection.
When headphones are connected, sound is not output through the speakers.
To protect your hearing, make sure that the volume is low before headphones are
used.
Do not use headphones with a loud volume for a long time. Otherwise, your
hearing may be damaged.
Make sure that the volume of the audio devices is at minimum before
headphones are connected. A sudden loud sound may damage your hearing.
2 VOL (volume) control
Controls the volume of the speakers and the headphones.
The volume becomes louder as the VOL (volume) control is rotated to
the right, and quieter as it is rotated to the left.
The Loudness control function of the speakers allows you to enjoy rich
bass tone sounds even at low volumes.
The function automatically corrects for optimum sound, depending on
the units output level.
Adjust the output sound level as follows;
a After you connect an external device to this unit, turn on the power of this unit
and then rotate the
VOL
(volume) control to the 2 oclock position (see the
illustration below).
b Adjust the volume of the external device to the loudest level
before the onset of distortion.

Nous vous souhaitons un plaisir musical durable
Yamaha et le Groupe des Entreprises Électroniques Grand Public de
l’Association des Industries Électroniques vous demandent de tirer le
meilleur parti de votre équipement tout en écoutant à un niveau non
dommageable pour l’ouïe, c’est-à-dire un niveau où vous pouvez obtenir
un son fort et clair, sans hurlement ni distorsion, mais sans aucun danger
pour l’ouïe. Comme les sons trop forts causent des lésions auditives qui ne peuvent être
détectées qu’à long terme, lorsqu’il est trop tard, Yamaha et le Groupe des Entreprises
Électroniques Grand Public de l’Association des Industries Électroniques vous
déconseillent l’écoute prolongée à des volumes excessifs.
