Yamaha and the Electronic Industries Association’s Consumer Electronics Group want you to get the most out of your 
equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or 
distortion - and, most importantly, without affecting your sensitive hearing. Since hearing damage from loud sounds is 
often undetectable until it is too late, Yamaha and the Electronic Industries Association’s Consumer Electronics Group 
recommend you to avoid prolonged exposure from excessive volume levels. Operate this unit by the following 
procedure.

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).

NOTICE
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These 
limits are designed to 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 unit features a magnetically shielded design, but there is still a chance that placing it too close to a TV set might impair picture color. 
Should this happen, move this unit away from the TV set.

FOR CANADIAN CUSTOMERS
This Class B digital apparatus complies with Canadian ICES-003.

FCC WARNING
Change or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the
