Be sure to investigate the problem thoroughly before requesting repairs or after service. If the problem cannot be corrected or
if it is not listed in the SYMPTOM column, disconnect the power cord and contact your authorized YAMAHA dealer or
service center.
Notes
• Sometimes the unit may cease to recognize operations due to an error in operation or as a result of strong external noise (such as irregular
voltage due to shock of impact, excessive static electricity, or lightning strike). If this happens, first disconnect the power cord, wait about
30 seconds, re-connect the power cord, and try the desired operation again.
• When requesting repairs or after service of the subwoofer and rear speakers, be sure to bring along the front speaker unit.
