TROUBLESHOOTING
Be sure to investigate thoroughly before requesting repairs or after service. If it cannot be corrected, or if the problem is not
listed in the SYMPTOM column, disconnect the power cord and contact your authorized YAMAHA dealer or service center.
Notes
• Sometimes the system may cease to recognize operations due to a mistaken 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, be sure to bring along with the VS-10 (sold separately).
