AUDIO SYSTEM TROUBLESHOOTING:

DESCRIPTION

To simplify audio system troubleshooting, a flow chart (see next page) has been prepared. It contains essentials of audio system troubleshooting procedures, focusing on the following:

^ Obtain accurate information of customer's complaint.
^ Carry out appropriate diagnosis or troubleshooting to find the faulty part.
^ Avoid replacing unnecessary parts.
^ Verify whether the customer's complaint results from specific characteristics of FM radio waves. If so, the complaint cannot be corrected by audio component replacement.

Use the following materials with the attached flow chart when carrying out inspection and repair of the audio system.

^ Audio System Troubleshooting Procedures (plastic sheet)
^ Service Bulletin, Category 15, 050/87 (FM Reception)

NOTE:
If it becomes necessary to disconnect power to the audio system, be sure to copy down the customer's preset stations. Reset these stations after repairs are complete.
