Radio, Stereo, and Compact Disc: Testing and Inspection

Audio System

Inspection And Verification

1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical or electrical damage.

NOTE: Before any testing of the 'audio sound quality' make sure that the cassette tape mechanism is cleaned using the Jaguar cleaning tape. Any testing material (tape, CD, radio, mini disc) should be of known 'good quality'. Avoid using tapes that are old, home recordings, or damaged. Avoid using compact discs that are scratched, dirty, CDR's or CDRW's. Avoid using radio stations that are in the AM band, weak signal strength, inside buildings or poor reception areas. Use a good sound source for testing.

1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.

2. NOTE: If a new audio unit is being installed under warranty, please supply the digital data bus (D2B) ring configuration and the diagnostic trouble code(s) with the returned unit to aid fault replication.

If the cause is not visually evident, verify the symptom and refer to the Jaguar approved diagnostic system.
