INSPECTION PROCEDURE 13: Ever-Present Noise.: Diagnosis

Noise is often created by the following factors, and often the radio is OK when it is checked individually.

• Traveling conditions of the vehicle
• Terrain of area traveled through
• Surrounding buildings
• Signal conditions
• Time period

For this reason, if there are still problems with noise even after the measures described in inspection procedure 7 to 14 have been taken, get information on the factors listed above as well as determining whether the problem occurs with AM or FM, the station names, frequencies, etc. and contact the radio manufacturer's service center.
