IDENTIFICATION OF NOISE SOURCE




a. Identify the condition under which the noise occurs, and check the noise filter on the related part.

b. Reference:
- Make sure first that there is no noise from outside.
Failure to do so makes it difficult to detect the noise source and leads to misunderstanding.
- The noise should be removed in descending order of loudness.
- Setting the radio in a tuneless state makes it possible to notice the noises, which help to recognize the phenomena.
