CAUSES OF NOISE
When the radio receives a signal from a station, there may be some noise interference. The cause could be
1. Defective audio system.
2. The vehicle itself inducts noise (called outside noise).
3. Noise from other cars or neon signs, for example, ambience noise.
Since ambience noise is a temporary occurrence, this section does not deal with it. For noise problems,
first, the cause of the noise must be determined through the troubleshooting guide. Once it has been deter-
mined, refer to the suppression chart to find the proper procedure for eliminating the noise.
FM STATION
93u15x-07 1 03UOTX-187
FM multipath
FM waves can cause a problem called multipath receiving.
This happens when the radio picks up a direct wave and
reflected wave at the same time. This results in a “Dead Spot”
or distorted sound.
