STEP 2. Check the location of the distortion.
Q: Is there distortion when the vehicle is near the radio station?
YES: The antenna is receiving too strong a signal.
NO: Go to Step 3.
STEP 3. Check the wires at each speaker.
Q: Are the speaker wires contacting the paper speaker cone?
YES: Move the speaker wires away from the paper speaker cone. The speaker should now be free of distortion.
NO: Go to Step 4.
STEP 4. Remove the speakers, and check the paper cone for foreign material or damage.
Q: Is there foreign material or damage on the paper cone of the speaker?
YES: Repair or replace the speakers. The speaker should now be free of distortion.

Inspection Procedure 20
Distortion on FM Only.
DIAGNOSIS
STEP 1. Check that the distortion is present when the radio is tuned to another station.
Q: Does the distortion persist when the radio is tuned to another station?
YES: Go to Step 2.
NO: The signal from that station is too weak.
STEP 2. Relocate the reception area and check the radio.
Q: When relocating the reception area does the distortion increase or decrease?
YES: The cause may be multipath or fading noise. Multipath noise is the echo that occurs when the broadcast signal is reflected by a large obstruction
and enters the receiver with a slight time delay relative to the direct signal (repetitious buzzing). A fading or buzzing noise may occur when the
broadcast beam is disrupted by obstructing objects and the signal strength fluctuates within a narrow range.
NO: Replace the radio and CD player or radio, CD player and CD changer. Check that a distortion is resolved.
