221Chapter 6 Audio SystemSection 1 Audio System DescriptionDescription:
1. Radio Wave Band
The radio wave bands used in radio broadcasting are as following:
LF: Low frequency
MF: Medium frequency
HF: High frequency
VHF: Very High frequency
2. Cover Area
There are great differences in the size of the
cover area for AM and FM monaural. Some-
times FM stereo broadcasts cannot be received
even though AM comes in very clearly. Not only
does FM stereo have the smallest cover area,
but it also picks up static and other types of in-
terference ("noise") easily.
3. Reception problems
Hint:
Besides the static noise fault, there are also the faults called "interference", "multipath transfer" and "fade
out". These faults are caused not by electrical noise but by the nature of the radio waves themselves.
(1) Interference
Besides static noise fault, AM broadcasts are
also susceptible to other types of noises, es-
pecially at night. This is because AM radio
waves are reflected by the Ionosphere at
night. These radio waves then interfere with
the signals from the same transmitter that
reach the vehicle's antenna directly. This type
of noise is called "interference".BandLF MF HF VHF

238Section 4 Audio and Video System ReplacementI. Notice on operationPlease explain to the customer that the AM/FM broadcast channel information will be cleared when remov-
ing the battery negative terminal cable. Record the channel information before removing the negative termi-
nal cable if necessary. Reset after connecting the negative terminal cable.
yAll cassette tapes and CDs must be taken out before radio removal and installation.
yIf the cassette tapes and CDs can not be taken out due to radio fault. Do not take them out by force.
Drive the vehicle to Service Station.
yMake sure the grounding bolts are tightened before antenna removal and installation.
yThere will be noise when receiving electric wave if the grounding bolts are not tightened.
yDon't touch the speaker cone.Intermediate Multiple CD main unit Radio assemblyInstrument PanelMultiple DVD main unit
