A-5There is more noise either on AM or on FM.1. There is much noise
onlv on AM
Due to differences in AM and FM systems, AM
is more susceptible to noise interference.Were conditions such as the following present when noise was received?
l Lightning was flashing. A motorcycle was passing.
l
Avehicle passed close by, but it appeared to be avehicle generating a particularlylarge amount of noise radiation.
l Passed beneath a power line. Passed under a bridge.
l Passed beneath a telephone line.
l Passed close by a signal generator.
l Passed close by some other source of electrical noise.

If the problem is particularly worse than
other radios, consult a service center.
2. There is much noise only on FM
Due to differences in FM and AM systems, FM
is not as susceptible as AM to interference from
engines, power lines, lightning, etc. On the other
hand, there are cases due to the characteristicsof FM waves of noise or distortion generated
by typical noise interference (first fading and
multipath). (Refer to A-2)
curs in weak signal areas such as mountainous
regions, but this is not due to a problem with
the radio.>

YesStatic electricity noise:
Body static electric from the shock absorber rubber bushings used
to prevent vibration, tires, etc. occurs because of separation fromthe ground, causing a buzzing noise.

About multipath noise and fading noise
Because the frequency of FM waves is extreme-
ly high, it is highly susceptible to effects from
geological formations and buildings. These ef-
fects disrupt the broadcast signal and obstruct
‘reception in several ways.l Multipath noise
This describes the echo that occurs when the
broadcast signal is reflected by a large obstruc-
tion and enters the receiver with a slight time
delay relative to the direct signal (repetitious
buzzing).l Fading noise
This is a buzzing noise that occurs when the
broadcast beam is disrupted by obstructing ob-
jects and the signal strength fluctuates intricately
within a narrow range.

THE PRINTED-HEATER LINES CHECK
(1) Run engine at 2,000 rpm. Check heater element with bat-tery at full.
(2) Turn ON rear window defogger switch. Measure heater
element voltage with circuit tester at rear window glass
center A.
Condition good if indicating about 6 V.
(3) If 12 V is indicated at A, there is a break in the negative
terminals from A.
Move test bar slowly to negative terminal to detect where
voltage changes suddenly (0 V).(4) If 0 V is indicated at A, there is a break in the positive
terminals from A. Detect where the voltage changes sud-
denly (12 V) with the same method described.
THE PRINTED-HEATER LINES REPAIR
REQUIRED MATERIALSl Thinner
l Tapel Lead-free gasoline
l Fine brush
l Conductive paint
(1) Clean disconnected area with lead-free gasoline. Tape
along both sides of heater element.
(2) Mix conductive paint thoroughly. Thin the required amount
of paint in a separate container with a small amount of
thinner and paint break three times at 15 minute intervals.(3) Remove tape and leave for a while before use (circuit
complete).
(4) When completely dry (after 24 hours) finish exterior with
a knife.
Caution
Clean glass with a soft cloth (dry or damp) along defog-
ger heater element.REAR WINDOW DEFOGGER SWITCH
(1)Remove rear window defogger switch from the meter bezel.(Refer to
P.54-109.)
(2) Operate the switch and check the continuity between the
terminals.
