NOISE SUPPRESSION
NOINQAC
1. Noise interfering with radio receptron may be roughly
classified as follows:
(1) Noise produced by the-vehicle itself
Noise from the rgnltionlcrrcurt, alternator: circuit, etc.
(2) Noise generated in the-radio itself
Thermal noise trom trarxx,tors, IC, resistor, etc.
(3) Atmospheric noise -
Noise from other cars,- neon signs, etc.
2. The radio has devices to suppress noise of the radio itself
and atmospheric norse, butit is difficult to elrmrnate them
completely. Noise produced by the vehicle in&d@ whin-
ing from the alternator system, and a strong, impulsive, fast
popping noise-from the @rtron system. --
PREVENTION OF IGNITION CIRCUIT NOISE
A resistance-equipped cable is used for the high-tension cab!e
in order to prevent noise; however, of any noise from the
ignition crrcurt does occur, check the trghtness~ and .ground
connectron of the terminal of tee noise suppression capacitor,
and, if necessary-check the norse suppression capacitor.
Caution
Be careful not to connect the noise filter to the high-
tension cable; doing so could damage the noise filter.

For other noises, take necessary corrective acrrons rn
accordance with the followrng items and the NOISE
SUPPRESlON~m CHART.
Polish the grounding cable termrnai, and connect it properly.
Polish the power antenna ground terminal,
and
connect!it
properly.
Ground electric parts completely.
Keep the antenna cable and speaker lead wire away from
other electric wiring.
