REDUCING NOISE
The Automatic Noise Limiting (ANL) circuit helps keep background noise to a minimum. However, strong sources of electrical noise (such as your vehicle’s ignition, another radio, or spark plugs) might be more than the circuit can compensate for.
If you operate the
Here are a few hints to help you re- duce or eliminate such noise:
•Replace old ignition wires with new,
•Install noise suppressors on your spark plugs, or install new spark plugs that have
•Be sure that the ground connec- tion (black wire) is secure.
If problems persist, check your alter- nator/generator, regulator, and gaug- es. Noise from these sources can be reduced or eliminated using bypass capacitors at various output voltage points.
