REDUCING NOISE
Note: Operation instructions are for satisfy- ing FCC RF exposure requirements.
Because your CB is exceptionally quiet, any noise you hear is probably from an external source in your vehicle such as an alternator, another radio, or spark plugs.
The transceiver uses an ANL (Automatic Noise Limiter) circuit to reduce noise. How- ever, if possible, try to eliminate the noise by finding its source.
You can determine the noise’s source by turning off the engine and operating the CB with your vehicle’s ignition set to ACC (or ON). If the noise is reduced, the problem is in your vehicle’s ignition or electrical system.
Here are a few hints to help you reduce or eliminate such noise.
• Make all CB power and antenna wires as short as possible.
• Route the power wires away from the antenna wires.
• Be sure that the chassis ground connec- tion is secure.
• Replace old ignition wires with new,
• Install noise suppressors on your spark plugs, or install new spark plugs that have
• If problems persist, check your alterna- tor/generator and regulator gauges. You can reduce the noise from these sources by using bypass capacitors at the various output voltage points.
