Note

The RF Gain is used to optimize reception in weak signal areas. .

The RF noise blanker is very effective in reducing repetitive noises such as ignition interfer- ence.

1When switched toManual background ANL the Automatic Noise Limiter is activated. This helps reduce noise created by the vehicle’s electronics.

When switched to Manual backgroundNB/ANL position the RF Noise Blanker is also activated, providing increased noise filtration.

When switched to Manual background OFF position all noise filtration will be turned off.

1Rotate the Manual background RF Gain knob counterclockwise to reduce gain in strong signal areas. In weak signal areas turn clockwise to increase gain.
