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

1 When switched to

ANL the Automatic Noise

Limiter is activated. This helps reduce noise

created by the vehicle’s electronics.

When switched to

NB/ANL position the RF

Noise Blanker is also activated, providing

increased noise filtration.

1When set in HI the treble is increased.

RF Gain Control

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

RF Gain Control

When switched to OFF position all noise

filtration will be turned off.
