USING THE ATTENUATOR

To reduce interference or noise caused by strong sig- nals, you can reduce the scanner’s sensitivity to these signals. Press ATT until A appears to reduce the scan- ner’s sensitivity on the current channel.

Note: If you turn on this feature, the scanner might not receive weak signals.

To turn off the attenuator, press ATT again. A disap- pears.

This setting is stored for each channel.
