Hold on the channel you would like the attenuation and push the function 'F' key and then the number 4. Make sure the letter F is in the upper left hand corner and don't press both buttons at the same time. If you would like global attenuation, push and hold the number 4 for three seconds.I can't figure out how to turn on the Att.per single frequency.
Read the online Manual and I press "Chan" to hold the Channel/frequency press Function Key and after that the # 4 Key and nothing.
What I'm missing ?
Try this. While scanning, push the white button labeled 'CHAN' and then move the top 'scroll control' (sel/vol/sq) to the channel you would like the attenuation on. Next push the top button on the left side of the scanner and the 'F' will appear on the top left of the screen. Then press the number 4. The display should read "attenuation on". I just tried it on mine and it worked.I can turn global Att on from the Screen but when I just press #4 I get an :Error" Beep and nothing happens.
I had no idea it wouldn't work using the full database. Thanks for letting me know. I will add that to my notes.When I only Scan my Favorite List I can turn Att on.
When I scan with Full database it does not work even the way you described
