What would this option be that you mention?

Unfortunately, the manual does not clearly state the existence of noise reduction filters!

Does the ATS25 max decoder have a noise reduction function?

What is the purpose of the ATS ATT?

First of all, thank you for sending the digital manual.
When you click on the SCAN option, it scans and how do I take advantage of this search correctly?

I need forum support regarding the SCAN resource for a better understanding of this resource and its subdivisions FREQ, SNR and RSSI.
