Auto - the scanner uses the default modulation for

the frequency band.

AM - the scanner uses AM (amplitude modulation) for

the frequency band.

FM - the scanner uses FM (frequency modulation) for

the frequency band.

NFM - the scanner uses narrowband FM for the

frequency band.

WFM - the scanner uses wideband FM for the

frequency band.

Note: The default setting is Auto.

This setting controls the modulation method used for
the frequency band. In most cases, if you leave this
set to Auto, the scanner automatically selects the

correct modulation type for the system you are

programming.
