Programming Your Scanner
Note: If you select Control Channel Only mode (see “Setting Control-Channel
Only (Motorola Systems Only)” on Page 81), you only need to enter the
frequency(s) that can be assigned as the control channel. Most frequency lists
usually indicate which of the frequencies are the control channel frequencies.
Otherwise, you must enter all of the frequencies.

Set Modulation
Auto — the scanner uses the default 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.
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.
Enable Attenuation if you are near strong signal sources. Attenuation can help
reduce interference and desensitization that strong signals create. You can also
turn this setting on or off by holding on a trunked system, then pressing + [7].
