Setting Modulation Menu Program System Select the system 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. Setting Attenuation Menu Program System Select the system Set Attenuator This setting controls whether the attenuator will be on or off for the current system. Select your setting then press the scroll control. Off - the attenuator is off. On - system frequencies are attenuated by about 18 dB. Notes: • Even if ATT appears, attenuation might not work if the bar antenna is turned on and the tuned frequency is from 0.1 to 1.7 MHz. • Turn on this setting if you are near strong signal sources. Attenuation can help reduce interference and desensitization that strong signals create. Programming Radio Systems 71

This setting controls whether the attenuator will be on

- system frequencies are attenuated by about 18

Notes:
•
Even if

the bar antenna is turned on and the tuned
frequency is from 0.1 to 1.7 MHz.
•
Turn on this setting if you are near strong signal
sources. Attenuation can help reduce interference
and desensitization that strong signals create.
