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

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.
