Adjust Audio AGC

Configure how the scanner handles the Automatic Gain Control (AGC) for Analog and Digital signals:

Parameter	Definition	Analog settings	Digital settings

Response Time	How frequently	-4 to +6	-8 to +8
	the AGC factor	(default=0)	(default=0)
	updates. Decrease
	this value to make
	AGC respond
	faster (but this
	could result in
	pumping). Increase
	this value to make
	AGC respond
	more slowly.
Reference Gain	The reference level	-5 to +5	-5 to +5
	that AGC attempts	(default=0)	(default=0)
	to adjust the
	volume to. If
	digital and analog
	volumes don't
	match, adjust this
	parameter.
Gain Range	The total dynamic	0 to 15	NA
	range of the AGC
	adjustments. A
	larger value allows
	a wider variation
	in volume.

Adjust Contrast

Select one of the 15 available contrast levels for the display. As you scroll through the options, the display adjusts to the highlighted contrast level; press YES when you see the display contrast you want to use.
