Program audio ducking level in talk over mode
Adjust audio ducking level	X1@ * 58#	Adl X1@ ]	Adjusts how much
			(X1@ = 0 to 30 dB) the program
			audio ducks (automatically
			decreases) in talk over mode.
			0 = ducking off.
Increment audio ducking	+*58#	Adl X1@ ]
Decrement audio ducking	–*58#	Adl X1@ ]
View audio ducking level	58#	X1@ ]
Volume level
Specify volume variable	X1) V/v	Vol X1) ]	Volume level is X1).
			X1) = 000 – 100 (program	X
			volume adjustment range).
Increment volume	+V	Vol X1) ]	Volume level is X1).
Decrement volume	–V	Vol X1) ]	Volume level is X1).
View volume	V	X1) ]	Volume level is X1).
Audio mute	X# Z/z	Amt X# ]	X#: 0 = off and 1 = on.	X
View audio mute status	Z/z	X# ]	Mute status is (0=off, 1=on).
Mic level
Specify gain	16* X$ G	Aud X$ ]	X$ = audio gain in dB = 0 to
			12. This variable is a positive	X
			number.
Specify attenuation	16*X% g	Aud X% ]	X% = attenuation in dB = 1 to
			66. This variable is a positive
			number.
View mic volume	16G/g	X^ ]	X^ = overall mic gain or
			attenuation between -66 dB
			and +12 dB. This response
			variable indicates attenuation as
			a negative number and gain as
			a positive number.
Mic mute on/off
Turn mic mute on/off	X# M/m	Mix X# ]	Toggles mic mute on or off.	X
			X#: 0 = off, 1 = on.
View mic mute status	M/m	X# ]	Mic mute status: (0=off, 1=on).
Mic talk-over threshold
Display talk-over threshold	X* * 2 #	Thr X* ]	Shows the mic threshold
			number. X* = 0 through 15,
			default = 8.
Decrement threshold	– * 2#	Thr X* ]	Decrements mic threshold one
			step.
Increment threshold	+ * 2#	Thr X* ]	Increments mic threshold one
			step.
