The transceiver has 3 AGC characteristics (time con-
stant; fast, mid, slow) for non-FM/WFM mode.

q Select non-FM/WFM mode with [MODE].
w Select M-3.

•Push and hold [MENU/GRP] for 1 sec. once or twice

to select the menu group M.

•Push [MENU/GRP] momentarily one or more times to select the menu M-3.

e Push [F-3AGC] several times to select AGC fast,					[MENU/GRP] [F-3]
AGC medium (MID) AGC slow or AGC OFF.
•“	,” “	,” “	” or “	” appears when
	AGC fast, AGC medium (MID), AGC slow or AGC OFF
	is selected, respectively.
“	” (OFF) appears		when AGC time constant

OFF is set with one of FAST, MID, SLOW setting in AGC set mode.

DSetting the AGC time constant

q Select the desired mode other than FM/WFM modes.

w Select M-3.

•Push and hold [MENU/GRP] for 1 sec. once or twice

to select the menu group M.

•Push [MENU/GRP] momentarily one or more times to select the menu M-3.

e Push [F-3AGC] for 1 sec. to enter the AGC set mode.

r Push one of [F-2 FAST], [F-3 MID], [F-4 SLOW]

to select the desired AGC time constant.

t Rotate [DIAL] to set the desired time constant.

•AGC time constants can be selected between 0.1 to 8.0 sec. (depends on mode) or turned OFF.

•Push and hold [F-2FAST], [F-3MID] or [F-4SLOW] for 1 sec. to select a default value each for fast, mid. and slow, respectively.

y Select another mode other than FM/WFM. Repeat steps r and t, if desired.

•See table to the right for available tone frequencies.

u Push [Z(MENU/GRP)] to exit the AGC set mode.
