5RECEIVE AND TRANSMIT
■AGC function
The AGC (auto gain control) controls receiver gain to
produce a constant audio output level even when the
received signal strength is varied by fading, etc.
The transceiver has 3 AGC characteristics (time con-
stant; fast, mid, slow) for non-FM mode.
The FM mode AGC time constant is fixed as
‘FAST’(0.1 sec.) and AGC time constant cannot be
selected.

•AGC time constant selection

qSelect non-FM mode.
wPush [AGC] several times to select AGC fast, AGC
medium (MID) or AGC slow.

•Selectable AGC time constant (unit: sec.)

•Setting the AGC time constant

qSelect the desired mode except FM mode.
wPush [AGC] for 1 sec. to enter AGC set mode.
ePush [AGC] several times to select FAST time
constant.
rRotate the tuning dial to set the desired time con-
stant for ‘AGC FAST.’
•AGC time constant can be set between 0.1 to 8.0 sec.
(depends on mode) or turned OFF.
•Push [(F-3)DEF] to select a default value.
tPush [AGC] to select medium time constant.
yRotate the tuning dial to set the desired time con-
stant for ‘AGC MID.’
•AGC time constant can be set between 0.1 to 8.0 sec.
(depends on mode) or turned OFF.
•Push [(F-3)DEF] to select a default value.
uPush [AGC] to select slow time constant.
iRotate the tuning dial to set the desired time con-
stant for ‘AGC SLOW.’
•AGC time constant can be set between 0.1 to 8.0 sec.
(depends on mode) or turned OFF.
•Push [(F-3)DEF] to select a default value.
oSelect another mode except FM. Repeat steps e
to iif desired.
!0 Push [EXIT/SET] to exit the AGC set mode screen.
