Adjacent Channel Monitor (Acm) Cw Mode Only - Yaesu FTDX-9000D Operation Manual

T C
There may be occasions, during Dual Receive operation, when you want to silence the Main (VFO-A) receiver temporarily
so as to concentrate on what's being received on the Sub (VFO-B) receiver. The Mute feature makes this simple to accom-
plish.
Press the Main (VFO-A) band's RX LED/switch (#
The Main (VFO-A) receiver will be silenced, and the green
LED in the RX switch will blink. To restore reception
on the Main (VFO-A) receiver, just press the blinking
RX switch/LED once more.
Particularly when the AGC is off, you may desire to limit the level of audio output that is permitted to flow to the speaker
or earphones. For these circumstances, the AFL (Audio Limiter) feature will provide the desired cap on the audio output.
Main (VFO-A) Band AFL Setup
Press the Main (VFO-A) band's AFL switch (#
turn on the Audio Limiter. The imbedded LED in the but-
ton will glow red. To disable the Audio limiter, press the
AFL switch once more; the imbedded LED will turn
off.
Advice
Because the AFL feature will generally reduce the overall
audio level, we recommend that it be left Off unless spe-
cial operating conditions warrant its use.
Sub (VFO-B) Band AFL Setup
1. Press the Sub (VFO-B) band's RX switch to en-
gage Dual Receive operation.
2. Press the Sub (VFO-B) band's AFL switch (#
to turn on the Audio Limiter. The imbedded LED in
the button will glow red. To disable the Audio limiter,
press the AFL switch once more; the imbedded LED
will turn off.
