Mute Feature Main (Vfo-A) Band; Audio Limiter (Afl) Feature - Yaesu FTDX9000D - DATA MANAGEMENT Operation Manual

There may be occasions, during Dual Receive operation, when you want to silence the Main (VFO-A) receiver tempo-
rarily so as to concentrate on what's being received on the Sub (VFO-B) receiver. The Mute feature makes this simple to
accomplish.
Press the Main band's (VFO-A) [ 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 band's (VFO-A) [ 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.

Because the AFL feature will generally reduce the
overall audio level, we recommend that it be left
Off unless special operating conditions warrant its
use.
