Mute Feature -- Vfo-A; Audio Limiter (Afl) Feature - Yaesu FT DX 9000 CONTEST Operation Manual

If the optional Dual Receive Unit (RXU-9000) is installed, during Dual Receive operation it is possible to mute the VFO-
A audio temporarily, without touching the setting of the [ AF GAIN ] control for the VFO-A.
This capability is particularly useful if you wish to concentrate on the signal being received on the VFO-B during Dual
Receive operation.
Press the VFO-A band's [ RX ] LED/switch.
The VFO-A audio will be silenced, and the green LED in
the [ RX ] switch will blink. To restore reception on the VFO-
A, just press the blinking [ RX ] switch/LED once more.
If the optional Dual Receive Unit (RXU-9000) is installed, the Audio Limiter (AFL feature is available on both the VFO-
A and VFO-B.
As a reminder, there is no difference in the fundamental performance of the two VFOs. Please see page 71 for details.
