While operating on CW on the Main band (VFO-A), the ACM feature provides a visual indicator of encroachment by
another station (someone you may not be able to hear because of the tight DSP filter in your FT
of a nearby strong signal will be displayed on the Sub-receiver's S-meter. The Sub (VFO-B) receiver is taken over by the
ACM, when engaged, and reception on the Sub band (VFO-B) is not possible while ACM it turned on.
To activate the Adjacent Channel Monitor, press the [ ACM ]
switch. The LED imbedded in the switch will glow Red.

If you do not have Dual Receive engaged, turn-
ing on the ACM feature will cause the [ RX ] LED
associated with the Sub (VFO-B) receiver to
become illuminated.
When ACM is turned on, the frequency of the
Sub (VFO-B) receiver will automatically be set
to match that of the Main (VFO-A) receiver.
When operating on Dual Receive, engaging the
ACM feature automatically sets the Sub (VFO-
B) receiver to the same frequency as the Main
(VFO-A) receiver, and by inverting the DSP fil-
ter the Sub receiver is used for monitoring (vi-
sually) for activity outside your current receiver
passband on the Main receiver.

When ACM is turned on during Dual Receive op-
eration, the audio from the Sub (VFO-B) receiver
will disappear.
A typical operating circumstance where ACM can
help is when you are running stations during a con-
test in a 250 Hz bandwidth. If stations suddenly
stop calling you, it may be because another strong
station has started calling CQ near your frequency.
By engaging ACM, your Sub-receiver S-meter will
display the strongest station on the area ±1.2 kHz
from your current operating frequency; if the en-
croaching station is sufficiently close, you might
want to ask him or her kindly to QSY.
