Switch
Press this button to lower the illumination intensity of
the analog meter and the frequency display. Press it
once more to restore full brightness.
A
DVICE
:
The following Menu items allow you to configure the
dimming levels of each display independently to cus-
tomize the brightness levels.
008 DISP DIM MTR
: for analog meter
009 DISP DIM VFD : for frequency display
010 DISP DIM OLE
: SUB DISPLAY windows
011 DISP DIM ELCD : for Spectrum Scope display
of the optional SM-5000 Sta-
tion Monitor
[
MOX
]
Switch
Pressing this button engages the PTT (Push to Talk)
circuit, to activate the transmitter. The LED inside the
button will glow red during transmit. It must be turned
off (the red LED will be off) for reception. This button
replicates the action of the Push to Talk (PTT) switch
on the microphone. When engaging the [
MOX ] button
or otherwise starting a transmission, be certain you have
either an antenna or 50-Ohm dummy load connected
to the selected Antenna jack.
[
VOX
]
Switch
This button enables automatic voice-actuated transmit-
ter switching in the SSB, AM, and FM modes. While
activated, the LED inside the button glows red. Proper
adjustment of the front panel [
VOX
] and [
DELAY
]
knobs will make hands-free voice-actuated operation
possible.
[
TUNE
]
Switch
This is the on/off switch for the FT
DX
5000 ’s Auto-
matic Antenna Tuner.
Pressing this button briefly, places the antenna tuner in
line between the transmitter final amplifier and the an-
tenna jack (The “
” icon will appear in the dis-
play). Reception is not affected.
Pressing this button for 1/2 second, while receiving in
an amateur band, activates the transmitter for a few
seconds while the automatic antenna tuner rematches
the antenna system impedance for minimum SWR. The
resulting setting is automatically stored in one of the
antenna tuner’s 100 memories, for instant automatic
recall later when the receiver is tuned near the same
frequency.
Pressing this button briefly, while the Tuner is engaged,
will take the Automatic Antenna tuner out of the trans-
mit line.
N
OTE
:
A signal is being transmitted while the tuner is match-
ing the antenna impedance. Therefore, be certain there
is a dummy load or antenna connected to the selected
antenna jack before initiating the tuning sequence.
[
MONI
] (
Monitor
)
Switch
This button enables the transmit monitor in all modes.
While activated, the “
” icon appears in the dis-
play. Use the [ MONI
] knob to adjust the Monitor level.
A
DVICE
:
The Monitor is highly useful for making adjustments
to the Parametric Equalizer, or other voice character-
istic adjustments, while listening with headphones. The
voice quality heard in the headphones is a “natural”
reproduction of the transmitted audio.
[
PROC
] (
Processor
)
Switch
This button enables the Speech Processor for SSB
transmission. While activated, the “
” icon appears
in the display. Adjustment of the Processor level is ac-
complished using the [
PROC ] knob.
A
DVICE
:
The Speech Processor uses a compression technique
to increase the average power output. However, if
the [
PROC
] knob is advanced too far, the increase
in compression becomes counter-productive, and
intelligibility will suffer. We recommend that you
monitor the sound of your signal using the Monitor
(with headphones).
When the optional DMU-2000 Data Management
Unit is connected, you may use the Audio Scope/
Oscilloscope function to help you adjust the set-
ting of the Speech Processor compression level for
optimum performance with your voice and micro-
phone.
[
RX ANT
]
Switch
Press this button to use an antenna connected to the
RX ANT jack on the rear panel for receive.
The “
RX ” icon appears in the display when the RX
ANT is used.
[
ANT 1-4
]
Switch
Move this knob up or down to conveniently select one
of the four antenna jacks on the rear panel. The se-
lected antenna jack is indicated in the ANT column of
the Block Diagram Display.
A
DVICE
:
Press this knob in briefly to quickly select the ANT 1
jack.
