Before turning on main power, please verify the following items once more.
  Have you made all ground connections securely? See page ?? for details.
  Do you have your antenna(s) connected to the rear-panel Antenna jack(s)? See page ?? for details.
  Is your microphone (and/or key or paddle) connected? See page ?? for details.
  If using a linear amplier, have all interconnections been successfully completed? See page ?? for details.
  Please rotate the [AF GAIN] control to the fully counter-clockwise position, to avoid a loud blast of audio when the 
transceiver turns on. See page ?? for details.

Here is the typical start-up procedure for normal operation: 
1.  Turn on the external DC power supply.
2.  Press and hold in the  front-panel  [POWER]  switch 
until the transceiver turns on. After 
about five seconds (ten seconds if the 
optional µ-Tuning Kit is connected), the 
transceiver is ready for full operation.
3.  The transceiver will start up on 7.000.00 MHz LSB, 
and normal operation may begin.
Note:
  To turn power off, press and hold in the front panel 
[POWER] switch for two seconds.
4.  Rotate the [AF GAIN]  knob  to  set 
a comfortable audio level on in-
coming signals or noise. Clockwise 
rotation of the [AF GAIN]  knob 
increases the volume level.
Note:
When using headphones,  start  by rotating  the [AF 
GAIN]  knob  counter-clockwise, then  bring  the  vol-
ume level up after you put the headphones on. This 
will minimize the chance of damage to your hearing 
caused by an unexpectedly high audio level.
5.  Press  the  [(VFO-A)RX]  Indicator/Switch to  engage 
the VFO-A; the imbedded 
LED will glow green.
Advice:
  If you  press  the  [(VFO-
A)RX] Indicator/Switch 
when  the  imbedded  LED 
is already  glowing  green, 
the  LED  will  now  blink 
“on” and “off”;  this  indicates  that the VFO-A re-
ceiver is temporarily muted. Just press the [(VFO-A)
RX]  Indicator/Switch  once  more  to  restore VFO-A 
receiver operation.
6.  Press  the  [BAND]  button corre-
sponding to the Amateur band on 
which  you  wish  to  begin  opera-
tion.
Advice:
  One-touch selection of each Amateur band be-
tween 1.8 and 50 MHz is provided.
  The FT DX 3000 utilizes a triple band-stack VFO 
selection technique,  which permits  you to  store 
up to  three favorite  frequencies and modes  onto 
each band’s VFO register. For example, you may 
store one frequency each on 14 MHz CW, RTTY, 
and USB, then recall these frequencies by succes-
sive,  momentary  presses  of  the [14]  MHz  band 
button. Each Amateur band button may similarly 
have up to three frequency/mode settings applied.
   When the [MHz] button (located to the left of the 
[CLAR/VFO-B] knob), is pressed, the imbedded 
LED  will  glow  orange,  and  then  rotation  of  the 
[CLAR/VFO-B] knob will change the frequency 
in 1 MHz steps.
7.  Press the [ANT] button to select the ap-
propriate antenna for the band in use.
Advice:
When  you make an antenna selection, 
that antenna is “remembered” by the 
microprocessor in conjunction with  the 
VFO register in use.

8.  Press the [MODE] button to select the desired oper-
ating mode.
  Repeated presses this button, step 
through the available selections.
  Press and hold in the this button, will 
toggle to the alternate mode.
  For example, In the LSB or USB modes, press and 
hold  in  the  this  button toggles  between  “LSB” and 
“USB” mode.
Advice:
  By convention in the Amateur bands, LSB is 
used on the 7 MHz and lower bands (with the 
exception of 60 meters), while USB is utilized on 
the 14 MHz and higher bands.
  When changing modes from SSB to  CW, you 
will  observe  a frequency shift  on  the  display. 
This shift represents the BFO offset between the 
“zero beat” frequency and the audible CW pitch 
(tone) you can hear (the pitch is programmed via 
the Menu  item  “055  MODE  CW  CW  PITCH”), 
even though the  actual tone that you  hear is not 
changing.
  When operating on the FM mode, rotate the 
[SQL] (Squelch) knob clockwise to the point 
where the background noise is just silenced. This 
is the point of maximum sensitivity to weak sig-
nals. Excessive advancement of the [SQL] knob 
will degrade  the  ability  of  the  receiver  to  detect 
weak signals.
  You may  change  the  [RF/SQL] knob from the 
RF GAIN function to the squelch function via 
Menu item “036 GENERAL RF/SQL VR”.
9.  Rotate the Main Tuning Dial knob to tune around the 
band, and begin normal operation.
Advice:
  Clockwise rotation of the Main Tuning Dial knob 
increases the operating frequency, one “step” 
of  the synthesizer  at  a  time;  similarly,  counter-
clockwise rotation of the Main Tuning Dial knob 
will decrease the frequency. Two settings, one 
“normal” and one  “fast”,  are available  on each 
operating mode. Pressing the [FAST] button 
engages the “Fast” tuning selection, see chart be-
low.
  It is possible to set the frequency change over one 
dial rotation, separately for the CW mode, using 
the Menu items “084 TUN DIALSTP” and “085 
TUN CW FINE”. See page 116.
  If  you  want to navigate  rapidly,  so  as  to effect 
rapid frequency change,  there  are several  tech-
niques available:
  Direct keyboard entry of the frequency.
  Use  the  [CLAR/VFO-B]  knob  to tune  in  1 
MHz steps.
  Use the microphone’s [UP]/[DWN] scanning 
keys, if your microphone is so equipped.
