4.0  OPERA 

TI 

ON 

This  section  is  intended  to  familiarize  you  with 
the  various  operating  features  of  the  transcei­
ver.  The  early  subsections  describe  in  detail 
the  basic  operating  procedures  for  the  receiver 
and  transmitter.  However,  for  these  to  work  as 

described  it  is  assumed  that  you  have  performed 

each  step  in  the  order  given,  from  the  start: 

that  you  have  already  read 

§'2, 

and  are  familiar 

with  the  locations  and  basic  functions  of  the 
various  controls  and  switches;  and  that  the 
transceiver  has  been  installed  as  described  in 

§3. 

If  not,  please  read 

§'2 

and 

§3 

now. 

Subsections  4.8  through  4. 12  describe  the  more 

complex 

operations 

involving 

programmable 

features,  memories  and  scanning.  We  do  not 

recommend  random  experimentation  with  the 
controls  until  after  you  have  followed  these 
procedures.  Some  keys  and  switches  alter  or 
disable  other  functions  and  may  cause  confusion. 

Although  this  should  not  damage  the  equipment, 
you  may  have  to  turn  o ff  the  transceiver  and 
press  the  BACKUP  switch  (twice)  to  reset  the 
memory  system  ( 

§3.6 ) 

if  you  loose  track  of  opera­

tion.  If  the  location  or  basic  function  of  a 

control or  switch  is  unclear,  refer  to 

§'2. 

Subsections  4. 13  through  4. 18  offer  some  sugges-
tions  for  implementing  features 
applications.  The  comments  and 
these  final  sections  are  intended 

in  different 

procedures  in 

to  guide  your 

own  experimentation,  rather  than  to  serve  as  a 
last  word  on  the  best  way  to  operate:  ultimately 
it  is  up  to  you  to  choose  the  best  features  and 
techniques  for  your  own  operating preferences. 

4.1 

Preliminary  Steps 

Before  plugging  in  the  power  cord  to  the  wall 
outlet,  double  check  that  the  AC  voltage  label 
on  the  rear  panel  match  your  line  voltage.  Also, 
set  the  BACKUP  switch  on  (undepressed  position) 

if  it  is  not  already.  Set  the  front  panel  power 

switch  to  the  OFF  (undepressed)  position. 

Connect  a  microphone,  if  desired,  to  the  MIC 

jack.  For  CW  operation,  connect  your  CW  key  or 
keyer  paddles  to the  KEY  jack. 

Preset the  front panel  controls: 

MIC,  D RIVE 

NB-----------fully  counterclockwise 

SQL-----------------------------fully  counterclockwise 

(but  not into  the  click-stop) 

AF------------------------------------ counterclockwise 

RF ----------------------------------------fully  clockwise 

All  other  controls-----------------------------midrange 
All  pushbutton  switches----------- out  (undepressed) 

4.2 

Initial  Power  Up,  Band  Selection 

Plug  the  AC  power  cord  into  the  wall  outlet,  and 

press  the  POWE R  switch.  The  meter  and  display 

should  light  up,  with  the  display  indicating  the 
default  settings  if  the  transceiver  has  not  been 

used  before:  LSB  (lower  sideband  mode),  VFO-A, 

.000.00  (MHz).  Set  the  DIM  selector  (below  the 

left  edge  of  the  display)  for  comfortable  dis­
play  brightness.

Press  the  BAND/MCH  keys  (to  the  right  of  the 

tuning  knob)  and  observe  the  band  changes  on  the 
display.  In  the  default  (Ham)  mode,  the  HF  ama­

teur  bands  are  selected.

Press  the  H/G  (ENT)  key  (at  the  lower  left  of  the 
keypad)  once.  The  green  GEN  indicator  just 

beneath  the  frequency  display  should  glow.  Now 

press  the  BAND/MCH  keys  and  again  observe  the 

band  changes  on  the  display.  In  this  (General 
Coverage)  mode,  the  receiving  frequency  changes 
by  500  kHz  for  each  BAND  step.
