OPERATION

Adjusting  the  Color  Processor  Controls

Even  though  the  controls  on  the  Color  Processor  are  more  sensitive  and 
selective  than  the  controls  on  your TV,  they  do  interact  with  each  other  and  with 

the  controls  on  your TV,  VCR,  and  other  video  equipment.  Follow  the 

instructions  below  and  the  instructions  in  the  ow ner’s  manuals  for  your  other 

video  components.

Refer  to  "Controls  and  Functions”  on  page  4  for  details  on  the  effect  of  each 
control  and  switch.

1.  Set  all  the  Color  Processor  control  knobs  and  switches  as  described  in 

"Preparation  for  Use."

2.  Turn  on  your  TV  and  set  it  to  the  same  channel  as  the  channel  switch  on 

the  RF  modulator  you  are  using  (or  set  your  TV  to  "m onitor” ).

3.  Set  the  SOURCE  A 'B   switch  for  the  desired  input  source  and  begin 

playback  from  the  selected  input  source  (VCR  or video  disc  player).

4.  If  you  are  using  an  enhancer/stabilizer/m odulator  or  similar  product,  adjust  it 

as  described  in  its  ow ner's  manual.

5.  Adjust  the  INTENSITY  control  for  the  desired  picture  brightness.

6.  If there  is  no  color  in  the  picture  (and  you  are  playing  a  color  tape)  center 

the  BURST  control  and  adjust  the  CHROM A  control  for  the  desired  amount 
of  color.

7

.

  Adjust  the  BURST  control  for further fine  tuning  ol  the  color  intensity.

8.  Adjust  the  HUE  control  to  achieve  the  desired  color  tint  (especially  flesh 

tones).

Continue  fine  tuning  each  Color  Processor control,  along  with  the  controls  on 
your  other  video  equipm ent,  to  obtain  the  desired  results.

Use  the  BYPASS  setting  of  the  MODE  switch,  at  any  time,  to  com pare  the 
processed  and  unprocessed  pictures.
