holding

  the

Func

  button,  and  while 

still  holding  the 

Func

  button,  press  the 

L  Dn

  (Thresh)  button.  The  display  will  show  the

While  holding  the 

Func

  button,  the  bargraph  display  will  show  the  following  pattern,  to 

indicate  that  the AT-200ProII  is waiting  for you  to push  a button  to check  its  status:
