11.  Mounting into the case 

After  concluding  the  assembly  of  the  main  PCB  and  the  display 
module, they are mounted to the top case part. 

1.  Insert  the  4  long  counter-sunk  screws  from  the  case  front  (A, 

B,  C,  D),  add  2  washers  each  and  tightened  with  1  short 
threaded stud. 

2.  Cut out the white areas of the front sticker and attach it to the 

case. The sticker matches exactly the framed part of the case. 
Work very precisely here. 

3.  Add one washer each, mount the main PCB and fix it with the 

remaining 4 short threaded studs.   

 

4.  Mount  the  bottom  case  part  and  fix  it  using  the  case  screws. 

Pay once again attention not to quench the SX-bus cable. 

5.  The rotary knob is assembled. Leave a space of about 1mm to 

the front to ensure the push button option of the rotary switch  

6.  Attach the cover to the rotary knob.
