dirty, oxidized, rusted or otherwise compromised.  If repair is required, do it before installing the

  Back up your patches if they are important to you!

 

 

Open the DX7 

 
Using a Philips head screwdriver, 

remove the 5 screws from the front panel

. Two are located 

on the left front. Two are located on the right front. A final one is located on the right rear. Set the 
screws aside, noting that the rear panel one is the shortest. 

              

 

 

(Re)Move the Keybed & Remove the Keyboard Rail 

 
It can be difficult to see the delicate pins when installing the DX-MAX(3)+  board. By moving the 
keybed  (the  chassis  with  the  keys)  and  removing  the  silver  keyboard  rail,  you  will  have  better 
sight lines and freedom of movement when installing the DX-MAX(3)+  board.  
.  

Remove  the  4  large  external  screws  from  the  underside  of  the  keyboard

  along  the  front 

edge. The photo below shows the inside front edge of the empty case bottom and illustrates the 
location of the 4 screws. You will, of course, be unscrewing from the DX7 underside. 

 

 

 

Loosen  the  3  internal  screws  at  the  extreme  right  and  left  ends  that  hold  the  keybed  in 
place

. It is not necessary to extract them from the holes they reside in.
