SPEED HOLE                
                                
                                          
 TURN YOUR WALKMAN LIKE A  TURTLE.  THERE 
 MIGHT  BE  SOMETHING  THERE  THAT  LOOKS 
 LIKE  A SCREW HOLE BUT  IT  COULD  BE  A 
               SPEED HOLE.                
 THE   RULE  IS   IF  YOU  CAN'T  GET   A 
  REASONABLY SMALL SCREWDRIVER IN THERE,  
          IT'S NOT A SCREW HOLE.          
                                          
                 USAGE                  
                                          
 USE  THE  SPEED  HOLE LIKE A  SCREW HOLE 
      BUT WITH A TINIER SCREWDRIVER       
                                          
                  THIS                  
                 ADJUSTS                
                   THE                  
                PITCH                 
                                          
 SOME CASSETTE  PLAYERS HAVE SPEED SCREWS 
 BUT  NO HOLES FOR THEM.  TO GET TO THOSE 
 SCREWS  YOU  NEED  TO  DISSASEMBLE   THE 
 WHOLE   THING.   COULD   BE   WORTH   IT
