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
