HOW TO FIX THE SQUEAL IN A CASIO HORN.
This is the most common fault and the reason most people start searching the internet for information, so here goes:
HOW TO FIX THE SQUEAL (DH-100 and DH-200.)
Follow these instructions:-
Remove the mouthpiece, batteries and all the case screws (don't forget the one in the battery compartment).
Once opened you will see two printed circuit boards, one on top of the other. Remove the screws from the top board and carefully turn the board over. At one edge of the board you will see the offending capacitor. (C39 which is 33uF)
Very carefully and without damaging the circuit board, either unsolder or cut the capacitor out. I usually wriggle the capacitor with a small pair of pliers until it breaks free. Then unsolder or cut off any remaining legs. Double check with a magnifying glass if possible to be really sure that you have not left a short circuit here! The capacitor can also leak a corrosive fluid, so make sure the circuit board is dry before continuing. A cloth soaked with alcohol will clean it.
Insert a 33uF electrolytic capacitor in the feed through holes on the board. (see photos). There's a circled '+' sign to show which hole the positive side goes into.
Any type of capacitor will do as long as its small enough to fit in the the space available. The voltage rating should be at least 6V.

Make sure you use the right holes!
Double check the polarity before soldering in place. Trim the excess wire off the legs of the capacitor and that's it!!
Re-assemble your horn and enjoy.
