24. MODIFICATIONS
+These modifications require you to do some soldering. Attempt only if you are experienced in using an iron on PCBs. Otherwise, refer to qualified personnel. After modification the warranty becomes discretionary.
+Excuse us for repeating ourselves once again: BEHRINGER is not responsible for anything what happens after you start disassembling your EURODESK MX9000. Don't even think of it, if you make much of your warranty privileges.
+Links should not be threaded into holes on the PCB. They should be soldered to the tinned areas around the holes, and bowed slightly upwards in between.
