These fuses F10, F11 & 12 are soldered into the power supply and are essential to ensure the
system complies with the European Union’s low voltage directive. Any attempt to replace these
fuses will invalidate the waranty and should not be attempted by the customer. These fuses will
only blow in the event of:

−

Customer abuse, i.e. removing the display with the power still on or incorrect use of outputs.

−

Hardware
