1.4 - REPLACEMENT OF THE FUSE
Before starting to replace the fuse, try to find out the possible causes which could have
caused the break (short circuits in the power wires of the equipment, humidity, breakdown
of electronic components inside the equipment, etc.). Proceed with the replacement of the
fuse, using one having the same characteristics, after having identified the cause of the
break.
To replace the fuse, follow the operations described below.
1. Take a 3.15 Ampere, 5x20mm fast fuse.
If the equipment is supplied with the Power Outputs Connector, use a 10 Ampere,
5x20 mm fast fuse.
