3. Disassembly Procedures of the fuse
To replace the blown fuse,
1) Unplug the electrocardiograph from AC power. Pull out the AC power cord from the AC
power connector on the rear of the electrocardiograph.
2) Carefully place the electrocardiograph upside down on a flat surface covered with cloth or
other protecting pad.
3) Place a flat-head screwdriver in the gap of the fuse. Apply a certain amount of pressure on the
screw driver to sink the fuse for about 3 mm. Unscrew the fuse anticlockwise.
4) Remove the old fuse. Take out a new fuse supplied by manufacturer or of the same
specification: T3.15AH250V, Ø5×20mm.
5) Place the new fuse in the fuse socket. Press it in and screw it clockwise back in position.
WARNING
Ruptured fuses must only be replaced with those of the same type and rating as the
original.
