requirements for the line voltages. The correct fuse must be installed
in the cardiograph before you turn it on. Fuse rating requirements
are also printed on the product rating label on the back of the
cardiograph.
1. Unplug the power cord from the line module.
2. Open the line module door with a small bit screwdriver.
3. Pull out the fuse holders and check that the line fuses are the
correct rating for the selected voltage. Refer to Table 2-2. If you
need to install line fuses with a different rating, you will also need
different fuse holders. Fuses for lower voltages require fuse holder
part number 2110-0686; fuses for higher voltages require fuse
holder part number 2110-0687.
4. Place the fuses in the fuse holders and push each fuse holder
back into the line module. Make sure that the arrows on the fuse
holders point in the same direction as the arrows on the line
module door.
5. Close the line module door.
