C A U T I O N Before connecting the lightwave receiver to the power source, you must set the
rear-panel voltage selector correctly to adapt the lightwave receiver to the
power source. An improper selector setting can damage the Agilent 83430A
when it is turned on.
1 Locate the line-input connector on the instrument’s rear panel.
2 Disconnect the line-power cable if it is connected.
3 Use a small flat-blade screwdriver to pry open the fuse holder door.
C A U T I O N You must remove the voltage tumbler to change the voltage selector. Rotating
the voltage tumbler while it is in the line module damages the line module.
4 Remove the voltage tumbler, and replace the tumbler so that the desired line
voltage value shows through the small opening in the fuse holder door.
5 The fuse is housed in a small container next to the voltage tumbler. Insert the
tip of a screwdriver on the side of the container and gently pull outward to
remove the container.
A spare fuse is stored below the line fuse.
