1. Assemble equipment and locate modules to be removed: Locate the power

CAUTION. When powering off the instrument, use the Windows XP shut down
procedure. (Choose Shut Down from the Start menu.)
Powering down the instrument without using the Windows XP shut down
procedure can corrupt the software on the hard disk.
2. The instrument has a built-in soft power-off function that safely powers off
the instrument when you press the On/Standby switch. You must power off
the instrument using the Windows XP shut down process before depressing
the front panel On/Standby switch.
3. Power off the rear panel power switch before servicing the line fuses or
power cord.
4. Orient the instrument: Set the instrument so its bottom is down on the work
surface and its rear is facing you. If you are servicing the line fuses, do the
next step; if you are servicing the line cord, skip to step 6.
5. Remove line fuses: Find the fuse caps on the rear panel. Now, remove both
fuse caps by turning them counterclockwise using a flat-bladed screwdriver,
and remove the line fuses. Reverse procedure to reinstall.
6. Remove line cord: Find the line cord on the rear cover. Pull the line cord
away to remove from the AC power connector. Reverse procedure to
reinstall.
