ELECTRICAL SHOCK HAZARD. Severe electrical shock, which
could cause physical injury or death, can result from working on an instrument when
the high voltage power supply is operating. To avoid electrical shock, disconnect the
power supply to the instrument, unplug the power cord, and wait at least 1 minute
before working on the instrument.
The fuses are located in the Power Entry Module.

module, and open the door.
3 Pull the fuse compartment out.
There are two fuses in the fuse compartment.
