W A R N I N G SHOCK HAZARD!
The backlight inverter assembly, which is mounted at the front corner of the oscilloscope near
the flat-panel display, operates at 1.3 kV at turn on. DO NOT handle this assembly while it is in
operation. An LED on the inverter board illuminates to indicate the presence of high voltage.
W A R N I N G INJURY CAN RESULT!
Once the cover is removed, the fan blades are exposed both inside and outside the chassis.
Disconnect the power cable before working around the fan. Use extreme caution in working with
the oscilloscope when the cover is removed. Install the fan safety shield (Agilent Technologies
P/N 54810-00601) on the side of the chassis over the fan. Failure to observe these precautions
may result in injury.
For information on how to replace the display parts, see "Replacing Assemblies," beginning on
page 101.
