WARNING AVOID INJURY!
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 to avoid injury.
Use this procedure to remove and replace the fans. When necessary, refer to
other removal procedures. The graphics in this chapter are representative of
the oscilloscope at the time of this printing. Your unit may look different.

CAUTION AVOID OVERHEATING THE OSCILLOSCOPE
When replacing the fan, be sure the direction of the fan air flow is coming from the
inside to the outside of the oscilloscope. Check the flow arrows on the fan and check
for proper flow once power is applied to the oscilloscope. Improper air flow can overheat
the oscilloscope.
