before working around the fan. Use extreme caution in working with the oscilloscope. Failure
to observe these precautions may result in 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.

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.
To install the fan, reverse this procedure.
