CompactFlash Card
The settings for the instrument operating parameters are written to a CompactFlash mem-
ory card. The parameters can be transferred quickly from one device to another (e.g. a re-
placement device) by simply swapping the memory card.
2.4
Fan
The instrument has a fan which draws in cool air via the ventilation openings in the front
panel and blows the warm air out via the rear panel.
The fan is mounted on the outside of the rear panel and can therefore be changed without
opening the cover on the instrument.
If a fan fails a warning message is generated. If the temperature then increases too much,
a fault message is output and the instrument is shut down in order to prevent the electronics
from overheating.

ATTENTION!
The CompactFlash card can only be inserted into another R&S SLx8000 and must never 
be inserted into a card reader. The latter will render the card unusable for the R&S 
SLx8000.
