This section contains instructions for user and preventive
maintenance. If the instrument does not function properly, it
should be referred to qualified service personnel or returned
to Tektronix for service. Packaging directions for shipment
are on page 1-9.
Cleaning or Replacing the Fan Filter
To ensure adequate air flow, it is essential to clean or replace
the rear-panel fan filter regularly. The interval between filter
cleaning or replacement is determined by the operating envi-
ronment.
To remove the filter, take out the two screws that fasten the
housing to the rear panel.
Remove the filter and wash it in a mild detergent and water
solution. Place cleaned and dried filter (or new filter) in the
housing and replace housing over the fan. Replace and tight-
en the two screws (8 in lbs).
The filter part number is shown on page 1-7.
Fuse Replacement
Remove the fuse cap from the rear panel and replace the fuse
cartridge with a 250V, 2A, F-type fuse as specified on the
rear panel.
