Preparing the Analyzer for Use

To change the IF section’s fuse

The fuse is installed at the factory to match the most commonly used line voltage in the country of destination.

1Unplug the power cord from the IF section (the section with ‘’Agilent 89410A’’ silk screened on its lower right rear panel).

2Using a small screw driver, press in and turn the fuse holder cap counter-clockwise. Remove when the fuse cap is free from the housing.

3Pull the fuse from the fuse holder cap.

4To reinstall, select the proper fuse and place in the fuse holder cap.
