To remove and replace the handle

To remove and replace the handle

•Remove the two screws in the endcaps, then lift off the handle.

To remove and replace the feet and tilt stand

1Remove the screws connecting the four rear feet to the instrument.

2 Separate the rear feet from the instrument to remove them. 3 Press the locking tab on the bottom feet, then remove them.

4Remove the tilt stand from the bottom front feet by lifting the stand up and out of the foot.

5Reverse this procedure to install the feet and tilt stand.

To remove and replace the cover

1Disconnect the logic analyzer cables from the rear panel.

2Using the previous procedures, remove the handle and the four rear feet.

3Remove the seven screws from the front molding, then slide the molding forward to remove it.

4Remove the cover.

To remove the cover, set the instrument upright and facing toward you. Slide the chassis toward the front, out of the cover, and set it on a static-safe work area.

5Reverse this procedure to install the cover.

Check that all assemblies are properly installed before installing the cover.

When installing the chassis in the cover, check that the tabs located at the bottom, rear of the cover align with the holes in the rear panel.
