Chapter 5: Replacing Assemblies

To remove and replace the front panel assembly

1 Disconnect the power cable and remove the cover, top plate, and bottom plate

as described earlier.

2 If you are removing the keyboard, grasp and pull on all knobs located on the

front panel to remove them (Figure 5- 9). If you are not removing the keyboard,

this step is not necessary.

Figure 5-9

Disconnect the display cable and on/off cable from the motherboard end of the

cables.

4 Disconnect the USB and front panel power cables from the front panel (these

are accessible from the top side of the oscilloscope).

5 Turn the oscilloscope upside down and disconnect the two semi- rigid Cal Out/

Aux Out cables from both the front panel and backplane board. As Figure 5-

10 shows, first disconnect the cables from the rear side of the Cal Out connections

and then pull straight back to remove the cables from the backplane board.

CAUTION: Be sure to pull straight back to avoid bending or breaking the

connection to the backplane board.

When reconnecting these cables, torque the Cal Out connection to 8 in- lbs.
