inch flat-bladed screwdriver and a TORX T-15 screwdriver to

Removal. Use this procedure to remove the front panel cable, front USB cable,
display cable, and main board. Refer to figure 4--9 for these procedures.
1. Place the oscilloscope assembly face down on a soft surface (such as an
anti-static mat), with the bottom facing you.
2. Remove the front-panel cable from connector J700.
3. Remove the front-panel USB Host cable from connector J805.
4. If present, start to remove the clip from the display cable, at connector J500,
to the position shown in the upper illustration in Figure 4--9. There is not
sufficient clearance to completely remove the clip until the main board is
loosened.

that secure the main board to the front-panel assembly. See Figure 4--9.
6. Release the two snaps that hold the main board (see Figure 4--9). Lift the
main board out of the front-panel assembly.
7. Use the

connector J500 on the main board. See Figure 4--9.
