Figure 5-15
Disengage the tabs located along the edges of the control panel faceplate. There are
6
three tabs located along the right hand side (see Figure 5-16). There are two additional
tabs located on the top and bottom of the left edge. You will need to look inside the
instrument to see these tabs and hence, you need the top and bottom plates removed
as discussed in step 1. You can see the top left side tab by looking through the top cavity
while you can see the bottom left tab by turning the oscilloscope on its side and looking
through the bottom cavity. See Figure 5-17 and Figure 5-18 for pictures of these left
side tabs.
Pull off both the control panel faceplate and front panel circuit assembly together after
7
all the tabs are disengaged. The faceplate and the circuit assembly will not come all
the way off the instrument until you disconnect all the cables connected to the front
panel circuit assembly. Once the combination of the faceplate and the assembly has
been removed, remove the faceplate from the assembly.
