as shown in Figure 17.
Figure 17
7 There are two tabs on the edge closest to the touch screen that need to be disengaged. To disengage the
one near the top of the oscilloscope, look down the edge from the top and press in on the tab (meaning
press straight towards the bottom of the oscilloscope) with a flathead screwdriver while pulling up on
the plastic keyboard cover / keyboard. The plastic piece and keyboard will not come all the way off
because you need to repeat this procedure for the bottom tab (look along the inner edge from the bottom,
push in on the bottom tab (meaning push towards the top of the oscilloscope), and then pull up on the
plastic keyboard cover / front panel keyboard). Figure 18 shows a picture of performing this procedure
on the upper tab.
