Removing the Front Panel Assembly
Figure 3-5. Removing the Front Panel Assembly
Remove the five 4-40 x ¼-inch flathead machine screws that attach the
front-panel assembly to the bottom of the chassis.
Remove the two 6-32 x ¼-inch flathead machine screws from the
countersunk holes at each side of the front the end of the chassis.
While holding the front panel assembly with one hand, use the fingers of your
other hand to continue to loosen the nut on the Channel 2 input connector.
Gently pull the front panel assembly away from the chassis as you loosen the
nut until the front panel assembly is completely disconnected.
When reattaching the front panel assembly, reverse the procedure above.
You must use a microwave torque wrench to tighten the nut that attaches
the Channel 2 input connector to the sampler. Using any other tool to
tighten the coupling nut will damage the connector, the sampler, or both.
