Removing the Cabinet
WARNING
Before removing the cabinet, disconnect the power cord from the back of the
instrument. As the cabinet is being removed, do not touch any component on the
CRT circuit board which is mounted in the chassis under the CRT.
The cabinet can be removed by loosening the screws retaining the rear panel and taking out the one screw that secures
the cabinet to the bottom of the chassis. Carefully slide the cabinet off the chassis, being careful not to touch any
conponents on the CRT circuit board. To reinstall the cabinet, slide it over the chassis. Ensure that any cable leading
from the boards fits into the recess in the boards. See Figure 6-4.
Figure 6-4. Cabinet removal.
Removing the Front Panel
Front panel removal is accomplished by using a 1/16-inch hex key wrench to remove the four screws holding the front
panel in place. Unsolder the lead to the screw post, then carefully pull the front panel away from the 318/338 and lay it
face-down in front of the instrument. To reinstall the front panel, resolder the lead to the screw post, position the panel in
place, and secure it with the four screws.
