Figure 4-28 Main Deck Screws
Replacement
1. If the rear dress panel is removed, secure it to the rear frame using
two nuts. Ensure that the dress panel is aligned with the frame.
2. Place the spectrum analyzer on its front panel allowing easy access
to the rear-frame area.
3. Place the rear frame on the spectrum analyzer and secure the
knurled nut on the earphone jack. A lock washer should be used on
the inside of the rear frame and a flat washer on the outside.
4. Place the coax cable's BNC connectors into the appropriate
rear-frame holes as described below. Use a 9/16-inch nut driver to
attach the dress nuts holding the BNC connectors to the rear frame.
