7-4. Make sure none of the LED wires have been bent.
7-5. Set the display lens in position, making sure that the
"AM-SSB" lettering is facing correctly. The lens is locked into
place by carefully melting with your soldering tip the 6 molded
posts inside the panel along the sides and bottom of the lens.
(If you are reluctant to do it this Way, you have the option of
securing the lens to the panel with very small drops of contact
cement at the edges.) Wipe the inside of the lens clean of any
fingerprints.
7-6a. Glue the front panel headphone jack insert in place.
This is a custom-molded washer-like plastic part. (The large hole
in the front panel is designed to accept connectors of various
types using the proper insert.) Use just a drop or two of any
fast-drying glue such as contact cement dried properly on both
surfaces. Do not use "superglue" here -- there is too much risk
of damaging the front panel surface.
