Seal Application (Post-MOD DOT 13)
Secure the loose cable to the side, ensuring that it is away from the bot-
tom of the CSMU. This will keep the cable out of access while applying the
new CSMU seal.
If necessary remove the damaged seal by peeling the seal up from the
edge. Take care to not damage the circuitry affixed to the bottom of the
CSMU.
Ensure that the flat underside surface of the CSMU is clean.
Seal Application (Post-MOD DOT 13)
Carefully peel the paper backing from the CSMU Cover Seal (1-200) and
position seal into place on the CSMU memory assembly (1-185). Place the
cut out in the seal around the CSMU circuitry with the notch oriented to-
wards the memory cable. The sticky side of the seal should be against the
CSMU cover. (See Figure 709.)
Smooth the seal down onto the CSMU memory assembly, such that the
application is toward the memory interface cable assembly. Carefully work
