Step 4
Insert the cleaning tool into the first adapter slot. Align the key on the cleaning tool with the matching
notch in the adapter slot. The cleaning tool works only when the cleaning head is properly inserted.
Step 5 Advance the thumb wheel until you hear two hard clicks. This advancement ensures that enough lint-free
cleaning cloth advances across the face of the fibers in the ferrule.
Note The thumb wheel makes a series of soft clicks followed by a “hard click” when turned. The hard click
is represented by six large notches along the edge of the thumb wheel. Always advance the thumb wheel
until you hear two hard clicks.
Step 6 Clean the three visible ferrules and then rotate the array adapter 180 degrees to clean the remaining three
ferrules.
Step 7 Repeat these steps for all optical array cable connectors that require cleaning.
Note Always keep the protective silver dust end-caps on cable connectors that are not in use.
