Remove the dust cap from the connector ferrule, thus exposing the connector endface.

If a CLETOP cassette cleaner is not available, proceed to Step 6. Otherwise, hold the CLETOP cassette cleaner in the palm of your hand with the cassette shutter door facing up.

Rotate the cassette lever all the way down with your thumb. Do not release the lever. The lever advances the "dry" Luminex cleaning cloth inside the case and simultaneously opens the shutter. The CLETOP cassette shutter door is now open and ready for cleaning the connector.

Insert and press the connector ferrule endface perpendicular against the cleaning cloth in the first of two slots of the cleaner.

Drag it down (in the direction indicated by the arrows on the cleaner). Make certain not to release the lever of the cassette.

Lift the connector from the first slot and rotate it 90 degrees and repeat the downward motion using the second slot. Be sure the ferrule is pressed snug against the cleaning cloth while dragging the ferrule to assure the proper cleaning action.

Release the cassette lever allowing the shutter door to close to its initial position. Proceed to Step 7.

Wrap a Luminex cleaning cloth around the ferrule and rotate the connector housing, cleaning the outside periphery of the ferrule.

Follow this by folding an unused portion of the cloth over the end of the ferrule endface and then with light pressure from the thumb, slightly drag the cloth from the center of the ferrule to the edge while rotating the connector 360 degrees. If the Luminex cleaning cloth is not available, a cleanroom optic wipe can be used. The Luminex cleaning cloth is washable and can be used multiple times; optic wipes are single use and disposable.

Inspect the connector for cleanliness. If necessary, repeat the cleaning process.
