1. Remove the optical connector plate (including the shutter) by unscrewing the two screws.
Figure 5-1 Optical Connector Plate
2. Pull the plate away (2” max to prevent breakage of the fiber). Pull and release the optical con-
nector from the adaptor.
3. Fold a piece of dry lens cleaning paper in half twice (for a 4-ply thickness).
4. Lay the connector on the lens cleaning paper with the tip touching the paper. Pull the connec-
tor across the paper to wipe the tip.
5. If necessary, use one drop of Isopropyl Alcohol to wet part of the paper. Drag the connector
across the wet area to reduce residue on the connector surface. Then drag the connector tip
across the dry area.
6. Assemble the connector back to the adaptor plate. Assemble the plate back to the transmitter
back panel. The mating optical connector has to be cleaned as explained in steps 3 through 6.
WARNING!
Never use a clean air product to spray air into the optical adaptor or on the connector
surface. The air causes dust to condense on top of the optics wave guide which is very
difficult to remove. Never clean a connector when laser light is passed through it.
