When you clean fiber components, always complete the following steps carefully:

Caution: Laser radiation. Risk of eye injury in operation. Do not stare into the beam;

do not view it directly or with optical instruments.

1. Turn off the ION-U system (laser sources) before you inspect fiber connectors.

2. Check the connectors or adapters with a fiberscope before cleaning.

3. If the connector is dirty, clean it with a lint-free wipe (dry cleaning).

4. Inspect the connector.

5. If the connector is still dirty, repeat the dry cleaning technique.

6. Inspect the connector.

7. If the connector is still dirty, clean it with 99% isopropyl alcohol (wet cleaning)

followed immediately with a dry clean in order to ensure no residue is left on

the surface.

8. Repeat steps 5 through 7 until surface is clean.
