Cleaning Fixed Connectors
Regular cleaning of connectors will help maintain optimum performance. Do not try
to disassemble the unit. Doing so would break the connector.
To clean fixed connectors:
1. Fold a lint-free wiping cloth in four to form a square.
2. Moisten the center of the lint-free wiping cloth with only one drop of isopropyl
alcohol.
3. Gently wipe the connector threads three times with the folded and moistened
section of the wiping cloth.
4. With a dry lint-free wiping cloth, gently wipe the same surfaces three times with
a rotating movement.
5. Throw out the wiping cloths after one use.
6. Moisten a cleaning tip (2.5 mm tip) with only one drop of isopropyl alcohol.
7. Slowly insert the cleaning tip into the connector until it reaches the ferrule
inside (a slow clockwise rotating movement may help).
8. Gently turn the cleaning tip one full turn.

Alcohol may leave traces if used abundantly. Avoid contact between
the tip of the bottle and the wiping cloth, and do not use bottles
that distribute too much alcohol at a time.

Isopropyl alcohol takes approximately ten seconds to evaporate.
Since isopropyl alcohol is not absolutely pure, evaporation will leave
microscopic residue. Make sure you dry the surfaces before
evaporation occurs.
