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.
WARNING
Looking into the optical connector while the light source is active 
WILL result in permanent eye damage. EXFO strongly recommends 
to TURN OFF the unit before proceeding with the cleaning 
procedure.
IMPORTANT
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.
IMPORTANT
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.
