³ Always inspect fiber-optic connectors before using them and clean them if

necessary.

³ Keep the unit free of dust.

³ Clean the unit casing and front panel with a cloth slightly dampened with water.

³ Store unit at room temperature in a clean and dry area. Keep the unit out of

direct sunlight.

³ If any liquids are spilled on or into the unit, turn off the power immediately,

disconnect from any external power source, remove the batteries and let the

unit dry completely.

WARNING

Use of controls, adjustments, and procedures for operation and

maintenance other than those specified herein may result in

hazardous radiation exposure.

Cleaning EUI Connectors

Regular cleaning of EUI connectors will help maintain optimum performance. There

is no need to disassemble the unit.

IMPORTANT

If any damage occurs to internal connectors, the module casing will

have to be opened and a new calibration will be required.

To clean EUI connectors:

1. Remove the EUI from the instrument to expose the connector baseplate and

ferrule.

Turn

Push

2. Moisten a 2.5 mm cleaning tip with one drop of isopropyl alcohol (alcohol may

leave traces if used abundantly).

3. Slowly insert the cleaning tip into the EUI adapter until it comes out on the other

side (a slow clockwise rotating movement may help).

5. Repeat steps 3 to 4 with a dry cleaning tip.

Note: Make sure you don’t touch the soft end of the cleaning tip.

6. Clean the ferrule in the connector port as follows:

6a. Deposit one drop of isopropyl alcohol on a lint-free wiping cloth.

IMPORTANT

Since isopropyl alcohol is not absolutely pure, it may leave residues

if used abundantly or left to evaporate (about 10 seconds).

Avoid contact between the tip of the bottle and the wiping cloth,

dry the surface quickly, and use a bottle that distributes only a drop

of alcohol at a time.

6b. Gently wipe the connector and ferrule.

6c. With a dry lint-free wiping cloth, gently wipe the same surfaces to ensure

that the connector and ferrule are perfectly dry.

6d. Verify connector surface with a portable fiber-optic microscope (for

example, EXFO’s FOMS) or fiber inspection probe (for example, EXFO’s

FIP).

WARNING

Verifying the surface of the connector WHILE THE UNIT IS ACTIVE

WILL result in permanent eye damage.

7. Put the EUI back onto the instrument (push and turn clockwise).

8. Throw out cleaning tips and wiping cloths after one use.
