Cleaning Optical Assembly

Battery Replacement

The optics of the MFI must be kept free from dirt or other contaminants to ensure 
operating efficiency and accurate Fiber ID detection. 
Follow your company’s approved cleaning procedures. 
AFL recommends using lint free FiberWipes

 and FCC2 cleaning fluid.

 

Remove the MFI’s plunger cover.

 

Lift the plunger from the two retaining pins.

 

Dampen the wipe with the FPF1 or FCC2 cleaning fluid and gently clean the 
exposed prism and optical windows.

 

Once completed, replace the plunger and plunger cover.

MFI

When a battery icon appears at the top of the MFI display, the 2 x 1.5 V AAA 
alkaline batteries require replacement. To replace the discharged batteries:

 

Remove the retaining screw and slide the battery plate away from the unit.

 

Replace the discharged batteries.

 

Replace the battery plate and retaining screw.

MFT and MFP

When the battery indicator lights on the MFT/MFP unit, the 2 x AA alkaline batteries 
require replacement. To replace the discharged batteries:

 

Turn the MFT/MFP unit Off.

 

Remove any cable connected to the MFT/MFP.

 

Remove the protective boot from the MFT/MFP unit.

 

Open the battery retaining door located on the back of the unit.

 

Replace the discharged batteries.

 

Close battery retaining door.

 

Insert the MFT/MFP unit back into its protective boot.
