The FOT contains no user-serviceable parts. However, the unit contains sensitive
electronic and optical components, and should be handled carefully and stored in its
carrying case when not in use.

4.1 Replacing the 9 V Alkaline Battery

1. Power off the unit and remove it from the holster.
2. Open the battery compartment door located at the back of the unit.
3. Replace the battery (respecting polarity).
4. Close the battery compartment door and replace the holster.

4.2 Cleaning the Detector Port

Use the provided cleaning pads or any lint-free cloth dipped in isopropyl alcohol (98%
pure or more) to gently wipe the detector port. Blow-dry with compressed air. Always
replace the protective cap on the detector port when not in use.

4.3 Cleaning the Source Port (FOT-30A)

To prevent dust and dirt from entering the connector(s), always replace the protective
cap on the source port when not in use. Clean the source port using a lint-free swab
dipped in isopropyl alcohol (98% pure or more) and blow-dry with compressed air.
If the unit is equipped with a universal interface (option), rotate the connector
adapter counter-clockwise and remove it. You now have access to the ferrule inside
the connector interface. Clean and blow-dry as explained above. Then replace the
connector adapter and rotate it clockwise until it clicks into place.

4.4 Factory Recalibration

EXFO recommends that the FOT be sent back to the factory every year for adjustment
and/or recalibration to ensure traceability to NIST and to maintain the unit within
published specifications.
