3Getting Started with Your Multifunction Loss Tester
CAUTION
To avoid damaging your unit, use it only with modules approved by EXFO.
Turning the Unit On and Off
When you turn the unit on, you may use it immediately under normal conditions (while the source offers good startup performance, you should allow a 5-minute warmup).
When the unit is turned off, it keeps the following parameters in its internal memory:
FASTEST parameters
Current power meter wavelength and list of favorite wavelengths
User-defined thresholds
Autonaming settings
Regional, LCD and energy-saving settings
Saved values and test results
IMPORTANT
If you remove batteries (and the AC adapter/charger is unplugged), the unit will turn off without saving the above elements.
The date and time will be lost only if you remove the clock battery.
Note: To ensure that the power is completely turned off, disconnect the AC adapter/charger and remove the batteries.

Cleaning and Connecting Optical Fibers
Cleaning and Connecting Optical Fibers
IMPORTANT
To ensure maximum power and to avoid erroneous readings:
Always inspect fiber ends and make sure that they are clean as explained below before inserting them into the port. EXFO is not responsible for damage or errors caused by bad fiber cleaning or handling.
Ensure that your patchcord has appropriate connectors. Joining mismatched connectors will damage the ferrules.
To connect the fiber-optic cable to the port:
1.Inspect the fiber using a fiber inspection microscope. If the fiber is clean, proceed to connecting it to the port. If the fiber is dirty, clean it as explained below.
2.Clean the fiber ends as follows:
2a. Gently wipe the fiber end with a lint-free swab dipped in isopropyl alcohol.
2b. Use compressed air to dry completely.
2c. Visually inspect the fiber end to ensure its cleanliness.
