Certification Information

Federal Communications Commission (FCC) and Industry
Canada Information

Electronic test and measurement equipment is exempt from FCC part 15, subpart B
compliance in the United States of America and from ICES-003 compliance in
Canada. However, EXFO Inc. makes reasonable efforts to ensure compliance to the
applicable standards.

The limits set by these standards are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the user guide, may cause
harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.

Modifications not expressly approved by the manufacturer could void the user's
authority to operate the equipment.

 Information

Electronic test equipment is subject to the EMC Directive in the European Union.
The IEC 61326-1 standard prescribes both emission and immunity requirements for
laboratory, measurement, and control equipment. This unit has undergone
extensive testing according to the European Union Directive and Standards.

Laser Safety Information (FLS-300 and FOT-300)

WARNING

Use of controls, adjustments and procedures for operation and
maintenance other than those specified herein may result in
hazardous radiation exposure.

WARNING

Do not install or terminate fibers while a laser source is active. Never
look directly into a live fiber and ensure that your eyes are protected
at all times.

Turning the Unit On and Off

When you turn off the FPM-300 or the FOT-300, it saves the current wavelength, unit
and reference power.

IMPORTANT

If you remove batteries (and the AC adapter is unplugged), the unit
will turn off without saving the above values.

If batteries are low (and the AC adapter is unplugged), the unit will
save the above values and turn off.

Note: Offset nulling values are always returned to factory settings.

To turn on the unit:

Press . The unit displays EXFO Inc. for a few seconds. You may use it
immediately under normal conditions.

To turn off the unit:

From normal operating mode (that is, not FAV or PREF), hold down a few
seconds.

Activating Automatic Shutdown (Auto-Off)

When auto-off is activated, the unit will turn off after
10 minutes of idle time.

Auto-off is activated by default when you turn on the
unit.

To deactivate/reactivate auto-off:

When unit is on, press .

Installing the EXFO Universal Interface (EUI)

The EUI fixed baseplate is available for connectors with angled (APC) or non-angled
(UPC) polishing. A green border around the baseplate indicates that it is for
APC-type connectors.

To install an EUI connector adapter onto the EUI baseplate:

1. Hold the EUI connector adapter so the dust cap opens downwards.

2. Close the dust cap in order to hold the connector adapter more firmly.

3. Insert the connector adapter into the baseplate.

4. While pushing firmly, turn the connector adapter clockwise on the baseplate to

lock it in place.
