This equipment has been tested and found to comply with the limits for a
Class
B digital device,pursuant to Part 15 of FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in
a residential installation.This equipment generates, uses, and can radiate
frequency energy and, if not installed and used in accordance with
instruction manual, may cause harmful interference to radio
communications. However, there are no guarantees that interference
to
radio interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment
off and on,
the user is encouraged
to try to correct the interference by one ormore of
the following measures:
Reorient orrelocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
Consult the dealer or an experienced radioITV technician for help.

WARNING
Changes or modifications not expressly approved by EXFO Electro-
Optical Engineering could void the user's authority to operate the
equipment.
In a 3 Vlm radiated field (26-1000 MHz, 80% AM modulation with a 1
kHz sine wave) or with a conducted RF field of 3 V (0.15-100 MHz,
80% AM modulation with a 1 kHz sine wave), readings may vary by
+0.
