Packing/Unpacking
Inspect the shipping container for evidence of damage immediately after receipt. If
the shipping container or cushioning material is damaged, it should be kept until the
contents of the shipment have been checked for completeness and the unit has
been checked mechanically and electrically.
The shipping container should be placed upright and opened from the top. Remove
the cushioning material and lift out the contents.
The contents of the shipment should be checked against the packing list. If the
contents are incomplete, if there is mechanical damage or defect, or if the unit does
not perform correctly when unpacked, notify your Grass Valley sales or service
centre within eight days.
If the shipping container shows signs of damage or stress, notify the carrier as well.
If the unit is being returned to Grass Valley for servicing, try to use the containers
and materials of the original packaging. Attach a tag indicating the type of service
required, return address, model number, full serial number and the return number
which will be supplied by your Grass Valley service centre.
If the original packing can no longer be used, the following general instructions
should be used for repacking with commercially available materials:
• Wrap unit in heavy paper or plastic.
• Use a strong shipping container.
• Use a layer of shock-absorbing material around all sides of the unit to provide
firm cushioning and prevent movement inside container.
• Seal shipping container securely.
• Mark shipping container FRAGILE to ensure careful handling.

Fiber-optic transmission units
CLASS 1
LASER PRODUCT
LASER KLASSE 1
PRODUKT
Laser safety statement (Europe)
Fiber-optic transmission units are classified as a “CLASS 1 Laser Product” according
to EN 60825-1, Safety of Laser products. Class 1 laser products are considered safe
and do not result in biological hazard if used according to the instructions.
Laser safety statement (US)
Fiber-optic transmission units are classified as a “CLASS 1 Laser Product” according
to 21CFR 1040.10 of the US Food and Drug Administration (FDA) Center for Devices
and Radiological Health.
Use of controls, adjustments or performance of procedures other than those
specified herein may result in hazardous radiation exposure.
To ensure proper use of this product, please read this instruction manual carefully
and retain for future reference. Should the unit ever require maintenance, contact an
authorized service location.
Fiber-optic cable precautions
Fiber-optic cables and connectors are easily damaged; take the following
percautions into account:
– Do not bend the cable beyond the minimum permissible bend range
specified for the cable.
– Avoid kinks in the cable.
– Avoid subjecting the cable to a high tension force (even momentarily).
– Do not twist the cable when connecting it to equipment.
– Insert connectors straight and fully into their corresponding sockets.
– In fiber-optic cable systems always put the dust caps on cable and panel
connectors immediately after disconnecting a cable. Keep the dust caps
clean.

Cleaning fiber-optic connectors
Warning
Never clean an optical connector attached to a fiber that is carrying light.
Particles of foreign matter on the tip of a ferrule can have a disabling effect on fiberoptic transmission. Fiber-optic connectors need to be cleaned every time they are
mated and unmated; it is essential that fiber-optic users develop the necessary
discipline to always clean the connectors before they are mated.
Use a commerially available cleaning kit specifically designed for fiber-optic
connectors and follow the manufacturer's instructions carefully.
• The connector sections to be cleaned include the tips and sides of ferrules, the
interior walls of alignment sleeves, and the interior and exterior of connector
shells.
• For plugs, the interior surfaces of alignment sleeves and the tips of ferrules are
to be cleaned with a cleaning stick treated with the appropriate fluid. (Cleaning
sticks with a slender design are available that allow alignment sleeves to be
cleaned without having to detach them.)
• For jacks, it is important to clean both the tips and sides of the completely
protruding ferrules.
• Both the male and female connector shells tend to attract dust and metal
particles, so it is important to clean both the insides and outsides.
• The fiber end face and ferrule must be absolutely clean before it is inserted
into a transmitter or receiver.
• Mate the connector immediately! Don't let the connector lie around and
collect dust before mating.
• Air can be used to remove lint or loose dust from the port of a transmitter or
receiver to be mated with the connector. Never insert any liquid into the ports.
