End-of-life product recycling
Grass Valley’s innovation and excellence in product design also extends to the programs we’ve
established to manage the recycling of our products. Grass Valley has developed a
comprehensive end-of-life product take back program for recycle or disposal of end-of-life
products. Our program meets the requirements of the European Union’s WEEE Directive and
in the United States from the Environmental Protection Agency, individual state or local
agencies.
Grass Valley’s end-of-life product take back program assures proper disposal by use of Best
Available Technology. This program accepts any Grass Valley branded equipment. Upon
request, a Certificate of Recycling or a Certificate of Destruction, depending on the ultimate
disposition of the product, can be sent to the requester.
Grass Valley will be responsible for all costs associated with recycling and disposal, including
freight, however you are responsible for the removal of the equipment from your facility and
packing the equipment ready for pickup.
For further information on the Grass Valley product take back system please contact Grass
Valley at + 800 80 80 20 20 or [phone] from most other countries. In the US and
Canada please call 800-547-8949 or 530-478-4148. Ask to be connected to the EH&S
Department. In addition, information concerning the program can be found at:

Important information
Read these instructions carefully and retain them for future reference.
During installation and operation of this equipment, local building safety and fire protection
standards must be observed.
Before connecting the equipment to the power supply of the installation, verify the proper
functioning of the protective earth lead.
Whenever it is likely that safe operation is impaired, the apparatus must be made inoperative
and secured against any unintended operation. The appropriate servicing authority must then
be informed. For example, safety is likely to be impaired if the apparatus fails to perform the
intended function or shows visible damage.
Any changes or modifications not expressly approved in this manual could void your authority
to operate this equipment.
Cautions and Warnings
Read and comply with the warning and caution notices that appear in the manual.
– Warnings indicate danger that requires correct procedures or practices to prevent
death or injury to personnel.
– Cautions indicate procedures or practices that should be followed to prevent damage
or destruction to equipment or property.

Warnings
To prevent fire or shock hazard, do not expose the unit to rain or moisture. If the unit is in a wet
or damp environment, a rain cover must be used to protect it for personal safety reasons
(EN60065). The rain cover supplied with the unit protects it according to safety specification
EN60529 up to level IPX2 (spraying water).
To avoid electrical shock, do not remove covers or panels. Refer servicing to qualified
personnel only.
In case of an emergency ensure that the power is disconnected.
Use only fuses of the type and rating specified.
Connect the product only to a power source with the specified voltage rating.
The Base Station must always be connected to protective earth. Do not interrupt the
protection conductor inside or outside the unit. Do not disconnect the protective earth
terminal. Intentional interruption is prohibited and is likely to make the unit dangerous.
To prevent risk of overheating, ventilate the units correctly.
For safety reasons the Base Station must be mounted in a 19-inch rack which has safety covers
according to IEC65. When two Base Stations are mounted above each other, the minimum
distance between them must be 50mm or the rack must be force-air cooled.

Triax cable systems
Only connect a Triax cable from the same LDK camera family to the unit.
Do not allow system earth currents to exceed 1.5A in the outer shield of the Triax cable or 0.2A
in other cable shields.
To avoid excessive earth currents in a Triax system, galvanically separate the power earth
connection of equipment connected to the camera from the camera earth.
It is strictly prohibited to short circuit the inner and outer shields of a Triax cable used to
connect a camera to a base station.
Galvanic separation
Because of the nature of Triax systems, with long distances between camera and Base
Station, the risk of earth currents flowing is greater. These earth currents can result in damage
to the equipment.
For example, a monitor connected directly to the CVBS output of the camera is powered
locally. The earthing point of the monitor’s power supply can be at a different potential with
respect to the earthing point of the Base Station. If the power earth of the monitor is also the
video earth, then this earth potential is transferred to the camera via the shield of the BNC
connector. The difference in earth potential between the camera and the Base Station results
in an earth current in the Triax system.
To prevent earth currents from flowing in the Triax system, we recommend galvanic separation
of earthed equipment connected to the camera. This separation can be achieved by using an
isolation transformer between the local power outlet and the equipment connected to the
camera. Alternatively, use equipment that has a double insulation and therefore does not
require an earth connection.

Fiber optic transmission units
The CLASS 1 LASER PRODUCT label is located on top of the fiber optic connector on the rear
panel.
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.
