User Guide
Optical Fiber Safety
Never look directly into the end of the optic fiber while either end of the system is
operating.
This CopperHead 3404 contains CDRH Class 1 laser devices. Always avoid looking directly
at, or staring into, the laser light located on an optical connector or on the end of a fiber. Eye
damage can result.
Infrared radiation is produced at the ST fiber connection and at the end of any un-
terminated optical fibers that are attached to this connection. Avoid any direct exposure to
the light that comes from these sources.
Do not power up the unit when no fiber is attached to the fiber port.
There are no user adjustments inside the CopperHead 3404. Do not attempt any type of
service to this instrument other than any as instructed this manual. Refer all servicing to
Grass Valley, a Belden Brand.
Always keep the Fiber Optical connectors protected. when not connected. Use protective
caps if available. This protects the connector from damage and the unlikely event of
exposure to an operating optical link. Keeping the connectors protected when the
connectors are not in use will prevent dirt and dust from entering the connector and
degrading the performance of the optical link.
Power Fuses
The CopperHead 3404 Base Station with internal power is equipped with Dual Cartridge
fuses located next to the AC Power receptacle at the left rear of the unit. Refer to

all times – both the AC Line Hot and the AC Line Neutral are fused.
