Non-Use Period
During extended periods when the device is not used,
unplug it from the power source and retract the power-cord.
Grounding or Polarization
•
Polarized
If this product is equipped with a polarized alternating
current line plug (a plug having one blade wider than the
other), it will fit into the outlet only one way. This is a safety
feature. If you are unable to insert the plug fully into the
outlet, try reversing the plug. If the plug should still fail to
fit, contact your electrician to replace your obsolete outlet.
Do not defeat the safety purpose of the polarized plug.
•
Grounded
If this product is equipped with a three-wire grounding type
plug, a plug having a third (grounding) pin, it will only fit
into a grounding type power outlet. This is a safety feature.
If you are unable to insert the plug into the outlet, contact
your electrician to replace your obsolete outlet. Do not
defeat the safety purpose of the grounding type plug.
Outdoor Antenna Grounding
If an outside antenna or
cable system is connected
to the FS-4 HD/Pro HD,
verify that the antenna or
cable system is
grounded. This provides
some protection against
voltage surges and built-
up static charges.
Refer to Article 810 of the
National Electric Code, ANSI/NFPA 70, for information about
the proper grounding of the mast and supporting structure,
grounding of the lead-in wire to an antenna discharge unit, size
of grounding connectors, location of antenna discharge unit,
connection to grounding electrodes, and requirements for the
grounding electrode.
Lightning and Power Surges
During electrical storms or when left unattended and unused for
long periods of time, unplug the FS-4 HD or FS-4Pro HD from
the power source and disconnect the antenna or cable system.
