vi FS-C Portable DTE Recorder
• 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-C,
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.
