Power Source Warning
A label on this product indicates the correct power source for this
product. Operate this product only from an electrical outlet with the
voltage and frequency indicated on the product label. If you are
uncertain of the type of power supply to your home or business,
consult your service provider or your local power company.
The AC inlet on the unit must remain accessible and operable
at all times.
Ground the Product
WARNING: Avoid electric shock and fi re hazard!
If this product connects to coaxial cable wiring, be sure
the cable system is grounded (earthed). Grounding
provides some protection against voltage surges and
built-up static charges.
iv
Outdoor Grounding System
If this product connects to an outdoor antenna or cable system,
be sure the antenna or cable system is grounded (earthed).
This provides some protection against voltage surges and built-
up static charges.
Article 810 of the National Electric Code (NEC) ANSI/NFPA
No. 70-1990, provides the following information:
• Grounding of the mast and supporting structure
• Grounding the lead-in wire to an antenna discharge unit
• Size of the grounding conductors
• Location of the antenna-discharge unit
• Connection to grounding electrodes
• Requirements for the grounding electrodes (see the following
antenna grounding diagram as recommended by NEC ANSI/
NFPA 70)
WARNING: Avoid electric shock and fi re hazard!
Do not locate an outside antenna system in the vicinity
of overhead power lines or power circuits. Touching
power lines or circuits might be fatal.
Protect the Product from Lightning
In addition to disconnecting the AC power from the wall outlet,
disconnect the signal inputs.
Verify the Power Source from the On/Off
Power Light
When the on/off power light is not illuminated, the apparatus may
still be connected to the power source. The light may go out
when the apparatus is turned off, regardless of whether it is still
plugged into an AC power source.
Eliminate AC Mains Overloads
WARNING: Avoid electric shock and fi re hazard!
Do not overload AC mains, outlets, extension cords, or
integral convenience receptacles. For products that require
battery power or other power sources to operate them,
refer to the operating instructions for those products.
