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.
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.

TO CATV INSTALLER
This reminder is provided to call the CATV system installer's attention
to Article 820-40 of the National Electrical Code (NEC) that provides
guidelines for proper grounding, and in particular, specifies that the
cable ground shall be connected to the grounding system of the
building, as close to the point of entry as practical.
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 goes out when the apparatus is turned off ,
regardless of whether it is still plugged into an AC power
source.
Eliminate AC Power/Mains
Overloads
WARNING: Avoid electric shock
and fi re hazard! Do not overload AC power/
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.
