Only use attachments/accessories specified by the manufacturer.
12)
Use only with the cart, stand, tripod, bracket, or table specified by the
manufacturer, or sold with the apparatus. When a cart is used, use caution
when moving the cart/apparatus combination to avoid injury from
tip-over.
13)
Unplug this apparatus during lightning storms or when unused for long periods of
time.
14)
Refer all servicing to qualified service personnel. Servicing is required when the
apparatus has been damaged in any way, such as a power-supply cord or plug is
damaged, liquid has been spilled or objects have fallen into the apparatus, the
apparatus has been exposed to rain or moisture, does not operate normally, or has
been dropped.
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 fire 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 fire 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.
