5)
Do not use this apparatus near water.
6) Clean only with dry cloth.
7) Do not block any ventilation openings. Install in accordance with the manufacturer's
instructions.
8) Do not install near any h
eat sources such as radiators, heat registers, stoves, or other
apparatus (including amplifiers) that produce heat.
9) Do not defeat the safety purpose of the polarized or grounding-type plug. A
polarized plug has two blades with one wider than the other. A grounding-type
plug has two blades and a third grounding prong. The wide bladeor the third
prong is provided for your safety. If the provided plug does not fit into your outlet,
consult an electrician for replacement of the obsolete outlet.
10)
Protect the power cord from being walked on or pinched particularly at plugs,
convenience receptacles, and the point where they exit from the apparatus.
11) 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 rainor moisture, does not operate normally, or has
been dropped.
Power SourceWarning
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 onthe 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.
Groundthe Product
WARNI NG: Avoid electric shock and fire ha za rd! If this product connects to coa xial
cable wiring, be sure the cable system is grounded (earthed). Grounding provides
some protection against voltage surges and built-up static charges.

IMPORTANT SAFETY INSTRUCTIONS
vi OL-29163-01
OutdoorGroundingSystem
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 a nd fir e ha za rd! Do not loca te a n outside a nte nna
system in the vicinity of overhead power lines or power circuits. Touching power lines
or circuits might be fatal.
Protect theProductfromLightning
In addition to disconnecting the AC power from the wall outlet, disconnect the signal inputs.
Verify the PowerSource fromtheOn/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.

IMPORTANT SAFETY INSTRUCTIONS
OL-29163-01 vii
