radio communications. However, there is no 
guarantee that interference will not occur in a 
particular installation. If this equipment does 
cause harmful interference to radio or television 
reception, which can be determined by turning 
the equipment off and on, the user is encour-
aged to try to correct the interference by one or 
more of the following measures:
- Reorient or relocate the receiving antenna.
-  Increase the separation between the equip-
ment and receiver.
-  Connect the equipment to an outlet on a circuit 
different from that to which the receiver is con-
nected.
-  Consult the dealer or an experienced radio/TV 
technician for help.
This device complies with part 15 of the FCC Rules.
Operation is subject to the following two condi-
tions: (1) This device may not cause (harmful) 
interference, and (2) this device must accept 
any interference received, including interference 
that may cause undesired operation (of the 
device).
Any changes or modifications in construction of 
this device which are not expressly approved by 
the party responsible for compliance could void

IMPORTANT INFORMATION TO PREVENT “IMAGE 
BURN / BURN-IN” ON YOUR TV SCREEN
ꔛ When a fixed image (e.g. logos, screen menus, video game, and computer display) is displayed on 
the TV for an extended period, it can become permanently imprinted on the screen. This phenom-
enon is known as “image burn” or “burn-in.” Image burn is not covered under the manufacturer’s 
warranty. 
ꔛ In order to prevent image burn, avoid displaying a fixed image on your TV screen for a prolonged 
period (2 or more hours for LCD, 1 or more 
hours for Plasma). 
ꔛ Image burn can also occur on the letter-
boxed areas of your TV if you use the 4:3 
aspect ratio setting for an extended period.

SAFETY INSTRUCTIONS
IMPORTANT SAFETY INSTRUCTIONS
Read these instructions.
Keep these instructions.
Heed all warnings.
Follow all instructions.
1Do not use this apparatus near water.
2Clean only with dry cloth.
3Do not block any ventilation openings. Install in 
accordance with the ma nufacturer’s instruc-
tions.
4Do not install near any heat sources such as 
radiators, heat registers, stoves, or other appa-
ratus (including amplifiers) that produce heat.
5Do 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 blade or the third 
prong are provided for your safety. If the provided 
plug does not fit into your outlet, consult an elec-
trician for replacement of the obsolete outlet.
6Protect the power cord from being walked 
on or pinched particularly at plugs, conve-
nience receptacles, and the point where 
they exit from the apparatus.
7Only use attachments/accessories speci-
fied by the manufacturer.
8Use 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.
   
9Unplug this apparatus during lighting 
storms or when unused for long periods 
of time.
10Refer all servicing to qualified service per-
sonnel. Servicing is required when the 
apparatus has been damaged in any way, 
such as power-supply cord or plug is dam-
aged, liquid has been spilled or objects

11Never touch this apparatus or antenna during 
a thunder or lighting storm. 
12When mounting a TV on the wall, make sure 
not to install the TV by the hanging power 
and signal cables on the back of the TV.
13Do not allow an impact shock or any objects 
to fall into the product, and do not drop onto 
the screen with something.
14CAUTION concerning the Power Cord:
It is recommend that appliances be placed 
upon a dedicated circuit; that is, a single 
outlet circuit which powers only that appli-
ance and has no additional outlets or 
branch circuits. Check the specification page 
of this owner's manual to be certain.
Do not connect too many appliances to the 
same AC power outlet as this could result in 
fire or electric shock.
Do not overload wall outlets. Overloaded wall 
outlets, loose or damaged wall outlets, exten-
sion cords, frayed power cords, or damaged 
or cracked wire insulation are dangerous . Any 
of these conditions could result in electric 
shock or fire. Periodically examine the cord of 
your appliance, and if its appearance indicates 
damage or deterioration, unplug it, discon-
tinue use of the appliance, and have the cord 
replaced with an exact replacement part by 
an authorized servicer. Protect the power cord 
from physical or mechanical abuse, such as 
being twisted, kinked, pinched, closed in a 
door, or walked upon. Pay particular attention 
to plugs, wall outlets, and the point where the 
cord exits the appliance. 
Do not use a damaged or loose power cord. 
Do not pull on the power cord to unplug the 
TV. Grasp the plug when unplugging the 
power cord.
15WARNING - To reduce the risk of fire or elec-
trical shock, do not expose this product to 
rain, moisture or other liquids. Do not touch 
the TV with wet hands. Do not install this 
product near flammable objects such as 
gasoline or candles or expose the TV to 
direct air conditioning.

do not place objects filled with liquids, such 
as vases, cups, etc. on or over the appara-
tus (e.g. on shelves above the unit).
17GROUNDING
Ensure that you connect the earth ground 
wire to prevent possible electric shock (i.e. a 
TV with a three-prong grounded AC plug 
must be connected to a three-prong ground-
ed AC outlet). If grounding methods are not 
possible, have a qualified electrician install a 
separate circuit breaker.  
Do not try to ground the unit by connecting it 
to telephone wires, lightening rods, or gas 
pipes.

20ANTENNAS
Outdoor antenna grounding
If an outdoor antenna is installed, follow the 
precautions below. An outdoor antenna sys-
tem should not be located in the vicinity of 
overhead power lines or other electric light or 
power circuits, or where it can come in contact 
with such power lines or circuits as death or 
serious injury can occur.
Be sure the antenna system is grounded so as 
to provide some protection against voltage 
surges and built-up static charges. 
Section 810 of the National Electrical Code 
(NEC) in the U.S.A. provides information with 
respect to proper grounding of the mast and 
supporting structure, grounding of the lead-in 
wire to an antenna discharge unit, size of 
grounding conductors, location of antenna 
discharge unit, connection to grounding elec-
trodes and requirements for the grounding 
electrode.
