ENGLISH
Installation
Television Location
Follow these recommendations before deciding the
location of your television.
• Avoid excessive sunlight or bright lights, including
reflections.
• Keep away from excessive heat or moisture. Inadequate
ventilation may cause internal component failure.
• Fluorescent lighting may reduce remote control
transmitting range.
• Keep away from magnetic equipment, including motors,
fans and external speakers.
WARNING: Use this television receiver 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. In order to
avoid injury to children, never place your television receiver on a
piece of furniture that is capable of being tilted by a child leaning
on it, pulling on it, standing on it, or climbing on it. A falling
television can cause serious injury or even death.  
Optional Cable Connections
Shielded audio and video cables should be used between
components. For best results:
• Use 75-ohm coaxial shielded cables.
• Use appropriate input and output connectors, that match
your component connectors.
• Avoid long cables to minimize interference.
AC Power Supply Cord

OVER, CRIMPED, BENT, OR PINCHED, PARTICULARLY AT PLUGS,
CONVENIENCE RECEPTACLES, AND THE POINT WHERE THEY EXIT
FROM THE APPARATUS.

cable company. 
Note:A cable converter box may be
required for proper reception.

company for compatibility
requirements.
Antenna Connection
• For proper reception of VHF/
UHF channels, an external
antenna is required. For best
reception an outdoor antenna
is recommended.

WARNING: The marking or retained image on the
picture tube resulting from viewing fixed image is
not an operating defect and as such is not covered
by Warranty. 
This television is designed to display constantly
moving images on the screen. Continuous viewing of
stationary images such as letterbox pictures on
standard screen TVs (with top/bottom bars), non-
expanded standard (4:3) pictures on wide screen TVs
(with side bars shown on each side of an image), stock
market report bars (ticker running at the bottom of the
screen), video game patterns, fixed scoreboards,
bright station logos, on-line (Internet) or repetitive
computer style patterns should be limited.
The extended use of fixed image program material can
cause a permanent picture tube damage, shown as a
“shadow image” viewable on normal programs. This
type of irreversible picture tube deterioration can be
limited by performing the following steps:
• Do not display the fixed image for extended periods
of  time.
• Turn the power off when not in use.
