DIGITAL TELEVISION TRANSITION NOTICE
This device contains a digital television tuner, so it should receive digital over the air
TV programming, with a suitable antenna, after the end of full-power analog TV
broadcasting in the United States on June 12, 2009. The nationwide switch to digital
television broadcasting will be complete on June 12, 2009, but your local television
stations may switch sooner. After the switch, analog-only television sets that receive
TV programming through an antenna will need a converter box to continue to receive
over-the-air TV. Watch your local stations to find out when they will turn off their
analog signal and switch to digital-only broadcasting.
For more information, call the FCC at 1-888-CALL-FCC (1-888-225-5322) or see
www.DTV.gov. For information on the TV Converter program, and on government
coupons that may be used toward the purchase of one, see www.dtv2009.gov, or call
the NTIA at 1-888-DTV-2009.
AVISO RELATIVO A LA TRANSICIÓN A TELEVISIÓN
DIGITAL
Este equipo incorpora un sintonizador de televisión digital, lo que le permitirá recibir
una programación digital televisada por aire, con una antena adecuada, cuando se
terminará la transmisión de alta potencia de la televisión analógica en los Estados
Unidos el 12 de Junio de 2009. Ciertos receptores de televisión antiguos, si
dependen de una antena de TV, necesitarán un conversor de TV para recibir por el
aire una programación digital, pero seguirán funcionando como antes para otros
usos (por ejemplo para ver emisoras de TV de baja potencia que todavía transmiten
en analógico, para ver películas pregrabadas, o para utilizar sus videojuegos).
Para obtener más información, llame FCC 1-888-CALL-FCC (1-888-225-5322) o
refiérase a www.DTV.gov. Para toda información sobre el programa de conversores
de TV, y acerca de los cupones del gobierno que se pueden usar para comprarlos,
refiérase a www.dtv2009.gov, o llame al NTIA al 1-888-DTV-2009.

ANTENNA INSTALLATION SAFETY
Outdoor Antenna Grounding
If an outside antenna or cable system is connected to the LED TV, be sure the
antenna or cable system is grounded to prevent voltage surges and built-up static
charges. Article 810 of the National Electrical Code, ANS/NFPA 70, provides
information on proper grounding of the mast and supporting structure, grounding of
the lead-in wire to an antenna discharge unit, connection to grounding electrodes,
and requirements for the grounding electrode.
Lightning
Power lines
For added protection for the LED TV during a lightning storm, or
when it is left unattended and unused for long periods of time,
unplug it from the wall outlet and disconnect the antenna or cable
system. DO NOT disconnect the antenna or the power cord during
a heavy storm—lightning may strike while you are holding the
cable cord, causing serious injury. Turn off the LED TV and wait for
the weather to improve.
An outside antenna system should not be located in the vicinity of
overhead power lines or other electric light or power circuits, or
where it can fall into such power lines or circuits. When installing an
outside antenna system, extreme care should be taken to keep
from touching such power lines or circuits as contact with them
might be fatal.
