1. Precautions ＆Notice
1.1 Safety Precautions
1) Cleaning: Unplug the power cord from the AC outlet before cleaning the
product. Use a damp cloth to clean the product. Do not use liquid cleaners
or aerosol cleaners.
2) Heat sources: Keep the product away from heat sources such as radiators,
heaters, stoves and other heat-generating products (including amplifiers).
3) For added protection for this television equipment 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. This will
prevent damage to the equipment due to lightning and power-line surges.
4) If an outside antenna is connected to the television equipment, be sure the
antenna system is grounded so as to provide some protection against
voltage surges.
Example of antenna grounding
as
p
er national electrical code
Antenna lead in wire
Ground clamp
Antena discharge unit
Grounding conductors
Electric service
equipment Ground clamps
Power service grounding
Electrode system unit
5) 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.
6) Ventilation-The vents and other openings in the cabinet are designed for
ventilation. Do not cover or block these vents and openings since
insufficient ventilation can cause overheating and/or shorten the life of
the product. Do not place the product on a bed, sofa, rug or other similar
surface, since they can block ventilation opening. This product is not
designed for built-in installation, do not place the product in an enclosed
place such as a bookcase or rack, unless proper ventilation is provided or
the manufacturer’s instructions are followed.
1.2 Product Safety Notice
1) Many electrical and mechanical parts in this chassis provide special
visual safety protection. The protection afforded by them cannot
necessarily be obtained by using replacement components rated for
higher voltage, wattage, etc.
2) Before replacing any of these components, read the parts list manual
carefully. The use of substitute replacement parts, which do not have the
same safety characteristics, as specified in the parts list may create shock,
fire or other hazards.
1.3 Service Notes
1) When replacing parts or circuit boards, wrap the wires around terminals
before soldering.
2) Keep wires away from high temperature components.
3) Keep cable and their shielding in their original position so as to reduce
interference.

3. Connection ＆Applications
Note:
! Audio out: The level of Audio O/P is constant. It won’t be affected by aligning volume, treble and
bass. This connecter should be connected to outer audio amplifier to enlarge the volume.
! Video O/P: When user wants to connect Audio and Video O/P of our LCD-TV to VCR for recording
program, the O/P has only one choice that is TV mode.
! Audio O/P: IF the main display is TV, the Audio O/P must be TV sound; otherwise, if sub display is
TV, the Audio I/P must be selected to “Sub”, so that the Audio O/P will be TV sound.
4. Controls Location
The buttons control your TV’s basic features, including the on-screen menu. To use the
more advanced features, you must use the remote control.
POWER: turn on or turn off the LCD TV.
SOURCE: set up the input source (PC, AV, SV, TV or CV.)
MENU: displaythemainmenu.
CHANNEL (down/up): change channels on sequence.
VOLUME (-/+): turn up or turn down the volume.
ASPECT RATIO: set up the ratio of display (Normal, Periscope, Zoom or Full.)
