2.1 Check list
The box for your TFT-721 should contain the following
items:
zThe TFT-721
zOwner’s manual
zRemote control
zVideo output cable
zHeadphone
zPower supply adapter (AC adapter)
zUpgrade cable
zCar Power Adapter
zAccessorial Antenna
2.2 About transmission
Buildings, mountains and the surrounding terrain can
block Radio and TV signals. Depending on whether the
receiver is located in a valley, behind a mountain or in a
concrete building, the quality of reception may vary
considerably. As with most other transmissions, bad
weather affects reception quality. We recommend use the
accessorial long antenna instead of short antenna when
the signal isn’t good, but not allow using other model
antennas.
2.3 About the portable receiving antenna and
accessorial antenna
zUse the antenna for UHF channels 21-69 for DVB-T,
such as a directional antenna.
zIf possible, place the antenna by the window and
directed towards the TV transmitter.
zThe strength of TV signal varies according to
reflections from buildings or mountains. The signal
penetrates thick stone or concrete walls poorly.
However, a wooden building is not a big barrier to
digital TV signals.
2.4 Connecting the TFT-721 to the TV
zConnect the TFT-721 CVBS jack to the TV CVBS
input socket for video.
zConnect the TFT-721 Headphone jack to the TV
audio input socket for sound.

Heat sources, such as radiators or air ducts,
10
3. Direct sunlight, Excessive dust, Moisture or rain,
Mechanical vibration or shock, Strong magnets or
speakers that are not magnetically shielded, Ambient
temperature of more than 35
oC or less than 5
oC and
High humidity.
4. Do not place electronic equipment near the TFT-721.
The electromagnetic field of the TFT-721 may cause
a malfunction.
5. Provide adequate air circulation to prevent internal
heat from building up. Do not place the TFT-721 on
porous surfaces such as rugs or blankets, or near
material such as curtains or draperies that may block
its ventilation slots.
6. The TFT-721 uses high-frequency radio signals and
may cause interference to radio or TV reception. If
this occurs, relocate the TFT-721 a suitable distance
away from the set.
7. Use only specified peripheral equipment and interface
cables; otherwise, problems may occur.
8. Do not use cut or damaged connection cables.
9. If the TFT-721 is brought directly from a cold
location to a warm one, moisture may condense inside
the TFT-721, In this case, allow at least one hour
before turning on the TFT-721, If any problems occur,

and store safely in case use another day.
2. You may see tiny black points and/or bright points
(red, blue, or green) that continuously appear on the
LCD. LCD has a very few (0.01%) unlit pixels and
always lit pixels. You may also see distortion in
colours or brightness depending on your perspective.
This is a normal result of the manufacturing process
and does not indicate a malfunction.
3. The LCD is manufactured using high-precision
technology, do not apply a strong shock or drop it.
Do not disassemble or refit yourself.

do not apply any force to the LCD. If the liquid
leaves out, please use soap and clean water to clean.
9. If you bring your LCD from a cold location to a
warm one, moisture may condense on the LCD. In
such a case, wipe off the moisture before using your
LCD. It is recommended to use tissue papers to wipe
off the moisture. If the LCD surface is still not warm
enough, moisture may condense again. Leave LCD
until its surface is warmed up to the ambient
temperature. Do not use alcohol, gas or chemistry
reagent to wipe.
10. Close LCD after use or during in malfunction. Please
switch off power in case safe.
