Installing the tuner box
Important safety precautions
Before installing the tuner box, pay
attention to the following to ensure the
safety of installation:
• Wear suitable insulation gloves to
prevent any possibilities of injuries.
• Be sure to turn the display power off and
disconnect the power cord from the power
outlet. Turn the power of the devices off

IMP1.0A LA 5
and remove all connected signal cables if
the display is connected to other devices.
• Make sure that there is sufficient space
around the display for performing the
installation. If not, it is suggested that you
move the display to a suitable place to
perform installation, and then move it back
to its original location when installation is
completed.
Installing the tuner box
1. Locate the tuner box slot on the left side
ofthe display (as shown in the illustration).
2. Remove the protective film on the tuner
box and then insert it into the slot. Pay
attention to the direction of the tuner box
when inserting.
3. Push the tuner box all the way into the
slot.
4. Use the supplied screw and a suitable
scrsewdriver to secure the tuner box on
the display.
5. Connect the cable or aerial antenna
cable to the connector on the tuner box.
Follow the instructions of "Searching and
storing channels" on page 22 to scan and
store the channels available in your area.

IMP1.0A LA 6
Making connections
Pay attention to the following when
making connections:
• Before connecting any devices, please
turn all equipment off.
• To obtain the most benefit from the
digital LCD screen, you should select the
connection method which will provide you
with the best possible signal.
• Do not pull cables out of sockets by
grasping the cable itself, as you may
damage the cable. Only ever remove
cables from sockets by grasping the plug
on the end of the cable.
• Once connected, please ensure that all
plugs are fully inserted and firmly seated.
Be aware that if incorrect connections are
made, picture quality may be adversely
affected.
Connecting the Composite Video input
Connect the Composite Video output of
your output equipment to the VIDEO and
AUDIO L/R terminals on the display using
the Composite Video cable as illustrated.
A Composite Video cable consists of three
connectors: Yellow (video), White (left
channel audio), and Red (right channel
audio). Ensure that the colors of the plugs
and terminals match when making
connection. To view video image from this
input, switch the input source to AV.
Composite Video provides the least
optimal image quality. Both S-Video and
Component Video provide better quality
video signals. AV supports both
Composite Video and SVideo signal
inputs. If you use S-Video, you cannot use
Composite Video for that input.
Connecting the S-Video input
1. Connect the S-Video output of your
output equipment to the display's
S-VIDEO terminal using an S-Video cable
(not provided). Pay attention to the
alignment of the plugs on the S-Video
cable when inserting so as not to damage
any pins.

IMP1.0A LA 7
2. Connect the corresponding audio
output of the output equipment to the
AUDIO L/R input terminals using a
suitable audio cable.
To view video image from this input,
switch the input source to AV.
You should not connect both a composite
Video and an S-Video from the same
device; just one or the other. If you have
the choice, use the S-Video instead of
composite Video as an S-video signal
provides a higher quality signal to that of
composite Video.
Connecting the Component Video input
1. Connect the S-Video output of your
output equipment to the display's
S-VIDEO terminal using an S-Video cable
(not provided). Pay attention to the
alignment of the plugs on the S-Video
cable when inserting so as not to damage
any pins. 2. Connect the corresponding
audio output of the output equipment to
the AUDIO L/R input terminals using a
suitable audio cable.
To view video image from this input,
switch the input source to AV.
You should not connect both a
composite Video and an S-Video from
the same device; just one or the other.
If you have the choice, use the S-Video
instead of composite Video as an
S-video signal provides a higher
quality signal to that of composite
Video.
1. Connect the Component Video output
of your output equipment to the display's Y,
CB/PB and CR/PR terminals using a
Component Video cable (not provided). A
Component Video cable consists of three
plugs: Green (Y), Blue (CB/PB), and Red
(CR/PR). Ensure that the colours of the
plugs and terminals match when making
connection.
2. Connect the corresponding audio
output of your output equipment to the
AUDIO L/R input terminals on the display
using an audio cable (not provided).
To view video image from this input,
switch the input source to Component.
Of the analog video signal types,
Component Video offers the best
quality.

IMP1.0A LA 8
Connecting the DVI input
1. Connect the digital video output of your
output equipment (for example, a PC or
digital Set Top Box) to the HDMI terminal
on the display using a DVI to HDMI
adaptor cable (not provided).
2. Connect the DVI audio output of your
output equipment to the display's
DVIAUDIO L/R input terminals using an
appropriate audio cable (not provided). To
view video image from this input, switch
the input source to HDMI.
When connected to a PC, you should
adjust the resolution in the display
properties of the computer to closely
match the native resolution of the display
(for example, 1360 x 768 pixels).
Connecting the HDMI input
Connect the HDMI output of your output
equipment to the HDMI terminal on the
display using an HDMI cable (not
provided). To view video image from this
input, switch the input source to HDMI.
HDMI (High-Definition Multimedia
Interface) is an uncompressed and
all-digital audio/video interface. HDMI
provides an interface between any
audio/video source, such as a set-top box,
DVD player, or A/V receiver over a single
cable. The display’s HDMI inputs are
compliant with the HDMI 1.2 standard.
However, the playback of SACD (Super
Audio CD) audio is not supported. Be
aware that HDMI input must be HDCP
compliant to be displayed. To ensure the
stability and performance of signal
transmission, it is recommended that you

IMP1.0A LA 9
use high-quality and HDMI-certified cable
for connection.
Connecting the stereo audio output
This display provides a set of stereo audio
output terminals (RCA type) for delivering
the audio signal to a sound system or
other audio devices. Connect the audio
input terminals of an amplifier or other
audio device to the AUDIO OUT L/R
terminals on the display using a suitable
audio cable.
This output is always available. Its level is
fixed and cannot be adjusted by the
Volume setting of the display.
Installing the tuner box
Before installing the tuner box, please pay
attention to the following to ensure the
safety of installation:
• Wear suitable protective insulation
gloves to prevent any possibilities of
injuries.
• Peel off the protective film on the tuner
box prior to installation.
• Be sure to turn the display power off and
disconnect the power cord from the power
outlet. Turn the power of the devices off
and remove all connected signal cables if
the display is connected to other devices.
• Make sure that there is sufficient space
around the display for performing the
installation. If not, it is suggested that you
move the display to a suitable place to
perform installation, and then move it back
to its original location when installation is

IMP1.0A LA 10
completed.
1. Turn the display to reveal its left side
and locate the tuner box slot (as shown in
the illustration on the right).
2. Use a suitable screwdriver to remove
the screw that secures the tuner box slot
cover.
3. Remove the tuner box slot cover as
shown.
4. Peel off the protective film on the tuner
box and then insert the tuner box into the
slot as shown. Pay attention to the
direction of the tuner box when inserting.
5. Push the tuner box all the way into the
slot.
6. Use the supplied screw and a suitable
screwdriver to secure the tuner box on the
display.
7. There are two connectors on the tuner
box: one for aerial antenna input and the

IMP1.0A LA 11
other for loop-through output of signals to
other devices.
Connect the aerial antenna (to be
purchased separately) cable to the aerial
antenna input connector. If necessary, you
can also connect other devices to the
loop-through output connector.
