9 Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners

or aerosol cleaners. Use a damp cloth for cleaning.

10 Do not use this product near water.

11 Do not place this product on an unstable cart, stand or table. The product may fall,

sustaining serious damage.

12 Slots and openings are provided for ventilation; to ensure reliable operation of the

product and to protect it from overheating, these openings must not be blocked or
covered. This product should never be placed near or over a radiator or heat register
or in a built-in installation unless proper ventilation is provided.

13 This product should be operated from the type of power indicated on the marking

label. If you are not sure of the type of power available, consult your dealer or local
power company.

14 Do not allow anything to rest on the power cord. Do not locate this product where

the cord will be stepped on.

15 If an extension cord is used with this product, make sure that the total ampere rating

of the equipment plugged into the extension cord does not exceed the extension
cord ampere rating. Also, make sure that the total rating of all products plugged into
the wall outlet does not exceed the fuse rating.

18 Unplug this product from the wall outlet and refer servicing to qualified service

personnel under the following conditions:

a. When the power cord or plug is damaged or frayed.

b. If liquid has been spilled into the product.

c. If the product has been exposed to rain or water.

20 Do not overload an electrical AC outlet, power strip. The overall system load must not

exceed 80% of the branch circuit rating. If power strips are used, the load should not
exceed 80% of the power strip input rating.

21 Some products are equipped with a three-wire electrical grounding-type plug that

has a third pin for grounding. This plug only fits into a grounded electrical outlet. This
is a safety feature. Make sure the AC outlet is properly grounded. Do not defeat the
safety purpose of the grounding-type plug by trying to insert it

into a non-grounded
outlet. If you cannot insert the plug into the outlet, contact your electrician to replace the
outlet.

22 This LCD TV is designed for home entertainment and should not be used in working

environments. Maintain ample distance from it when watching: Sitting too close can strain
your eyes.

The grounding pin is an important safety feature. It is possible to receive an electric shock
from a system that is not properly grounded.

The grounding pin provides protection against unexpected noise and interference that is
produced by nearby electrical devices.

Default setting in different Empowering mode

Scenario mode in TV

Scenario has seven viewing modes designed to give you the best picture quality when
watching a particular kind of programme. There are seven audio and video settings for
optimal enjoyment of the following scenarios: Standard TV, Movie, Sport, Concert, Game,
NICE and User.

Pressing the Empowering Key will toggle between the different
modes.

Mode Information

Standard mode allows you to watch your favourite channels with sharp,

listen to clear-sounding audio.

For comfortably enjoying movies at home, Movie mode displays dim
scenes in clear detail; compensates for colour; and smoothly presents
motion images. This is accomplished through optimal Gamma correction
plus saturation, brightness and contrast adjustments. Movie mode makes
the most of high-definition movie soundtracks.

Sport mode is suited for outdoor sports programmes, with accurate
background depth and clear gradation between the bright, outdoor
playing field and darker auditoriums. Sports mode also brilliantly
enhances colours and presents swiftly moving pictures without residual
images. All of this is achieved via specific Gamma corrections and
saturation adjustments. Precise audio can be heard.

Concert mode places you in a virtual concert hall, opera house or

Game mode carefully details the exquisite graphics of modern video
games, providing lifelike entertainment while protecting your eyesight by
adjusting brightness and contrast. What's more, Game mode provides a
heightened audio experience.

NICE mode dynamically adjusts picture parameters according to the

Channel scan ordering

1. If your country supports ‘LCN’ (logical channel numbers)*, via Digital Channel
broadcasting, these channels will always have the highest priority.

2. If your country does not support DTV LCN, scanned channel numbers will start from
ch801 in order of frequency.

3. ATV channels will start from ch901, and follow the current ATV channel sorting rules.
If the highest DTV number is larger than 901, ATV channels will be sorted starting
from chX01 (X=10, 11…) depending on the LCN channel's digit count.

4. If there is any LCN conflict, either between ATV LCN and DTV LCN, the conflicting
channel will be stored in a channel location after ch800.

5. The TV will automatically detect new channels, and if a new channel is detected it will
place the LCN channel in its LCN position. If there's no LCN, or the channel position
has already been occupied, the channel will be located at the end of the non-LCN
channel list.

6. If there is no digital service after auto-scan, the analog channel may be located from
ch001. Referring to rule 3, the X in this case will be 0.

In some European countries, the TV broadcast will embed the LCN (logical channel
number) in the DTV signal to allocate a channel number.

Troubleshooting

Before you call the Acer service center, please check the following items:

Here is a list of possible situations that may arise during the use of your LCD TV. Easy
answers and solutions are provided for each.

There is no picture or sound.

• Make sure the power cord is properly inserted in the power outlet.

• Make sure the input mode is correctly set by your selected input.

• Make sure the antenna at the rear of the TV is properly connected.

• Make sure the main power switch is turned on.

• Make sure the volume is not set to minimum or the sound is not set to mute.

• Make sure the headphones are not connected.

Picture is not clear.

• Make sure the antenna cable is properly connected.

• Consider whether your TV signal is being properly received.

• Poor picture quality can occur due to a VHS camera, camcorder, or other peripheral
being connected at the same time. Switch off one of the other peripherals.

• The 'ghost' or double image may be caused by obstruction to the antenna due to
high-rise buildings or hills. Using a highly directional antenna may improve the
picture quality.

• The horizontal dotted lines shown on the pictures may be caused by electrical
interference, e.g., hair dryer, nearby neon lights, etc. Turn off or remove these.

English

Picture is too dark, too light or tinted.

• Check the colour adjustment.

• Check the brightness setting.

• Check the sharpness function.

• The fluorescent lamp may have reached the end of its service life.

Remote control does not work.

• Check the batteries of the remote control.

• Make sure the remote sensor window is not under strong fluorescent lighting.

• Try to clean the remote control sensor lens on the TV with a soft cloth.

• Use the buttons (hotkeys) on the TV before the remote control works.

If the above suggestions do not solve your technical issue, please refer to the warranty
card for service information.
