Precautions

Choosing a location for your LCD TV

QTo Display your LCD TV on the included Pedestal Stand:

Observe the following safety precautions:

1)Place the TV on a sturdy, level surface that can support the weight of the TV.

2)Be sure to secure the TV to a wall, pillar, surface, or other immovable structure. To secure the TV in this manner, use the included strap located at the rear of pedestal stand. (see item 19, page 4).

Important notes about your LCD TV

The following symptoms are technical limitations of LCD Display technology and are not an indication of malfunction; therefore, Toshiba is not responsible for perceived defects resulting from these symptoms.

1)An after image (ghost) may appear on the screen if a fi xed, non-moving image is displayed for a long period of time. The after image is not permanent and will disappear in a short period of time.

2)The LCD panel contained in this TV is manufactured using an extremely high level of precision technology; however, there may be an occasional pixel (dot of light) that does not operate properly (does not light, remains constantly lit, etc.). This is a structural property of LCD technology, is not a sign of malfunction, and is not covered under your warranty. Such pixels are not visible when the picture is viewed from a normal viewing distance.

Note: Interactive video games that involve shooting a “gun” type of joystick at an on-screen target may not work on this TV.

Notes on handling

QDo not subject the LCD panel to physical shock, such as dropping it. It may cause unit damage and malfunction.

QWhen shipping the unit, the original shipping carton and packing materials come in handy. For fully protection, repack the unit as it was originally packed at the factory.

QDo not use volatile liquids, such as insecticide, near the unit.

Do not leave rubber or plastic products in contact with the unit for prolonged periods of time.

Doing so will leave marks on the fi nish.

QThe top and rear panels of the unit may become warm after a long period of use. This is not a malfunction.

QWhen the unit is not in use, always remove the disc and turn off the power.

Notes on locating the unit

QWhen you place this unit near a TV, radio, or VCR, the playback picture may become poor and the sound may be distorted. In this case, place the unit away from the TV, radio, or VCR.

QTo avoid damage to this product, never place or store the TV/DVD in direct sunlight; hot, humid areas; or areas subject to excessive dust or vibration.

Notes on moisture condensation

Moisture condensation damages the unit. Please read the following carefully.

Moisture condensation occurs, for example, when you pour a cold drink into a glass on a warm day and drops of water form on the outside of the glass. In the same way, moisture may condense on this unit·s internal optical pick-up lens, one of the most crucial internal parts of the unit.

Exampleeof moisture cond nsation!

Optical pick-up lens

Q Moisture condensation may occur in the following situations:

When you move the unit from a cold area to a warm area.

When you use the unit in a room in which the heat was just turned on.

When you use the unit in an area where cold air from an air conditioner directly hits the unit.

When you use the unit in a humid area.

QNever use the unit when moisture condensation may occur

Using the unit when moisture condensation exists may damage discs and internal parts. Connect the power cord of the unit to the wall outlet, turn on the unit, remove the disc, and leave it for two or three hours. After two or three hours, the unit will have warmed up and evaporated any moisture. Leaving the TV connected to the wall outlet will help prevent moisture condensation in the TV or DVD Player.

Wait!

About this owner·s manual

This owner·s manual explains the basic instructions of this unit. Some DVD video discs are produced in a manner that allows specific or limited operation during playback. As such, the unit may not respond to all operating command. This is not a defect in the unit. Refer to instruction notes of discs.

The following symbol may appear on the TV screen during operation.

It means that the operation is not permitted by the TV/DVD or the disc.

For example, sometimes it is unable to stop the playback of copyright message of the disc when the STOP (Q) button is pressed. Alternatively, this symbol may also indicate that the feature is not available for the disc.

Notes on region numbers

The region number of this unit is 1. If region numbers, which stand for their playable area, are printed on your DVD video disc and you do not fi nd 1 or ALL , disc playback will not be allowed by the player. (In this case, the unit will display a message on-screen.)

Some DVDs that have no region code label may still be subject to area restrictions and therefore not playable.
