(e.g. airbag, seat belt, etc.) that is fitted. It is advised that this product is installed in the rear of the vehicle only. Make sure that it is always securely fastened before use. Never place the product in a position where a sudden stop will cause it to become dislodged.

Ventilation

The TV must be well ventilated. Do not cover your TV or place it inside a small confined space. Make sure that there is a gap of at least 10cm on both sides and 20 cms at the top.

Interference

Do not place your TV on or near appliances which may cause electromagnetic interference (TV or Hi-Fi speakers). If you do, it may adversely affect the working of the unit, and cause a distorted picture or sound.

Screen Burn

A characteristic of Plasma and LCD TV Panels is that displaying the same image for a long time may cause a permanent after-image to remain on the screen. This is called screen burn. Most pictures shown on your TV will be constantly moving and fill the screen.

Examples of images that you need to watch out for are as follows (this is not an all-inclusive list): -Black Bars: If black bars appear at the left/right or top/bottom of the screen it is recommended to change the format so that the picture fills the entire screen.

-TV Channel Logos: e.g. Shopping channel logos and pricing displays - especially if they are bright and stationary. Moving or low-contrast graphics are less likely to cause ageing of the screen.

-PIP and Multipip: Do not view for long periods of time using the PIP or Multipip functions. -Time Displays

-Teletext: Do not view a stationary page for long periods of time.

-TV/DVD Menus: e.g. Listings of DVD disk content.

-Pause Mode: Do not leave the screen in pause mode for long periods of time, e.g. When watching DVDs or videos.

Note: To prevent screen burn if viewing any of the above for long periods of time, reduce contrast and brightness when viewing. Once burn-in occurs it will never disappear completely.

Batteries

Batteries are easily swallowed by young children. Do not allow young children to play with the remote control unit.

Covers

Do not remove any fixed covers as this may expose dangerous voltages.

Standby

The standby button on the remote control doesn't switch off the TV completely and the TV will continue to draw electricity from the mains supply. Therefore in the interests of safety and to avoid unnecessary energy consumption, never leave your TV in standby while unattended for long periods of time, eg. overnight, while on holiday or while out of the house.

Power Cord

Make sure your TV or TV stand is not resting on top of the power cord, as the weight of the TV may damage the cord and create a safety hazard. Make sure that the mains plug is easily accessible.

Packaging

If you can store the packaging it will prove useful should you need to transport the TV to protect it while it is in transit. Try to reuse packaging wherever you can. If you cannot store it, contact your local authority for details of your nearest recycling facilities.
