Important Safety Notice

Read and understand all instructions before you use your TV. If damage is caused by failure to follow instructions,

the warranty does not apply.

Safety

yRisk of electric shock or fire!

¾Never expose the TV to rain or water. Never place liquid containers. Such as vases, near the TV. If liquids

are spilt on or into the TV, disconnect the TV from the power outlet immediately. Contact Philips Consumer

Care to have the TV checked before use.

¾Never place the TV, remote control or batteries near naked flames or other heat source, including direct

sunlight. To prevent the spread of fire, keep candles or other flames away from the TV, remote control and

batteries at all time.

¾Never insert objects into the ventilation slots or other openings on the TV.

¾When the TV is swiveled ensure that no strain is exerted on the power cord. Strain on the power cord can

loosen connections and cause arcing.

yRisk of short circuit or fire!

¾Never expose the remote control or batteries to rain, water or excessive heat.

¾Avoid force coming onto power plugs. Loose power plugs can cause arcing or fire.

yRisk of injury or damage to the TV!

¾Two people are required to lift and carry a TV that weights more than 25 kg.

¾When stand mounting the TV, use only the supplied stand. Secure the stand to the TV tightly. Place the TV

on a flat, level surface that can support the combined weight of the TV and stand.

¾When wall mounting the TV, use only a wall mount that can support the weight of the TV. Secure the wall

mount to a wall can support the combined weight of the TV and wall mount. Koninklijke Philips Electronics

N.V. bears on responsibility for improper wall mounting that result in accident, injury or damage.

yRisk of injury to children! Follow these precautions to prevent the TV from toppling over and causing injury to

children:

¾Never place the TV on a surface covered by a cloth or other material that can be pulled away.

¾Ensure that no part of the TV hangs over the edge of the surface.

¾Never place the TV on tall furniture (such as a bookcase) without anchoring both the furniture and TV to the

wall or a suitable support

¾Educate children about the dangers of climbing on furniture to reach the TV.

yRisk of overheating! Never install the TV in a confined space. Always leave a space of at least 4 inches around

the TV for ventilation. Ensure curtains or other objects never cover the ventilation slots on the TV.

yRisk of damage to the TV! Before you connect the TV to the power outlet, ensure that the power voltage

matches the value printed on the back of the TV. Never connect the TV to the power outlet if the voltage is

different.

yRisk of injury, fire or power cord damage! Never place the TV or any objects on the power cord.

Meridian 1

yTo easily disconnect the TV power cord from the power outlet, ensure that you have full access to the power

cord at all times.

yWhen you disconnect the power cord, always pull the plug, never the cable.

yDisconnect the TV from the power outlet and aerial before lightning storms. During lightning storms, never touch

any part of the TV, power cord or aerial cable.

yRisk of hearing damage! Avoid using earphones or headphones at high volumes or for prolonged periods of

time.

yIf the TV is transported in temperatures below 5℃, unpack the TV and wait until the TV temperature matches

room temperature before connecting the TV to the power outlet.

Screen Care

yAvoid stationary images as much as possible. Stationary images are images that remain on-screen for

extended periods of time. Examples include: on-screen menus, black bars and time displays. If you must use

stationary images, reduce screen contrast and brightness to avoid screen damage.

yUnplug the TV before cleaning.

yClean the TV and frame with a soft, damp cloth. Never use substances such as alcohol, chemicals or household

cleaners on the TV.

yRisk of damage to the TV screen! Never touch, push, rub or strike the screen with any object.

yTo avoid deformations and color fading, wipe off water drops as soon as possible.
