Precautions with regard to safety

WARNING

Setting up

Set up the monitor in a place which is strong enough to support it.

• If the setting-up location is not strong enough, the monitor may fall down or tip over, and damage or injury may result.

Do not place anything on top of the monitor.

• If liquid gets spilled on the monitor or foreign objects get inside it, short-circuits can occur which may result in

fire.

If any foreign objects get inside the monitor, contact an Authorized Service Center.

Do not place the monitor on top of surfaces which are unstable.

• If the monitor is placed on top of a surface which is sloped or unstable, it may fall down or tip over, and injury or

damage could result.

Using the monitor

Do not remove the rear cover or cabinet or make any modifications yourself.

• High voltages which could cause fire or electric shocks are present inside this monitor.

Consult the place of purchase for any inspection, adjustment and servicing needs.

Do not insert any foreign objects into the monitor.

• Do not insert any metal objects or flammable objects into the monitor or drop them onto the monitor, as doing so

can result in fire or electric shocks.

Clean the power cable regularly to prevent it from becoming covered in dust.

• If dust builds up on the power cable plug, the resulting humidity can damage the insulation, which could result in

fire. Pull the power cable out from the wall outlet and wipe it with a dry cloth.

• If not using the monitor for an extended period of time, pull the power cable plug out from the wall outlet.

Do not damage the power cable or power cable plug.

• Do not damage, modify or bind the cable, place heavy objects on top of the cable, heat the cable or bring it

close to hot objects, twist or pull the cable strongly. If the cable is not handled properly, the live wires may

become exposed or a short-circuit may develop, and fire or electric shocks may result.

• If the power cable becomes damaged, contact an Authorized Service Center for repairs.

Do not pour liquid on the monitor or otherwise allow it to become wet.

• Fire and electric shocks may result.

Insert the power cable plug securely into the wall outlet.

• If the plug is not inserted correctly, overheating, fire or electric shocks could result.

If problems occur during use

If a problem occurs (such as no image or no sound) or if you notice smoke or a strange smell coming from the monitor, immediately turn off the power and disconnect the power cable from the wall outlet.

• A short-circuit could develop, and fire or electric shocks may result. Contact an Authorized Service Center for repairs.

• Check that no more smoke is coming out, and then contact an Authorized Service Center for repairs

• Do not attempt to repair the monitor yourself, as this can be dangerous.

If foreign objects or liquids get inside the monitor, or if the monitor is dropped or the cover is broken, turn off the power and disconnect the power cable from the wall outlet.

CAUTION

Setting-up

Do not set up the monitor in humid or dusty places or in places where the monitor may come into contact with smoke or steam.

• To do so may result in fire or electric shocks.

Do not use a power supply which is outside the specified voltage range (120 V AC).

• To do so may result in fire or electric shocks.

Do not cover the ventilation holes.

• If the ventilation holes are covered, the inside of the monitor could overheat, and fire may result. Leave a space of 10 cm or more between the monitor and the wall and maintain a distance of 10 cm or more between the monitor and any audio/visual equipment when setting up the monitor.

• Do not place the monitor facing straight up or straight down, and do not tilt it on its side or place it upside down or place it somewhere where there is poor ventilation.

• Do not place a tablecloth over the monitor, or place it on top of a rug or quilt.

When using the monitor

Do not place any heavy objects on top of the monitor.

• Doing so can cause the monitor to become unbalanced and fall, which could result in damage or injury.

Take steps to prevent the monitor from moving or turning after setting-up.

• If the monitor moves or tips over, injury may result.

• If placing the monitor on top of a table with casters, make sure that the casters are prevented from moving.

Do not sit on top of the monitor.

• Doing so may cause the monitor to tip over or break, and injury may result.

Always disconnect the power cable before moving the monitor.

• Moving the monitor with cables still attached can damage the cables, and fire or electric shocks may result.

• Always check that the power cable plug and cables are disconnected before moving the monitor.

• Two people are needed for unpacking and moving the monitor.

When disconnecting the power cable, hold the plug, not the cable.

• If the power cable itself is pulled, the cable will become damaged, and fire, short-circuits or serious electric shocks may result.

Do not handle the power cable plug with wet hands.

• Doing so may result in electric shocks.

Observe the following when handling the batteries.

• Make sure the polarities 0 and 0 are correct.

• Use only the batteries specified.

• Do not heat or disassemble the batteries or place them into water or fire.

• Remove the batteries if not using the remote control unit for long periods.

• Do not place the batteries in a container together with metallic objects such as necklaces.

• If batteries are not treated properly, they may leak, and fire, electric shocks or contamination may result.

• If the batteries start leaking, contact an Authorized Service Center.

• If battery fluid gets onto your body, wash well with copious amounts of running water.

Cleaning

Ask an Authorized Service Center to clean inside the monitor at least once a year.

• If dust is left to build up inside the monitor without being cleaned out, fire may result. It is a good idea to clean the inside of the monitor before the season for humid weather arrives. Please discuss with the Authorized Service Center regarding cleaning costs.

Disconnect the power plug from the wall outlet as a safety precaution before carrying out any cleaning.

• Electric shocks may result if this is not done.
