When using headphones, adjust the volume to appropriate levels, or hearing damage may result.

LCD SCREEN

Although the LCD screen is made with high-precision technology and has effective pixels of 99.99% or more, black dots or bright points or light (red, blue, or green) may appear constantly on the LCD screen. This is a structural property of the LCD panel and is not a malfunction.
The LCD screen is made with high-precision technology. To achieve a high level of performance and picture quality, this TV's backlight setting is set to maximize the brightness of the TV. However, uneven brightness may be observed when the LCD TV is viewed in a dark environment without an input source or a blank screen. This is a normal condition, not a malfunction of the TV. To improve this condition, change the Picture mode, Backlight setting, enable the Light Sensor, or turn on the Power management.
Avoid exposing the LCD screen surface to direct sunlight. It is likely to damage the LCD panel.
Do not push or scratch the LCD screen, or place objects on top of the TV. The image may be uneven or the LCD panel may be damaged.
If the TV is used in a cold place, a smear may occur in the picture or the picture may become dark. This does not indicate a failure. These phenomena improve as the temperature rises.
When still pictures are displayed continuously, ghosting may occur. It should disappear after a short period of time.
The screen and cabinet get warm when the TV is in use. This is a normal condition.
Spraying insect repellent with volatile material on the screen will cause damage.
Do not make prolonged contact with rubber or plastic material.

Broken pieces

Do not throw anything at the TV.
Doing so may break the screen glass and cause serious injury.

If the surface of the TV cracks, unplug the AC power cord before touching the TV.

Otherwise electric shock may result.

Handling of broken glass and liquid crystal leakage

If the LCD panel gets damaged, crystalline liquid leakage may occur, or scattered broken glass may result. Do not touch broken glass or crystalline liquid which is toxic, with bare hands as cuts, poisoning or skin irritation may occur. Also do not glass fragments or leaked crystalline liquid get into your eyes or mouth. Should either contacted your eyes or mouth, rinse the contacted area thoroughly with water and consult your doctor.

Mounting ViewSonic LCD TV to the wall

The LCD TV can be used in a free standing position or wall-mounted. Before installing the product to the wall, please consider the following guidelines:

• Due to safety concerns, if the VESA mounting kit is purchased separately please make sure the mounting kit is UL-Listed, and replaceable only by service personnel.
• Read the Important Safety Instructions, at the start of this manual.
• Do not install in a moist or wet environment. This equipment is intended for indoor use.
• Do not install near heat source, or strong magnetic fields.
• Use only ViewSonic approved wall-mounting brackets to support the LCD TV weight.
• Before attaching the wall mount plate to the back cover, ensure the product is working.
• If your LCD TV is already set up for free-standing operation, you need to first remove the stand before mounting the device to the wall.

To attach the wall-mount bracket to LCD TV safely, please use the following guidelines:

• Disconnect the power and any other cables that might hinder moving the LCD TV.
• Set the LCD TV on a table or work surface, placing the screen face down on a towel or woolen blanket to protect the screen surface from damage while installing plate.
• Before installing the LCD TV on the wall, ensure you have recorded the product serial number on page (i) of the User Guide, as you will need the serial number to request service should there be a service need.
• Install the wall mount plate to the LCD TV using screws NO LONGER than 10mm , as longer screws found in universal (non-ViewSonic) wall mount kits may damage the power supply causing the unit to fail. The wall-mount screw type is M4 x L10.

• Mount the wall mount bracket to the wall ensuring use of proper screws to support the installation. Ensure there is at least 3cm of space surrounding any air-vents of your LCD TV to allow adequate cooling during operation.
• Hang the LCD TV wall mount plate to the wall mount bracket, completing installation. Enjoy your ViewSonic LCD TV!
