INSTALLATION

Optional wall mount

To do Wall mount installation, you need a Wall-Mount Bracket. When installing or removing the TV using the Wall-Mount Bracket, be sure to use qualified contractors. If not properly secured during installation or removal from the Wall-Mount Bracket, the TV may fall and cause serious injury.

When installing the TV using a Wall-Mount Bracket, make sure you follow the operating instructions supplied with the Wall-Mount Bracket.

• Attach the brackets supplied with the Wall-Mount Bracket.
• The TV is not designed for hanging from the ceiling. It may fall and cause serious injury.

Placement

The TV should be installed near an easily accessible AC power outlet.

Observe the following to prevent the TV from falling from the stand or wall mount.

• Place the TV on a stable, level surface.
• Do not hang anything on the TV. Do not allow

children to climb on the TV.

Do not install the TV in places subject to extreme • temperature, such as in direct sunlight, near a radiator, or heating vent. If the TV is exposed to extreme temperature, the TV may overheat and cause deformation of the enclosure or cause malfunction.

Do not install the TV in a place exposed to direct air conditioning.

If the TV is installed in such a location, moisture • may condense inside and may cause a malfunction.

Do not place the TV in hot, oily, humid or • excessively dusty places.

Do not install the TV where insects may enter.

Do not install the TV where it may be exposed to mechanical • vibration.

Do not install the TV in a location where it may spear up, such as on or behind a pillar, or where you might bump your head on it. It may cause injury.

Preventing the TV from toppling over

To prevent the TV from toppling over, secure the TV to a wall or stand.

Placement for watching

We suggest you to watch the TV at a distance of 3-7 times that of the screen height, and not in excessive brightness. It is easy to cause eye fatigue if you watch TV for too long or in a dark room. To obtain clear picture, do not expose the screen to direct illumination or sunlight. Use spot lighting directed down from the ceiling if you can.

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 LED 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. It is not caused by a failure. This condition will 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.

SERVICING

Do not attempt to repair the TV yourself, since opening the cabinet may expose you to dangerous voltage or other hazards. Ask qualified service personnel to do the servicing for your TV.

Replacement parts

When replacement parts are required, be sure the service technician certifies in writing that he/she has used replacement parts specified by the manufacturer that have the same characteristics as the original parts. Unauthorized substitutions may cause a fire, an electric shock or other hazards.

Safety check

Upon completion of repairs to the TV, ask the service technician to perform routine safety checks (as specified by the manufacturer) to determine that the TV is safe for operating, and to so certify.

Ask a qualified service technician to dispose of the TV.

    A["Cable"] --> B["A-B RF switch"]
    C["Antenna"] --> B
    B --> D["Rear of TV"]
    D --> E["VHF/UHF/CABLE input"]

RS232 Protocol

1. Introduction

This document describes the hardware interface spec and software protocols of RS232 interface communication between Viewsonic Commercial Display and PC or other control unit with RS232 protocol.

The protocol divide into three sections:

• Set-Function
• Get-Function
• Remote control pass-through mode

※In below document, “PC” will represent all the control units that can sent or receive the RS232 protocol command.

2. Description

6. Remote Control Pass-through mode

When PC sets the LCD monitor to Remote Control Pass through mode, the LCD shall send a three bytes packet (followed by “CR”) in response to RCU button activation. Note, that in this mode the RCU shall have no effect on the monitor function. For example: “+Volume” will not change the volume in the LCD but only sends “+Volume” code to PC over the RS232 port.

RCU Pass-through Command description:
