LCD (LIQUID CRYSTAL DISPLAY) MONITOR
The operation of the LCD monitor is a very simplc operation. There are two brightness buttons on the unit for increasing brightness (+) and decreasing brightness (-). These buttons MIl adjust brightness for the type ofvideo source being used, and also adjust for the vicMng angle. See Figure I. The color and the tint of the monitor are factory preset, but if the monitor is ever in need of adjustment there are
color and tint controls on rear of monitor. See Figure 2.
PRECAUnONS:
*Use the unit in the temperature ranges of O C to 60 C (32 F to 140 F). *Do not push on the LCD display, forcibly pushing on the display may damage the picture quality of the
unit.
*When using unit in cold surroundings, delayed or double images may appear. This is not a defect of the
unit. When the monitor warms up, the video will become normal again.
*Clean unit with a soft cloth slightly dampened with a mild detergent. A strong solvent used to clean the
monitor can damage the finish of the unit.
*Due to the extreme manufacturing tolerances required, even in a high quality screen, it is IX>ssible that
the display might evidence a few dots {black or colored) on the screen. These dots are considered normal.

SIGNAL DISTRIBunON BOX
The distribution OOx is the heart of the FlexVision system. This OOx distributes all of the \ideo and audio signals to the proper monitor. This gives each person using the S)'stem the flexibility to choose ~.hat they want to do regardless of \\'hat an)-body else in the vehicle is doing. For example: one person could
be watching television, another person playing a vicko game, another watching a video tape, and yet
another listening to the radio. Each distribution box can drive up to four monitors (optional) and selector stations. Figure 6 shows a basic setup diagram emphasizing the Signal Distribution Box.
