Contents

This product has been specially designed for commercial use. As such, it should be used and operated only by persons with related expertise.

¥ The liquid crystal parts are fabricated using high-precision technology. The screen has effective pixels that cover

more than 99.99% of its area, but pixels may be missing or remain permanently lit (red, blue and/or green) in less than 0.01% of the area. This is not indicative of malfunctioning.

¥ The panel which protects the liquid crystal display has been specially treated.

Do not wipe it with hard cloths or rub it heavily as this will damage the surface of the panel.

¥ If a still image is displayed continuously for a long period of time, the image may be burnt onto the screen for

some time. (The shadow of the image will usually disappear after moving images are displayed for while.)

¥ The response speed and brightness of the liquid crystals will vary with the surrounding temperature.

Introduction

Designed for use in broadcasting and commercial applications, the model BT-LH900E is a slim-line and lightweight liquid crystal video monitor with an 8.4-type liquid crystal screen. For use, secure it in place by, for instance, installing it in a rack by using the optional rack-mounting adapters BT-MA900G or mounting it on a tripod. (For details, refer to the instructions in the operation guide of the BT-MA900G.)

∫ Slim design, light weight, compact size, low

power consumption and driven by DC power

Since this monitor uses an LCD panel, it has a slim design, light weight and compact size. Furthermore, while supporting HD specifications, it has a low power consumption, and it can be operated using DC power: these are all features which make the monitor useful in outdoor locations.

∫ Multiple formats supported

In addition to its two lines of SDI input connectors (automatic HD/SD switching), the monitor provides one line each of component input connectors and composite input connectors.

∫ Wide viewing angle

The monitor can display excellent images over an angle extending for 170 degrees in both the top-bottom and leftright directions.

∫ High-definition images

At 1024 a 768 dots (XGA), the large number of screen pixels ensures a high colour reproducibility and tonal range.

∫ Functions

The main controls can be relocated to the bottom surface or right panel of the main unit to support monitor specifications, viewfinder specifications and other applications.

≥ The monitor comes with a film gamma correction

function to support its use as the viewfinder for the AJHDC27F. (For further details, consult with your dealer or a Panasonic Service Centre.)

≥ Waveform monitor functions provided ≥ Marker functions and blue-only function incorporated ≥ RS-232C external control, remote control using GPI

connector enabled

Tally lamps

In the above illustration, the R (red) tally lamp is shown on the left and the G (green) lamp appears on the right. These tally lamps can be lit by initiating the GPI ON/OFF operation.

<Note>

When the monitor is used outdoors, it may be hard to see that the tally lamps are in fact lit.

Power LED

This is the power LED. It lights while the power is ON.

Function buttons

INPUT button

This button is used to select the signal input. Each time it is pressed, the input channels are switched by one setting in the following sequence: SDI 1 > SDI 2 > VIDEO > YPBPR/RGB. By means of the INPUT menu settings, the unused channels can be skipped.

MENU/EXIT button

This button is used to display the menus. When it is pressed while a menu is already displayed, the menu display is cleared or the menu at one hierarchical level above is restored. When the button is pressed while a setting is being changed, the setting established prior to the change is restored, and the menu at one hierarchical level above is restored.

HD ZOOM/XXbutton

This button is used to move the cursor or change settings while a menu is displayed. If there is no menu display, it turns the HD ZOOM function ON or OFF. When the button is pressed, both the left and right sides of the images with a 16:9 aspect ratio produced by HD signals are cut off, and images with a 4:3 aspect ratio are displayed on the entire screen. When it is pressed, the original images are restored. The HD zoom function does not work when images of SD signals are displayed.

FUNCTION

2 3 4 5

Controls 2, 3 and 4 can be separated from the monitor main unit as the main controls and relocated to the bottom surface or right panel of the main unit.

Image controls

These controls are used to adjust the peaking/colour phase, chroma, brightness and contrast. When a control is pushed in, it pops out to enable adjustment. When a numerical value is changed from the default setting, the lamp to the left of the control lights. The adjustments performed using these controls are valid only when the controls are in the “out” position, and when a control is pushed back in, the value adjusted by that control is returned to its default setting.

PEAK/PHASE (PEAKING/PHASE)

This control is used to adjust the peaking or phase. Which of these is to be adjusted is set using the PEAKING/PHASE item on the SYSTEM CONFIG screen.

≥ PEAKING This function is selected when the monitor is to be used as a viewfinder. It is used to set the edge sharpness. Any value from 0 to 30 can be set: the higher the value, the sharper the edges. The default setting is 0. ≥ PHASE This function is selected when the monitor is to be used as a monitor. It is used to set the colour phase of the screen. Any value from 0 to 60 can be set. The default setting is 30.

<Notes>

≥ When the blue-only function is ON, the control

functions as the PHASE control regardless of the setting.

≥ The colour phase cannot be adjusted when

RGB signals are input.

CHROMA

This control is used to adjust the image chroma. Any value from 0 to 60 can be set. The default setting is

30.

<Note>

The chroma cannot be adjusted when RGB signals are input or when the MONO setting is ON.

BRIGHT

This control is used to adjust the image brightness. Any value from 0 to 60 can be set. The default setting is 30. However, the brightness cannot be adjusted when blanking is displayed using the HV DELAY function.

CONTRAST

This control is used to adjust the image contrast. Any value from 0 to 60 can be set. The default setting is

50.

FUNCTION/ENTER button

This button is used to enter changes or settings while a menu is displayed. If there is no menu display, the button’s function changes depending on which FUNCTION item on the menu is selected. One of the following three items can be selected. (Refer to page 19)

UNDEF: No function is allocated to this item. HV DELAY

: Image blanking is displayed. Each time

the button is pressed, the blanking display is switched by one setting in the following sequence: H blanking display > V blanking display > H and V blanking display > no blanking display.

WFM ON/OFF

: The Y signal (luminance) waveform is

displayed at the bottom right of the image. When the button is pressed again, the display is cleared. When waveforms are displayed in the 16:9 mode, the image displayed on the screen moves to the upper part of the screen so that it will not be superimposed onto the waveform display.

<Notes>

≥ In order for this function to be used, it is necessary to

select WFM as the FUNCTION item setting on the SYSTEM CONFIG screen, and then select FUNCTION as the WFM item setting.

≥ The WFM function is a simplified one and, as such, finely

detailed waveforms may not be displayed accurately. In addition, differences in the input signal format or input function may result in the display having a different horizontal width.

The image remains unchanged in the 4:3 mode.
