Precautions for use
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 lighted (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.
Do not expose the liquid crystal display to strong light, as it could cause a deterioration in the display characteristics and reduce the display quality.
Do not keep in an environment where the temperature changes suddenly, because condensation could form on the surface of the liquid crystal or in the internal parts and cause a reduction in the display quality or a malfunction.
Screen irregularities may be generated when certain images are displayed.
If the unit is left for a long time in a location with a high temperature or humidity, it could change the characteristics of the liquid crystal panel and cause irregularities.

Outline
The BT-LH80W is a thin and lightweight liquid crystal monitor designed especially for broadcasting service and business use. It is equipped with a 7.9-inch V (effective display area) liquid crystal display panel.
It can be used as a VF (viewfinder) for broadcasting and business cameras made by Panasonic.
Equipped with a new IP conversion circuit, the circuit processing greatly reduces time delays
A new I/P conversion circuit has been introduced that converts and generates SD and HD interlace signals to high-precision progressive signals without generating time delays per field.
Equipped with a diagonal line correction processing circuit
By detecting correlations in the field in the diagonal direction in addition to the vertical direction, the unit performs the optimum interpolation to minimize the rough noise occurring in the diagonal direction and create a smooth image.
New functions that support focus adjustments
•FOCUS-IN-RED function
The section of the image that is being focused is displayed in an easy-to-understand red, making camera focus adjustments very easy.
•PIXEL TO PIXEL function
The input signal is displayed without being resized, greatly facilitating camera focus adjustments.
If you are not resizing the image, you can check the image by expanding a 1080/60i signal to the equivalent of an image approximately 19 inches wide.
Thin, lightweight, compact and low energy consumption
The unit has a compact body that makes the most of the thin and lightweight characteristics of LCD panels, with a depth of 64.7 mm (2-9/16 inches) and a weight of 1.5 kg (3.3 lb).
Further, it is compatible with HD and has low energy consumption.

<Notes>
•Use a shield cable with a length of 2 m (6.56 feet) or less for the DC cable. Use of cords any longer than 2 m (6.56 feet) may result in noise appearing on the screen.
•If the battery pack and an external DC power supply are connected simultaneously, then the external DC power supply will have priority.
If the external DC power supply is used, then the battery pack may be fitted or removed.
•If an external DC power supply is used, then make sure that the external DC power supply is first turned ON, then this unit is turned ON. If they are turned ON in the reverse order, then this unit may malfunction, because the output voltage of the external DC power supply will gradually increase.
•Input voltage that above the specification is not displayed accurately.
