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.

<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.

Image controls

These controls are used to adjust the peaking/color 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 color 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 color 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.
