COLOR TEMP = HIGH
RED GAIN = 255
GREEN GAIN = 255
BLUE GAIN = 255
==========================
- WINDOW: The PFM-500A3W/510A2W has the built in window signal for white balance adjustment. There are two sizes that are the large and small windows. Select the optimum size window for white balance adjustment. OFF > Window does not appear. TYPE-1 > Small window. TYPE-2 > Large window. [When the white balance is going to be adjusted using an external signal perform the A/D converter calibration before starting the white balance adjustment.
- COLOR TEMP: To adjust the white balance, firstly select the desired color temperature from High, Low, 1,2,3,4,5 or 6 on the color temp sub-menu. Color temperature of items 1 to 6 are the same as those of the user menu.
- RED GAIN: Adjust the Red Gain of the selected color temperature. Range is from '010 to 255'
- GREEN GAIN: Adjust the Green Gain of the selected color temperature. The range of adjustment is from '010 to 255'
- BLUE GAIN: Adjust the Red Blue of the selected color temperature. The range of adjustment is from '010 to 255'.
ADC CALIBRATION MENU STRUCTURE.
Calibrate A/D converter IC 200 until non-uniformity between the R, G and B channels of the A/D converter is removed.
================================
ADC CALIBRATION
AUTO = OFF
CAL MODE = 128
RED GAIN = 128
GREEN GAIN = 128
BLUE GAIN = 128
RED BIAS = 128
GREEN BIAS = 128

================================
- AUTO: A/D converter is automatically calibrated. When sufficient adjustment accuracy cannot be obtained by the automatic calibration, perform basically the manual calibration using the following ADC CALIBRATION menu items.
- CAL MODE: A/D converter has the calibration mode as is operating mode as follows:
- A/D converter has R,G,B gain adjustments, and R,G,B bias adjustments. The Gain adjustment of the converter are used for 'Contrast' adjustment to the machine. The R,G,B Bias adjustments of the converter are used for the 'Brightness' adjustment of the machine. [CAL MODE OFF] > Standard display state. The R,G,B bias values are controlled by Contrast/Brightness data of the user menu. The R,G,B gain values and R,G,B bias values of the menu cannot be adjusted dependably
- CAL MODE OFF: Calibration mode > The R,G,B gain values and the R,G,B bias values of this menu can be adjusted independently. The R,G,B data that appears in the most bottom par of the menu in cyan, change from the indication "=====" to indication of any digital output data of the A/D converter.
- RED-GAIN | GREEN GAIN | BLUE GAIN > The respective R,G,B gain values can be adjusted independently. The range of the adjustment is form '000 to 255'.
- RED BIAS | GREEN BIAS | BLUE BIAS > The respective R,G,B bias can be adjusted independently. The range of adjustment is from '000 to 255'.
VIDEO PROCESSOR
The following items for the video processor can be adjusted using
this menu. However, all the items of the video processor have the
default values on which normal operations are performed. There fore the
video processor normally needs no adjustments.

----------------------------------------------------------------
AUDIO DIGITAL > Sets enable/disable of automatic switching of the 'digital In' terminal.
The PFM-500A3W/510A2W is equipped with the 'Digital In' terminal
using the LDVS. The automatic switching of the 'Digital In' can
be enabled/disabled as follows by the setup of the 'Auto Digital' item
of this menu.
- ON > When the 'Auto Digital' is set to ON, connect pin A20 to Gnd to switch the 'Digital In' terminal to the digital input. Disconnect pin A20 open to switch the 'Digital In' terminal to the input state before the terminal is switched to 'digital'.
- OFF > When the 'Auto Digital' is set to ON, the automatic switching of the 'Digital In' terminal is disabled. Set the 'Auto Digital' item to the 'ON' position normally.
DIGITAL TYPE > Selects either RGB signal or YUV signal as the input signal to the 'digital in' terminal.
- RGB: The RGB signal is selected as input signal to the 'Digital In' terminal.
- YOV: The YUV signal is selected as the input to the 'digital input' terminal.
- Set the digital type item to the 'RGB' position normally.
RGB 2 TYPE > Selects ether RGB signal or the YUV signal as the input signal to 'RGB 2' terminal.
- RGB: The RGB signal is selected as the input signal to RGB2 terminal.
- YUV : The YUV signal is selected as the input signal to RGB2 terminal.
- Set the RGB2 item to the RGB position normally.
AUTO PLL SETUP > Sets enable/disable of automatic execution of the 'Pixel Adjust' function. ON:
When 'ON' the 'Pixel Adjust' is automatically executed when the main
power is turned on or when input signal is switched. Be noted that
above 10 seconds are required to output the video signal after switching
the input signal when this function is kept "ON" position.
- OFF: The automatic pixel adjust is executed only when 'Auto' item of the user manu 'Pixel Adjust' is activated. This function becomes valied only when the signal that enables the 'Pixel Adjust' is inputted into the PFM500A3W/510A2W. [Set the 'Auto Pll Setup' to the 'OFF' position normally.
AUTO PLL PIXEL > Selects the functions that are automatically adjusted when 'Pixel adjust' is executed.
- ON: Both the 'Total H Pixel' and 'Dot Phase' are automatically adjusted.
- OFF: Only 'Dot Phase' is automatically adjusted.
- In the case PFM500A3W/510A2W used under the environment where the input signal contains much noise, there are cases that the 'Pixel Adjust' mis-operations. Therefore, set the 'Auto Pixel' to the 'OFF' position. In such case, the 'Total H Pixel' can be adjusted only manually. This function becomes valid only when the signal that leanness the 'Pixel Adjust' is inputted to the PFM-500A3W/510A2W. [Set the 'Auto Pixel' item to 'ON' position normally]
H/V SHIFT > Selects the method to control the horizontal and vertical picture shift.
- EDGE: When 'Edge' is selected, a picture is shifted by changing the starting position when reading data into memory. Using this function the entire area including blanking of all pictures can be displayed by shifting. The variable range of shifting is '1' horizontal and vertical period respectively.
- CAPT: When 'Capt' is selected, the picture that have already written into memory is shifted by a scan converter. Using this function a picture can be shifted as much as (+/- 50%) of a picture. When the picture is partially lacked at an end of a picture, the lacked portion of the picture cannot be displayed.
- Set the 'H/V Shift' item to 'EDGE' position normally.
VIDEO SHARP SW > Sets analogue
aperture On/OFF. The methods are used for the aperture correction of
the video signals [NTSC/PAL/SECAM/NTSC4.43/PAL-60 & YUV signals
having horizontal frequency of 15kHz]. These two methods are the
scaling filter and the analogue aperture of the scan converter.
- ON: Both the scaling filter and analogue aperture of the screen converter is used for aperture correction.
- OFF: Only scaling of the screen converter is used for aperture correction. [This function becomes valid only when the signal [NTSC/PAL/SECAM/NTSC4.43/PAL60 & YUV signals having horizontal frequency of 15KHz] is inputted to the PFM-500A3W/510A2W
- Set the 'Video Sharp SW' item to 'ON' position normally.
AUTO FT CHANNEL > Sets the Field
Tearing [FT] cancel circuit ON/OFF. The PFM-500A3W/510A2W has the FT
prevention circuit caused by over-run of memory while it is displaying
the moving picture. However there can be cases that noise appears on
the screen when FT prevention is being executed.
- ON: Th FT is cancelled in every picture size and every shift conditions as long as the TV is receiving the moving picture. When this item is set to "ON", noise may appear only once after the size/shift is adjusted. Noise does not last long but appears only once when the size/shift adjustment is complete.
- OFF: The FT cancel circuit is disabled. When 'OFF' is selected there can be a case that the field tearing appears on the screen depending on the adjustment conditions of the picture size/shift. However, noise due the operation of the processing circuit does not occur.
- Set the 'Auto FT Cancel' item to 'ON' position normally
