[3 OF 3]
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.

==========================
  • 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'.
