The cursor starts blinking. 12. Press € or B to match the color (hue) of the camera’s video signal, when observed at the output of the Special Effect Generator (SEG) or -2 Switcher, as closely as possible to the color of the original scene. The SC FINE adjustment has a range of 90 degrees of color shift. Notes: • When the “I” cursor reaches the “+" end, it jumps back to . At the same time, SC COARSE is incremented by one step to enable a continuous adjustment. The reverse takes place when the "I" cursor reaches the end. • When or is kept pressed for a second or more, the “I" cursor moves quickly. • For more accurate adjustment, supply both the original camera video output signal and the effect output video signal (program output video signal) of the special effects generator (SEG) to a vectorscope and compare the chroma phase of both signals. • To reset SC COARSE and SC FINE to the values preset at the factory, press or simultaneously. SC COARSE is reset to the factory setting. 8- 6-2. VS Gen-lock Mode (EXT(VS)) 1. Move the cursor to the SYNC parameter and select INT. 2. Connect the coaxial cable for the composite sync or composite B/W video signal to the gen-lock input connector. 3. Confirm that the parameter INT changed to EXT (VS) on the menu. Caution: The gen-lock input signal should meet with EIA RS-170 specifications and should not contain jitter, such as a VCR playback signal , as it could disturb synchronization. f- —s ** CAM SET UP •• ** CAM SET UP »* CAMERA ZD OFF n CAMERA ID OFF n ALC/ELC ALC “1 ALC/ELC ALC ~l SHUTTER OFF SHUTTER OFF AGC ON AGC ON SENS UP OFF 4 SENS UP OFF SYNC INT SYNC EXT (VS) WHITE BAX.

Supply the video output signal of the camera to be adjusted and the reference gen-lock input signal to a dual-trace oscilloscope. 7. Set the oscilloscope to the horizontal rate and expand the horizontal sync portion on the oscilloscope. 8. Adjust the horizontal phase by pressing O or . The adjustable range is 0 - 2.0ps. 6-3. Line-lock Sync Mode (LL) Note: The line-lock (LL) sync mode is not available when the camera operates on DC power. 1. Move the cursor to the SYNC parameter and select LL. Note: The settings in this menu can be made only when the multiplexed vertical drive signal (VD2) is not supplied to the camera. -29- 2. After confirming the cursor is on LL, press C3.

Move the cursor to FINE. The cursor starts blinking. 8. Press -Q or to match the vertical phase for both video output signals as closely as possible. (FINE adjustment can be made up to 22.5 degrees by pressing €1 or ©.) Notes: * When the “I" cursor reaches the “+" end, it jumps back to At the same time, COARSE is incremented by one step to enable a continuous adjustment. The reverse takes place when the T cursor reaches the end. • When or & is kept pressed for a second or longer, the “I" cursor moves faster. 1(1-- 2(1-- 16(1 -_I 0- • To reset COARSE and FINE to the values preset at the factory, press C] or simultaneously. COARSE and FINE adjustments are preset at the factory to zero-crossing of the AC line phase. • If the AC line contains noise (spike noise, etc.), the stability of the vertical phase of the camera video output signal may be disturbed. 7. White Balance Setting (WHITE BAL) 7-1. Auto-Tracing White Balance Mode (ATW) You can select one of two modes for white balance adjustment as follows: • ATW (Auto Tracing White Balance) In this mode, the color temperature is monitored continuously and thereby white balance is set automatically. The color temperature range for the proper white balance is approximately 2 600 - 6 000K. Proper white balance may not be obtained under the following conditions: 1. The color temperature is out of the 2 600 -6 000K range. 2. When the scene contains mostly high color temperature objects, such as a blue sky or sunset...
