activates to make more accurate Y /C separation. This
contributes to less of a decrease in resolution, cross
color and cross luminance phenomena.
Beam current feedback circuit
The built-in beam current feedback circuit assures
stable white balance.
Four color system available
The monitor can display NTSC, PAL, SECAM and
NTSCw
21
signals. The appropriate color system is

RGB scanning lines may appear on the top edge of lhe
screen. These are caused by an internal test signal,
: rather than the input signal.
Horizontal/vertical delay mode
The horizontal and venical sync signals can be
checked simultaneously in the HIV delay mode.
Auto/manual degaussing
Degaussing of the screen can be performed
automatically when the power is turned on, or
manually by pressing the DEGAUSS button.

SDI (Serial Digital Interface) Kit
By using the following optional SDI Kits, the monitor
can display SMPTE 259M 4:2:2 serial digiral signal
from a digital VCR. (ex. Sony 4:2:2 VCR)
- BKM-IOlC: Component SDI Kit (for video)
- BKM-102: Component SDI Kit (for audio)
...
When the serial number of the BKM-IOlC you want to
connect is less than 2,010,000, an optional connecting
harness (pan no. 1-900-230-35) will be required.
Serial Remote Interface Kit
By using the oplional BKM-103 Serial Remote
Interface Kit, the monitor can be controlled from
