@ !SAFE TITLE) Switch
When this switch is pressed, a frame from 80% to
100% in intervals of 5% can be outp ut and at the
same time three frames of 80%, 90%, and 100% can be
output on the screen. 5-partition cross hatch and 10-
partition cross hatch can also be output.

· The 80% frame expresses the safe title area of the
SMPTE recommendat ions and the 90% frame displays
the safe action area.
· Since the 95% frame is the
same size as for over scan,
you
can set the over scan size if you adjust the screen
size so that the escutcheon frame and the 95% frame
match.
· The 100% frame
can be used for H. phase adjustment .
For details on the adjustment method, see 5-4.(8).
You can also visually check the video blanking width
and check the input signal video phases.
· 5-partition cross hatch
and 10-partition cross hatch
can be used to set the position of the camera location.
@!COM Bl Switch
For composite video input, when the NTSC decoder
board is selected(NTSC mode), pressing this switch
lights up the LED and uses
a CCD comb filter circuit
for luminance signal and chroma signal separation.
When the LED
is off, a trap circuit is used.
The CCD comb filter circuit eliminates the drop in
resolution when the color signals are reproduced.
When the optional Faroudja comb decoder board
(DE305) is used, this comb circuit
is always used and
separatio n does not switch to the trap circuit .
@!S-PALI Switch
For composite video input , when the P AL-B decoder
boa.rd is selected(function does not work when the
P AL/SECAM decoder board or P AL-M decoder board
is selected), pressing this switch lights up the LED
and makes the demodulation simple PAL. When th e
LED
is off, the demodulation is delay PAL.

j does not use a. delay line. It simply converts the
. modulation output to light
as is. In other words, it
I uses the average effect of the human eye and
· alternates every other scanning line between
+ and
I -to eliminate the color phase error . . _ . _ . _ .
@!SCREENS! Switch
These switches switch the R/G/B screens on/off.
There are two modes for the!SCREENSlswitches . For
details on the setting method , see 5-6.(6). When all
the screens are "ON", the LEDs are all "OFF".
Caution
When the SCREENS LEDs blink, this warns that
the memory
backup battery is runn ing low.
Replace it with a new
3V lithium battery. For
deta ils on how to do t his, refer to the service
manual.
