TEST switch
Turn ON to switch to the internal TEST signal.
The following standard TEST signal formats are
provided.
Switch the format at the MENU 1-5 item.
480i(525i)/59.94
575i(625i)/50
480p/59.94(Only when supported by the monitor)
1035i/60
1080i/60
1080i/50
1080p/24sF (1080i/48) (Only when supported by the
monitor)
720p/60
720p/50 (Only when supported by the monitor)
* The description in parentheses appears on the
MENU.
As the ASPECT 4:3/16:9 setting is memorized
irrespective of the format, it is switched
automatically when the new setting is done.
Every time the switch is pressed, the output will
cycle over the following five types of signals.
Normal Screen

⑥ EXT SYNC LED
The LED lights up when SYNC INT/EXT is
switched to EXT.
⑧ APT switch
Turn ON the APT switch when correcting aperture.
⑨ ASPECT switch
Aspect ratio is switched between 4:3 and 16:9.
In the HDTV signal mode for 16:9 image, the 4:3
area image is displayed with enlargement.
When [CHANGE ASPE] is set to [ AUTO ] in MENU
2-4, the aspect settings are memorized in the
following seven input channels and there is no need
to repeat the setting every time the input channel
or signal format is changed. The setting is switched
automatically together with the channel switching.
In the case of the Multi-format SDI input, the
aspect ratio data is memorized in each input signal
(HD-SDI or SD-SDI) respectively. When HD-SDI
(16:9) signal input at the channel A is replaced by
SD-SDI signal, for example, the aspect ratio is
automatically switched to the one previously set
for that SD-SDI signal. To fix the aspect ratio
setting, set [CHANGE ASPE] to [ MANUAL ].
<Channels for Memory>
VBS input ch A / B / C
2nd VBS input ch A / B / C
YPbPr/RGB inputs ch/A/B
Multi SDI inputs ch/A/B
(memorized in SD/HD-SDI respectively)
2nd SDI inputs ch/A/B
Ex: By setting the channel A to 4:3 and the channel
B to 16:9 once, the ASPECT will be switched
automatically each time the channel A/B is
switched.

⑦
MONO (SPLIT) switch
Set the MONO switch to ON when the color signal
is to be viewed in the black/white state.
When the MONO switch is ON with the NTSC
composite signal ( DE-811 module) selected, the
luminance (Y) signal is usually filtered with a comb
or trap filter. If the FORCED switch in the drawer
panel is turned on, the wide-band MONO mode
with unfiltered flat frequency characteristic is
called up.
COLOR/MONO SPLIT
When the MONO switch is pressed for 2 to 3
seconds, the split screen (upper half of the screen
is color, while the lower half is black/white) mode
will be set. Press this switch again, and the color
mode is resumed.
