③ FORCED COL/MONO switch
(Functions only when the NTSC decoder is mounted)
The function of this switch differs as follows
according to the state of the MONO switch on the
front panel. This switch functions only when analog/
digital (4Fsc : D2/3) composite signals are input.
FORCED MONO
COL/MONO SWITCH
SWITCH
<AUTO COLOR>
OFF OFF Switches the COLOR/MONO circuit operation
of the decoder automatically according to
whether burst is added to the composite signal.
<FORCED COLOR>
OFF The COLOR circuit is operated forcibly
ON
regardless of whether burst is added to the
composite signal.
<NORMAL MONO>
OFF ON Normal MONO state. In the case of the
composite signal, either the COMB or TRAP
filter circuit operates according to the state
of the COMB switch for composite signals.
<WIDE BAND MONO>
ON Neither the COMB nor TRAP filter circuit
ON
operates in the MONO state. Frequency
characteristics of the luminance signal are
in the full-flat state.
④ EXT SYNC switch
Set this switch to EXT when externally
synchronizing the analog input signal. The switch
does not function when digital signals are input.
⑤ RE.SC switch
(only when equipped with DE-811 module)
Use the RESIDUAL SUBICULAR ON/OFF switch
to check if the subicular is leaking to the signal
input.
Press this switch while observing the screen. If
the phase (HUE) changes, it means that the
subicular is leaking into the feedback line area.
Releasing the switch automatically sets it to OFF.
⑥ CHANGE PRESET switch
Press this switch to change or memorize the
PRESET data.
When pressed, all the PRESET LEDs in the frame
start to blink. Select a blinking PRESET switch.
When the LED stops blinking and stays lit on, the
data can be changed using the rotary encoder.
Press another PRESET switch to change another
data.
Each PRESET data has the following individual
data.

* While changing the PRESET data, do not switch
the ASPECT, SCAN and the channels.
* Activate the following PRESET switches by
enabling their functions.
a) APT PRESET switch
Set the APT switch on the front panel to ON.
b) HUE PRESET switch
When the HUE MANUAL switch on the front panel
is ON, set it to PRESET. The switch is enabled
only when the NTSC composite signal is selected.
c) CHROMA PRESET switch
When the CHROMA MANUAL switch on the front
panel is ON, set it to PRESET.
d) BRIGHTNESS PRESET switch
When the BRIGHT MANUAL switch on the front
panel is ON, set it to PRESET.
e) CONTRAST PRESET switch
When the CONT MANUAL switch on the front
panel is ON, set it to PRESET.
⑦ CLEAR switch
Press this switch to select the item you want to
change or clear the data in the PRESET screen
displayed by operating the CHANGE PRESET
switch and WHITE BALANCE switch.
While changing any preset data, press this switch
to clear the new data and restore the previous one.
