④ EXT SYNC switch
Set this switch to EXT when externally synchro-
nizing the analog input signal. The switch does
not function when digital signals are input.
⑤ RE.SC switch
(Functions only when the NTSC decoder is
mounted)
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 sub-
icular is leaking into the feedback line area.
Releasing the switch automatically sets it to OFF.

Press this switch to change or memorize the PRE-
SET 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.
