3.
Observing the monitor screen at the same time, adjust

phase) while using the switch on the SEG to alternately
change between color bars of the internal RM-HP250 that
of the SEG.

then press the control knob to display “1A: SD H PHASE”
or “1B: HD H PHASE”.
6.
Press the control knob to move the cursor ( ) to the cur-
rently set value, then turn the control knob to adjust the H

● The following adjustments can be made more accurately when using a vectorscope and waveform monitor.
● Be sure to use an underscanned video monitor.
● It is not permitted to genlock the system components using a VCR playback signal.
● Before phase adjustment, wait a little for the phases of the connected components to stabilize.
NOTE
SC COARSE and SC FINE are linked.
When the upper or lower limit of SC FINE is exceeded,
the value of SC COARSE changes.
For example, when the value of SC COARSE is 0° and
SC FINE is increased, once SC FINE exceeds 127, SC
COARSE will become 90° and SC FINE will become -
128.
