V-Phase Adjustment Push Button
This camera is designed to keep the initial data value of V-phase in EEPROM.
NOTE : This camera offers V-phase adjustment over a range of ±180°. If two or more
cameras are connected to a switcher and the picture on the monitor rolls while
switching from camera A to B, adjusting the vertical phase (V-phase) of the cameras
will probably eliminate the rolling. If this adjustment is necessary, it should only be
performed by a qualified technician. Before making any adjustment, confirm that
cameras A and B are connected to the power supply with the same polarity.
To make an adjustment, follow the steps below.
1. While observing the video output signals from both cameras on an oscilloscope,
press camera A's V-phase control pushbutton (on back of camera) until vertical sync
from both cameras are in phase.
2. If camera A's adjustment range is insufficient, adjust camera B's V-phase control
pushbutton in the opposite direction to camera A until they are in phase.
3. If these adjustments do not bring vertical sync from both cameras in phase, recheck
the polarity of the power supply connections.
