© V phase adjustment
if the camera is to be used in the line-lock sync mode, the
vertical phase may require adjustment to synchronize the
vertical phase of the camera with other camera in the sys-
tem. (Vertical phase is adjustabie over the range of +90°.}
Make this adjustment when the vertical phase of the
camera does not match with other cameras (or systems).
For correct adjustment, use a multichannel oscilloscope.
This vertical phase adjustment can only be made when the
camera is operating in the line-lock sync mode
Notes:
@ When AC power line frequency is of 60 Hz, the line-lock
sync operation is not possible.
When adjusting the V phase control to observe the AC
24 V waveform, connect the positive pin of a probe to
either of the power input connector.
This adjustment is necessary only when the line-lock
sync operation is performed.
For more details, consult your loca! dealer.

@H phase adjustment
For adjusting the horizontal phase when gen-lock (ar H/V
lock) operation is performed. Adjust with reference to other
camera(s) in the system.
Notes:
e Gen-lock (or H/V lock) operation may become unstable
using a signal containing severe jitter (vertical or hori-
zontal picture vibrations) such as a video recorder play-
back signal.
e This adjustment is not necessary unless gen-lock (or
H/V lock) operations are performed.
@ For more details, consult your local dealer.
@ SC phase fine adjustment control
@ SC phase coarse adjustment switch
For adjusting the colour sub-carrier phase when gen-lock
operation is performed. Adjust by changing the setting of
the SC phase coarse adjustment switch (A/B) in conjunc-
tion with the SC phase fine adjustment contro! with refer-
ence to other camera(s) in the system.
Notes:
e Gen-lock operation may become unstable using a sig-
nal containing severe jitter (vertical or horizontal picture
vibrations) such as a video recorder playback signal.
e This adjustment is not necessary unless gen-lock oper-
ations are performed.
e For further details, consult your local dealer.
