Regarding Genlock Signal and
Adjustment of System Phase
When using the RM-P210 Remote Control Unit with this sys-
tem, input Genlock signal into either the GY-HD250 Camera
or RM-P210.
However, if Genlock signal is applied to both GY-HD250 and
RM-P210, screen images will appear choppy.
Perform System Phase adjustment on the machine where
Genlock signal has been input.
In addition, RM-LP55 is prioritized when connected.
• When Genlock signal is input into RM-P210
Adjust the phase by adjusting RM-P210's H and SC.
• When Genlock signal is input into GY-HD250
Adust the phase by adjusting RM-P210's H and GY-
HD250's SC.
