Genlock adjustment
  Genlock adjustment
The genlock adjustment is performed to achieve phase
alignment by applying external synchronization (genlock)
when a multiple number of cameras will be used or when the
unit will be used in combination with other devices.
This unit supports BBS (Black Burst Sync) and tri-level sync
external synchronization signals.
Ask your dealer to perform this adjustment.
(Use a dual-trace oscilloscope for the adjustment.)
  Horizontal phase adjustment
Observe the waveforms of the external sync signal input
( tri-level sync signal) and video signal output on the
dual-trace oscilloscope, and use the wireless remote control
or controller to bring the horizontal phase into alignment.
