Connect a coaxial cable (procured locally) to
the video output connector.
Important:
• When connecting a coaxial cable to the video output connector, make sure that the
coaxial cable connector is locked firmly.
Connect the video output connector to the monitor or other system device with a coaxial
cable. The maximum extendable length is shown in the table.
