BNC connectors :
Connect double shielded coaxial cables with BNC connector at the
monitor ends. This monitor has five (5) BNC input connectors,
however, number of cables required depends on the graphics board
sync signal output.
(1)
Sync on Green signal : Three (3) cables
(2)
H/V composite signal : Four (4) cables
(3)
H, V separate signal : Five (5) cables
If the graphics board supplies more than one type of sync signal, use
less number of cables. See “COMPATIBILITY” section for details.
(4) Turn monitor power on first, then computer.
(5) Start Your System.
When display comes on adjust the screen size and location. Display

on the front.
Display size may also be adjusted by H. and V. size controls. Do not
exceed 290 mm wide and 220 mm height as the monitor quality can
be reduced outside these dimensions.
Display location on the screen and the size may change when you
switch one application software to another one.
Brightness control shall be set so that the background raster is not
seen. Set Contrast control to a comfortable foreground brightness.
