One of the indicators that correspond to the adjustment
item chosen by the SELECT button
m
lights up.
Adjustment by the ADJUST +/- buttons

is possible
while the indicator is lit.
All indicators light up instantly (for about 0.25 seconds)
when the stored conditions are cleared.

AC IN connector
[[] VIDEO OUT (video output) connectors (BNC)
Use these connectors to distribute the video signal fed to
this unit to another monitor.
When cables are connected to these connectors, the
75-ohm termination of the VIDEO IN connectors
[!]
is
released automatically.
[!]
VIDEO IN (video input) connectors (BNC)
Accept RGB video signals (O.714Vp-p, positive).
When no external sync signal is applied, an internal sync
signal (0.286Vp-p, negative) must be added to the G
(green) signal.
I~Mtj
The optimum display may not be obtained when using
computer or video board of high output level
(approx.1.0Vp-p). In such a case, adjust the display by
lowering the contrast, or use computer or video board of
adequate output level.

SYNC OUT (sync output) connectors (BNC)
Use these connectors to distribute the external sync
signal fed to this unit, to another monitor.
When cables are connected to these connectors, the
termination of the SYNC IN connectors
[1]
is released
automatically.
m:ma
• Use a coaxial cable that is less than 3 meters long and
of 75 ohms impedance to connect the VIDEO OUT and
SYNC OUT connectors. If the cable is too long, or if
its impedance is incorrect, or if several monitors are
connected in cascade, the picture may be noisy with
horizontal and vertical lines .
• When not distributing signals to another monitor,
disconnect the cables from the VIDEO OUT and SYNC
OUT connectors .
• If the BNC connector of the signal distributing cable is
not adequate, the termination impedance may not be
disconnected properly. Always use the cable with
adequate BNC connectors.
TIl
SYNC IN (sync input) connectors (BNC)
Accept external sync signals (2 to 5Vp-p, positive or
negative).
HD : for horizontal drive pulse or composite drive pulse
VD : for vertical drive pulse
When an external sync signal is applied, the monitor is
switched automatically from the internal sync mode to
the external sync mode. When the G signal contains the
sync signal, however, the hue of the monitor may be
changed. In this case, disconnect the external sync
signal and apply the internal sync signal mode.
[g]
75Q/2kQ selector
Switches the impedance of the SYNC IN connectors
termination to 75Q or to 2kQ. When external sync
signals are input, normally set this selector to the 75J:2
position. If good synchronization cannot be obtained. set
this selector to the 2kQ position.
