2.3 Connecting the Composite Video Signal to the

Monitor

VIDEO B
IN
OUT
There are four BNC connectors (Fig. 1 item - 11), located on
the rear of the monitor, for the composite VIDEO A/ VIDEO
B inputs and outputs.
Note:
The impedance is automatically set to 75 ohm by the input
of a signal on the input connector while operating in a
single connection mode. However, if a cable is connected
to the output connector, the connection is placed into the
open status by the multiple connection and high impedance
is automatically selected.
CAUTION:
Do not leave an unused cable connected to the monitor. If
a single cable is used, then it must be connected to the
input connector for the 75 ohm auto-termination selector to
function properly.
Note:
Ensure that the Composite Video-Y/C switch (Fig. 1 item -
7), located on at the front of the monitor, is selected to the
correct position.
2.4 Connecting the Y/C Signal to the Monitor
There are two mini-DIN type connectors (Fig. 1 item - 12) for
the Y/C IN (Input) and OUT (Output) for looping-through to
other video monitors.
Note:
Ensure that the Composite Video-Y/C switch (Fig. 1 item -
7), located on at the front of the monitor, is selected to the
correct position.

The Y/C IMPEDANCE switch (Fig. 1 item - 13) selects the S-
VIDEO impedance. Set the switch to the 75 Ω Ω position when
only one monitor is used or when the monitor is used as the
last monitor in a chain. Set to HIGH when another monitor is
connected to the Y/C OUT connector for loop-through

operation.

Connecting Audio to the Monitor

There are two RCA phone type
connectors (Fig. 1 item - 10) one for
the audio input and the other for
looping through to other video
monitors.
Note:
The audio in/out is not
dependent upon the VIDEO
input.
3 OPERATION
VOLUME control (Fig. 1 item - 1)
Adjust the VOLUME control for the appropriate audio level.
Turn clockwise to increase sound and counterclockwise to
decrease it.
If the audio input is not used, turn to minimum.
SHARPNESS control (Fig. 1 item - 2)
Adjust the SHARPNESS control for the desired overall
sharpness. Turn clockwise to increase picture sharpness and
counterclockwise to decrease it.
CONTRAST control (Fig. 1 item - 3)
Adjust the CONTRAST control for the desired overall
contrast.
Turn clockwise to increase picture contrast and
counterclockwise to decrease it.
BRIGHTNESS control (Fig. 1 item - 4)
Adjust the BRIGHTNESS control for the desired overall
picture or display brightness.
Turn clockwise for more brightness and counterclockwise for
less.
