SYSTEM CHECKOUT
You can check Simplex system operation immediately after
installation. While the Simplex itself requires no adjustment,
check system components such as monitors, cameras and the
video recorder for proper operation and adjustment. The sys-
tem checkout procedure involves three steps: monitor calibra-
tion, camera check and video recorder check. You need at least
two video cameras to check system operation. Make certain
that all required system connections are made. Apply power
to all system equipment.
Monitor Calibration
Calibration involves adjusting monitor display brightness and
contrast based on the standard bar pattern generated by the
Simplex system. The procedure is as follows:
1.
Press
Fdown arrow
. A bar pattern created by
the Simplex appears on the monitor.
2.
(color models only) Turn off any automatic color control
features on the monitor that might interfere with manual
adjustment.
3.
(color models only) Turn the monitor’s color level (satu-
ration) control all the way down. The display should now
be black and white.
4.
Adjust the monitor’s contrast and brightness controls so
that the eight bars progress evenly from white to black.
5.
(color models only) Turn the monitor’s color level control
to its midpoint.
6.
(color models only) Adjust the monitor’s tint (hue) con-
trol until the colors are correct. The sequence of colors from
left to right is: white, yellow, cyan, green, magenta, red,
blue and black. Press
LIVE
to exit.
The monitor is now correctly calibrated to the output of the
Simplex. While monitor adjustments can be changed to suit
the viewer, use the procedure described above
before
attempt-
ing to adjust cameras or
before
working on a display or video
quality problem. To calibrate the call monitor, connect its video
cable to the
main mon
connector on the Simplex and repeat
steps 1 through 6.
