This recessed screwdriver control should be
adjusted simultaneously to give proper vertical
height consistent with good vertical linearity.
Adjustment should be made to extend the picture
limits approximately 1/10” beyond the top and bot-
tom edges of the mask at over scanning operation.
6. Vertical Linearity (6)
This recessed screwdriver control should be
adjusted to give proper vertical linearity.
7. Focus (8)
The clearest picture is produced when this screw-
driver control is adjusted.
8. DC Restoration (10)
DC restoration circuit provides a stable reference
for the black level. Set the switch to ON position to
prevent excessive contrast and preserve shadow
detail.

CONNECTIONS
Power Cable
1. Keep the camera Power switched OFF during
installation.
2. Connect the Power Cord (16) to a 60 Hz grounded
electrical outlet 120V AC .
Video Cable
1. Use the RG-59/U (3C-2V), RG-6/U (5C-2V). RG-
11/U (7C-2V) or RG-15/U (10C-2V) coaxial cable.
2. Up to 10 monitors can be hooked up in this config-
uration before signal loss occurs. Total cable
length should not exceed 500 feet (150m).
3. Wiring Precautions
• Do not bend coaxial cable into a curve whose
radius is smaller than 10 times of its diameter.
• Never crush or pinch the cable
All these will change the impedance of the cable
and cause poor picture quality

External Sync
When a non-composite video signal is connected to
the monitor, it will be necessary to connect an external
composite sync signal to the monitor.
1. Connect the Sync Input Connector (14) on the
video monitor to the sync signal source by means
of a 75Ωcoaxial cable.
2. Set the Sync Selector Switch (13) at EXT position.
NOTE:
1. Non-composite video signal is a signal without
sync.
2. External sync should be composed of mixed H.
Sync and V. sync signals, not H. and V. drive
pulse signals. Composite Sync Level:
4.0 Vp-p (2.0 Vp-p −5.0 Vp-p)
