8. Camera Input Connectors (CAMERA IN 1–4)
(BNC type)
The camera signals are supplied to these connectors.
Notes : In this unit, the specific control signal is added
on the Vertical Blanking for VTR recording so that any
other control signals located on the Vertical Blanking
can not be acceptable for this unit.
The picture will be disturbed in the switching (sequen-
tial) due to the non-synchronized input connector.
9. Camera Output Connectors (CAMERA OUT)

The playback signal from VTR is supplied to this con-
nector. When connecting a coaxial cable for the
Playback Output Connector, the high impedance video
loop is automatically selected. At all other times this
connector is automatically terminated with 75 ohms.
12. Recording Output Jack (REC OUT) (Pin-jack)
The recording signal for the VTR is provided via this
connector.

Notes:
Be sure to supply the audio signal of the Camera 1 –
4 to the correct Microphone Connector 1 – 4.
The maximum cable length for the microphone exten-
sion should be within 20 m.
18. Ground Terminal (SIGNAL GND)
19. Power Cord

Picture Stability Switch ON/OFF
For reasons of the specifications of this set, reproduced
pictures will swing vertically if three cameras are con-
nected (with one channel left unconnected) for record-
ing.
If a recording is made when there is a channel to which
no camera is connected, the picture of a channel differ-
ent from the unconnected channel may be displayed in
quad mode reproduction.
The above can be avoided by setting the picture stability
switch (SW901) to ON.
The switch is originally set to OFF in the factory before
shipment.
ON: Picture stability ON
OFF: Picture stability OFF
Caution
The table below applies in cases where recordings are
made under the following settings using a video tapere-
corder having the T/V record function.
If there is a channel to which no camera is connected,
VTR's T/D display and the picture stability switch may
be set to ON so that VTR's T/D will be displayed on the
black screen of the unconnected channel in reproducing
recorded pictures as mentioned above.

INSTALLATIONS
Switching the microphone sensitivity
When using the microphone, set the Microphone
Sensitivity Switch inside this unit to the suitable position
as shown below according to the sensitivity of the micro-
phone.
Initially, –60 dBs are selected at the factory.
Microphone 1 : SW501
Microphone 2 : SW502
Microphone 3 : SW503
Microphone 4 : SW504
0 side setting : Sensitivity of the microphone is approx.
0 dB.
–60 side setting : Sensitivity of the microphone is
approx. –60 dB.

Note on Installation :
Be sure to have your dealer install the set. Make sure
that the power switch is OFF and that the power plug
has been pulled out of the electrical outlet in advance.
Precautions for Installation :
keep a space of 5 cm or more.
Keep a space of 5 cm or more on the sides t rear and
top of the set.
Install the set at a place free of noise.
Noise may interfere if the cables of the set are close to
the house electric wires. In such a case, rewire the set
or change its place.

Mounting into the Rack
When this unit is to be mounted on a EIA 19-inch rack,
use Rack Mount Angles (provided) and 8 Rack Mount
Angle Fixing Screws (provided, M4 X 10)
1. Turn off the power of this unit.
2. Remove four rubber feet by removing four screws on
the bottom of this unit.
3. Place the Rack Mount Brackets on both sides of this
unit and tighten with the eight supplied screws.
4. Install the unit with Rack Mount Brackets in the rack by
using four screws (local procurement).
Cautions :
Do not block the ventilation opening or slot on the cover
to prevent the unit from rising temperature.
Always keep the temperature in the rack within 50°C.
Secure the rear of the unit to the rack by using addition-
al mounting angles (procured locally) when the vibration
is added to the rack.
Remove four Rubber Feet.
Fasten four screws.
