Thank you for purchasing TOA's Color Dome Camera.
Please carefully follow the instructions in this manual in order to ensure long, trouble-free use of your color dome camera.
1. SAFETY PRECAUTIONS
• Before installation or use, be sure to carefully read all the instructions in this section for correct and safe operation.
• Make sure to observe the instructions in this manual as the conventions of safety symbols and messages regarded as very important
precautions are included.
• We also recommend you keep this instruction manual handy for future reference.
• Use the unit only with the voltage specified on the unit. Using a
voltage higher than that which is specified may result in fire or
electric shock.
• Use screws and bolts that are appropriate for the ceiling's or wall's
structure and composition. Failure to do so may cause the unit to fall,
resulting in material damage and possible personal injury.
• Install the unit only in a location that can structurally support the
weight of the unit and the mounting bracket. Doing otherwise may
result in the unit falling down and causing personal injury and/ or
property damage.
• Do not install the unit outdoors since it is designed for indoor use. If
installed outdoors, the aging of parts causes the unit to fall down,
possibly resulting in personal injury. Also, when it is exposed to rain,
an electric shock may result.
• To prevent a fire or electric shock, never open the unit case nor
modify the unit as there are high voltage components inside the unit.
Refer all servicing to your nearest TOA dealer.
• Should any of the following irregularity be found during use,
disconnect the power supply and contact your TOA dealer. Do not
attempt to further use the unit because a fire or electric shock may
result.
· If you detect smoke or a strange smell coming form the unit
· If water or any metallic object gets into the unit
· If the unit falls, or the unit case breaks
· If the power supply cord is damaged (exposure of the core,
disconnection, etc.)
· If no image appears
• Do not insert nor drop metallic objects or flammable materials in the
ventilation slots of the unit's cover, as this may result in fire or electric
shock.
• Have the unit periodically checked by the dealer from where it was
purchased. Should the unit or its mounts corrode or structurally
deteriorate, the unit could fall down, possibly resulting in personal
injury.
• Avoid installing the unit in humid or dusty locations, in locations
exposed to the direct sunlight, near the heaters, or in locations
generating sooty smoke or steam as doing otherwise may result in
fire or electric shock.
• Note correct polarity (positive and negative orientation) when
connecting the power supply cable. Incorrect connection may cause
failure of other equipment connected.
• Leave the installation of the unit to your TOA dealer because the
installation requires expert experience and skills. If the unit falls, this
could cause personal injuries.
• Do not hang down from the camera as this may cause it to fall down
or drop, resulting in personal injury and/ or property damage.
• Disconnect the power supply, and unplug the power supply plug from
the AC outlet for the safety purposes when cleaning or leaving the
unit unused for long periods of time. Doing otherwise may cause a
fire or electric shock.

3. HANDLING PRECAUTIONS
• Do not direct the camera lens to the sun or strong lighting or light
reflection.
• Do not give the camera a great shocks or vibration, as this will
damage the camera.
• It is recommended that the camera be always used in locations
where the ambient temperature ranges from -10°C to +50°C and
humidity levels of less than 90% to ensure that no condensation is
formed.
• To clean, wipe with a dry soft cloth. Never use benzene, thinner or
chemically processed towel as the unit's plastic or other parts may be
deformed or discolored.
• When dust has settled on the camera's lens, lightly clean using a
commercial camera blower or cleaning paper.
• Installing the camera cables in close proximity to fluorescent lamps
or other electrical appliances can downgrade the picture quality. In
such cases, change the wiring.
• If there is a strong electric or magnetic field near the camera, such as
television transmission antennas, motors or transformers, this may
distort or roll the monitor picture. In such cases, run the entire wiring
route through metal conduit tubing.
• Do not install the camera in locations where solvents or chemicals
are used as the camera's dome cover may be deformed or
discolored.
• Use the external power supply unit of the following rating.

5. INSTALLATION
2. GENERAL DESCRIPTION
The C-CV202-3 Color Dome Camera is an indoor-use camera and is
equipped with a high-resolution camera and lens. It is designed to
operate on 12 V DC, which is supplied by an external power supply
unit. Since its 2X vari-focal, auto-iris lens is built inside the camera, its
angle of view can be manually adjusted.

4. Mount the camera section to the ceiling using 2 mounting screws.
Because the mounting screws are not supplied with the camera,
prepare appropriate screws for the application. (Use screws that
are over 4 mm in nominal diameter and longer than 25 mm.)
5. Attach the dome cover to the camera section after completing all
necessary adjustments.
Insert the dome cover to the camera section, then turn it clockwise
until it locks into place.
After attaching the dome cover, fit it using a supplied dome cover
fixing screw.
When detaching the dome cover, first remove the screw, then
detach the dome cover.
Note
Do not forcefully tighten the screw. Extreme force is applied to the
screw and the screw could not be removed, as this may cause the
dome cover not to become detached.
1. Switch on the power supply of 12 V DC after completing camera
connections.
The power is supplied to the camera.
2. Connect the monitor to the Monitor Output terminal to permit a
picture to be viewed on the monitor.
Note
When the monitor output terminal is connected, a video signal
cannot be output to the video output terminal.
3. Set the Shutter Speed switch to ON if light flicker is annoying.
Light flicker may interfere with the view under fluorescent lamps in
the area where power frequency is 50 Hz. In such cases, set the
Shutter Speed switch to "ON" position, and the image free from
flickering can be obtained.
Note
If the Shutter Speed switch is set to the ON position, sensitivity is
reduced compared to operation in the OFF position. When using
the camera in a dark location, or where light flicker is not an
annoyance, set the switch to the OFF position.
4. Adjust the camera angle.
Camera angle can be adjusted for up to 60°(± 30°) for horizontal
rotation, and between 0 °and 70° for vertical rotation.
5. Adjust the angle of view with the Zoom ring and adjust the focus
with the Focus ring for the best possible picture reproduction. After
lens adjustment completion, tighten both the Zoom ring fixing screw
and the Focus ring fixing screw.
Notes
• Since the Iris control (for sensitivity adjustment) is factory-preset to
an optimum position for general use, avoid tampering with it in
normal conditions. Turning the control unnecessarily could cause
reduced picture quality or equipment failure. When the Iris control
needs to be readjusted to match a specific subject, first set both the
Adjustment switch and the Backlight Compensation switch to the
OFF position, then adjust the control to an optimum level. After
adjustment, place a hand over the lens for several seconds and then
release to check the lens for correct iris operation.
• If the focus is adjusted for a subject under good lighting conditions,
the subject may go out of focus when conditions become dark. To
avoid this, adjust the lens focus after setting the Adjustment switch to
the ON position. Be sure to switch it back to the OFF position after
completing lens adjustment.
Note
If the Video output is not terminated at 75 Ω, video pictures are not
properly displayed. Make sure that the output has been terminated at
75 Ω at the connected monitor or switcher.
