Safety symbols and messages are used in this manual to prevent bodily injury and property damage which  
could result from mishandling. Before doing anything else, read this section first so you are thoroughly aware  
of the potential safety hazards as well as understanding the safety symbols and messages.  
Do not expose the unit to rain or an environment where it may be  
splashed by water or other liquids, as doing otherwise may result in  
fire or electric shock.  
WARNING  
Indicates a potentially hazardous situation which could result in death or  
WARNING  
serious personal injury if ignored or mishandled.  
• 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 and causing personal injury.  
• 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.  
• Should any of the following irregularities be found during use, immediately switch off the power, disconnect  
the power supply cord from the AC outlet 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 from the unit.  
• If water or a foreign object enters the unit.  
• If the unit falls or the unit case breaks.  
• If the power supply cord is damaged (exposure of core or disconnection).  
• If no image is displayed on the screen.  
• Do not open nor modify the unit’s case to prevent a fire or electric shock because there are high voltage  
components inside the unit. Refer all inspection, adjustment and repair work to the dealer from where the  
unit was purchased.  
• Do not insert or drop metal pieces or flammable materials into the unit’s ventilation slots 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.  
Indicates a potentially hazardous situation which could result in  
moderate or minor personal injury, and/or property damage if ignored  
or mishandled.  
CAUTION  
• 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.  
• Leave the unit’s installation to the dealer from where the unit was purchased because the installation  
requires expert knowledge. Inadequate installation may cause the unit to fall, possibly resulting in personal  
injury.  
• Do not hang from the unit, as the unit may fall, possibly resulting in personal injury.

2. GENERAL DESCRIPTION  
The C-CV14-2 Color Camera is a high-resolution surveillance camera equipped with a 1/4” CCD. It is  
designed to operate on 24V AC or 12V DC. Since its 2X vari-focal, auto-iris lens is built inside the camera, its  
angle of view can be manually adjusted.  
3. HANDLING PRECAUTIONS  
• Do not point the camera toward the sun or other strong lighting or reflected light.  
• Avoid jarring or striking the camera, as the camera may fail.  
• Install the camera in locations where the temperature range does not exceed –10°C to +50°C, and no dew  
condensation is formed.  
• To clean, wipe with a soft, dry cloth. Never use benzene, thinner or chemically-treated towel to avoid  
damage to the camera’s finish.  
• To clean the lens, use a camera blower or lightly wipe with lens cleaning paper.  
• Picture quality may suffer if camera cables are wired close to other electrical equipment, such as fluorescent  
lamps. In such cases, reroute the wiring.  
• Monitor screen pictures may become distorted or roll if the camera is used in locations influenced by strong  
electrical or magnetic fields from television transmission antennas, motors or transformers. In such cases,  
install the cables inside sheet steel cable conduit.  
• Use the external power supply unit of the following rating when the camera is operated on 12 V DC.  
12 V DC, over 1.0 A

7. ADJUSTMENT  
1. Switch on the camera power after completing camera connections.  
Power is supplied to the camera.  
2. Normally,set the Shutter Speed switch to "1/60"(NTSC) or "1/50"(PAL) position.  
Flickering of the picture may interfere with the view under fluorescent lamp in the area with power frequency  
of 50 Hz(NTSC) or 1/60 Hz(PAL). In such cases, set the switch to "1/100"(NTSC) or "1/120"(PAL) position,  
and the image free from flickering can be obtained.  
Note  
If the Flicker Reduction switch of the Mode Setting 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.  
3. Connect the monitor to the Video Output terminal to permit a picture to be viewed on the monitor.  
4. Adjust the camera angle.  
Loosen the camera mounting bracket’s lock lever to point the camera to the desired direction, then retighten  
the lock lever to fix the camera securely.  
5. Adjust the angle of view with the Zoom ring and adjust the focus with the Focus ring for the best possible  
picture reproduction.  
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 of the Mode setting  
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 of the  
Mode setting switch to the ON position. Be sure to switch it back to the OFF position after completing lens  
adjustment.  
6. Attach the Lens cover to the camera after completing all necessary adjustments.  
Note: Refer to p. 7; Lens Cover Attachment and Detachment.

8.1. Adjustment Switch  
Set this switch when adjusting the lens focus.(Provides the same effect as when using the ND filter.)  
OFF ON  
Standard position :  
Set to OFF after lens adjustment completion. Set to this position during normal use.  
Adjustment position (during adjustment) :  
OFF ON  
Use this position when focusing the lens. If the focus is adjusted for a subject under  
good lighting conditions, the subject may go out of focus when conditions become  
dark. Set the Adjustment switch to ON only when performing focus adjustment.  
Note: The color of the screen may periodically vary under fluorescent lighting when the  
Adjustment switch is set to ON.  
8.2. Backlight Compensation Switch  
Set this switch so that the subject is not displayed in black when backlit.  
OFF ON  
Standard position :  
Set to this position during normal use. Backlight Compensation function does not  
operate when the switch is set to this position.  
OFF ON  
Backlight Compensation position (when backlit) :  
This position prevents images from being displayed in black when the image is  
backlit.  
8.3. Shutter Speed Switch  
Set this switch to the ON position when annoying screen image flicker is detected.  
OFF ON  
Standard position :  
Set to this position during normal use.  
Shutter Speed position :  
OFF ON  
Annoying screen flicker may result under fluorescent lighting in areas operating with a  
power frequency of 50 Hz (NTSC) or 60 Hz (PAL). In such cases, set the Shutter  
Speed switch to the ON position to permit a flicker-free picture to be viewed.  
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.
