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.  
WARNING  
Do not expose the unit to rain or an environment where it may be  
splashed by water or other liquids, as doing so may result in fire or  
electric shock.  
CAUTION  
Indicates a potentially hazardous situation which, if mishandled, could  
result in moderate or minor personal injury, and/or property damage.  
• 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.  
WARNING  
Indicates a potentially hazardous situation which, if mishandled,  
could result in death or serious personal injury.  
• Note correct polarity (positive and negative orientation) when  
connecting the power supply cable. Incorrect connection may cause  
failure of other equipment connected.  
• 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.  
• 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.  
• 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.  
• 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.  
• 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.

Rules. These limits are designed to provide reasonable protection  
against harmful interference in a residential installation. This  
equipment generates, uses and can radiate radio frequency  
energy and, if not installed and used in accordance with the  
instructions, may cause harmful interference to radio  
communications. However, there is no guarantee that  
interference will not occur in a particular installation. If this  
equipment does cause harmful interference to radio or television  
reception, which can be determined by turning the equipment off  
and on, the user is encouraged to try to correct the interference  
by one or more of the following measures:  
• 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  
• Reorient or relocate the receiving antenna.  
• Increase the separation between the equipment and receiver.  
• Connect the equipment into an outlet on a circuit different from  
that to which the receiver is connected.  
• Consult the dealer or an experienced radio/ TV technician for  
help.  
• 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.

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.  
Attach the dome cover  
with its projection aligned  
with the mounting hole of  
the camera section.  
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.

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.  
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.  
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.  
• 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.
