When Installing the Unit
• This is a class A product. In a domestic environment this product may cause radio interference in which case
the user may be required to take adequate measures.
• 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.
• Avoid installing the unit in unstable locations, such as on a rickety or slanted surface. Failure to do so may
result in the unit falling and possibly causing 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.
• Only use the unit's dedicated mounting hardware. The use of mounting hardware not designated could result
in the unit falling and possibly causing personal injury.
• Do not use other methods than specified to install the unit. Extreme force is applied to the unit and the unit
could fall off, possibly resulting in personal injuries.
• Attach the safety wire to the unit. If not attached, the unit could fall off, resulting in personal injury.
• Use nuts 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.
• Tighten each nut and bolt securely. Ensure that the bracket has no loose joints after installation to prevent
accidents that could result in personal injury.
• Avoid installing the unit in locations exposed to sea breeze or corrosive gas. Mounts may become corroded,
eventually causing the unit to fall off, which could result in personal injury.
• Do not mount the unit in locations exposed to constant vibration. The mounting screws and/or bolts may be
loosened by excessive vibration, potentially causing the unit to fall, which could result in personal injury.
When the Unit is in Use
• If any of the following irregularities occurs, immediately unplug the power plug from the AC outlet and inform
the shop from where the unit was purchased. Further using the unit may result in fire or electric shock.
· If you detect smoke or a strange smell coming from 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 camera images are displayed on the monitor TV when the temperature of the camera unit is 0°C or
more.
• To prevent a fire or electric shock, never open nor remove the unit case as there are high voltage
components inside the unit. Refer all servicing to your nearest TOA dealer.
• Do not insert, or drop metallic objects or flammable materials in the ventilation slots of the unit’s cover, as
this may result in fire or electric shock.
• Do not touch the unit during thunder and lightning, as this may result in electric shock.
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.
