Power supply

The power of this model is supplied by network cable.
Use the network cable UTP, category-5.
Damage to the network cable may result in fire or electric shock.

Transportation

Always turn off the power when carrying.
When transporting the camera, repack it as originally packed at the factory or 
in materials of equal quality.

Cleaning

Use a blower to remove dust from the lens.
Use a soft, dry cloth to clean the external surfaces of the camera. Stubborn 
stains can be removed using a soft cloth dampened with a small quantity of 
detergent solution, then wipe dry.
Do not use volatile solvents such as alcohol, benzene or thinners as they may 
damage the surface finishes.

Note on laser beams

Laser beams may damage image sensors. You are cautioned that the surface of image 
sensors should not be exposed to laser beam radiation in an environment where a laser 
beam device is used.

Phenomena Specific to Image Sensors

The following phenomena that may occur in images are specific to image 
sensors. They do not indicate a malfunction.

White flecks

Although the image sensors are produced with high-precision technologies, fine 
white flecks may be generated on the screen in rare cases, caused by cosmic rays, 
etc.
This is related to the principle of image sensors and is not a malfunction.
The white flecks especially tend to be seen in the following cases:
- when operating at a high environmental temperature
- when you have raised the gain (sensitivity)
- when using the slow shutter

Aliasing

When fine patterns, stripes, or lines are shot, they may appear jagged or flicker.

About the imaging conditions

When Auto Iris is set to On, resolution may be unsatisfactory. In this case, set 
Auto Iris to Off.
