Notes on Operation

Power supply

Power is supplied to the camera module via the

IEEE1394b cable connected to a PC. If the power supply

is insufficient, use the DC-700/700CE that supplies

stable power with less ripple or noise.

Foreign bodies

Be careful not to spill liquids, or drop any flammable or

metal objects in the camera body.

Locations for operation and storage

Avoid operation or storage in the following places.

• Extremely hot or cold locations. Recommended

temperature range is 0°C to 40°C (32°F to 104°F)

• Locations subject to strong vibration or shock

• Near generators of strong electromagnetic radiation

such as TV or radio transmitters

Care

Use a blower to remove dust from the surface of the lens

or optical filter. Clean the exterior with a soft, dry cloth.

If the camera is very grimy, apply a cloth soaked in a

mild detergent then wipe with a dry cloth. Do not apply

organic solvents such as alcohol which may damage the

finish.

Note on laser beams

Laser beams may damage a CCD. You are

cautioned that the surface of a CCD should not be

exposed to laser beam radiation in an environment

where a laser beam device is used.

Phenomena Specific to

CCD Image Sensors

The following phenomena that may appear in images are

specific to CCD (Charge Coupled Device) image

sensors. They do not indicate malfunctions.

White flecks

Although the CCD 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 CCD 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

Vertical smear

When an extremely bright object, such as a strong

spotlight or flashlight, is being shot, vertical tails may be

produced on the screen, or the image may be distorted.

Aliasing

When fine patterns, stripes, or lines are shot, they may

appear jagged or flicker.
