CAUTION
Do NOT connect/disconnect connectors with power ON.
Before connecting/disconnecting connectors, make sure to check if the system is
powered OFF. Doing so with power ON may cause a damage or an electric shock
accident.
Do NOT give a strong shock/impact against the camera-head.
Avoid giving a strong shock against the camera head. The camera-head might be
damaged.
Do NOT pull/swing the cable forcefully.
Do not pull strongly the camera cable/camera-head nor swing it. The stress from pulling
or swinging may cause damage in the coating of the cable, or breaks in the inside wires.
In carrying the camera around, be sure to disconnect connection cables/lines beforehand.
Otherwise, the connection cable(s)/line(s) might be damaged, causing a fire or an
electric shock accident.
If the camera is operated in the electromagnetic field, there may be cases where beat
noises (vertical, horizontal, or oblique stripes) may appear in the video output. In that
case, take preventive measures on the electromagnetic-wave generating source so that
the camera do not receive the interference by the electromagnetic-wave. Take extra
precautions against electromagnetic-wave-interference if the camera is used with a
servomotor, inverter, or other electromagnetic-wave-generating equipment.
When the camera is not in use, put a lens or a lens-cap onto the camera head so that the
image pickup plane of CCD is protected from dust, foreign object, or other flaw-causing
object. If the glass plane (image pickup plane) gets dirty, clean it with a cotton swab.
When it needs to be cleaned with a cleaner, be sure NOT to use any organic solvent other
than ethyl alcohol. As a countermeasure against condensation, when the camera is
moved from a warm place to a cold place, take appropriate precautions to prevent
condensation from forming on the camera.
Avoid placing the camera where it is splashed with water or any other fluids. Operating
the camera with its inner parts/circuits in wet condition may cause a damage or an
electric shock accident.
