alcohol, benzene, thinner, or other chemicals because such chemicals may damage or discolor the paint
and indications.

Cleaning the sensor window

Avoid cleaning the sensor window if possible. Keep lens cap closed as long as no lens is attached, avoid
touching the sensor. If necessary, clean the sensor window using compressed air. If further cleaning is
required, use lint-free, ESD-safe cloth wiper. Avoid cloth that could generate static charge or that could
scratch the window. The camera should be cleaned in an ESD-safe area. The person performing cleaning
should be earthed.

Connectors

Take care when handling the camera so that no damage can be done to the connectors. Prevent foreign
objects in the connectors.

Handle carefully

Always transport the camera in its original packaging. Do not drop the equipment or allow it to be
subject to strong impact or vibration, as such action may cause malfunctions. Do not damage the
connection cable, since this may cause wire breakage. If the camera is not in use, attach the lens cap to
the camera to protect the image pickup surface. If the equipment is not to be used for a long duration,
turn off power to the camera for safety.

Check compatibility of lens

Depending on lens and lighting an image can be reflected as a ghost into the imaging area. This is not a
fault of the camera. Depending on the lens the performance of the camera might not be brought out
fully due to deterioration in resolution and brightness in the peripheral area, aberration and other side
effects. Be sure to check lens and lightning you plan to use for compatibility with your camera. When
installing a lens in the camera make sure that it is not tilted. Use a mounting screw free from defects and
dirt. Otherwise the lens might not be removable from the camera.
Install lenses with a protrusion from bottom of the screw equal or less than 10 mm. If a lens does not
fulfill this condition it might damage the camera when trying to be installed.
