Precautions for Correct Use
(3) Orientation when Installing the Amplifier Unit
(4) Maintenance and Inspection
• Do not use thinner, benzene, acetone or kerosene to clean the Sensor Head and
Amplifier Unit.
• If large dust particles adhere to the front Panel of the Sensor Head, use a blower
brush (used to clean camera lenses) to blow them off. Do not blow the dust particles
with your mouth.
• To remove smaller dust particles, wipe gently with a soft cloth. Do not use excessive
force to wipe off dust particles. Scratches on the front Panel may cause errors.
(5) Optical Axis and Detection Range
The center of the guide light and detection range are for reference only.
The center of the optical axis sometimes differs according to each Sensor Head. Dur-
ing installation, be sure to check the center of the image and the detection range on the
LCD monitor of the Amplifier Unit.
(6) Ventilation Film
• Do not peel off or probe the ventilation film with a sharp-pointed object. If you so, the
specifications of the protective structure may no longer be satisfied.
• Do not block the ventilation film. Doing so might cause the front panel to be con-
densed.
