Changing a lens
Perform the following steps to change a lens:
• Point the camera downwards. This to minimize possible deposit of dust on the inside of the
camera when the lens is removed.
• Remove the old lens by turning it
counter-clockwise (1).
Do not release the back-focus locking ring (2),
otherwise you may have to readjust the
back-focus of the camera.
Caution: Never touch the CCD sensor which is
located at the inside of the camera. Only use clean,
dry air to blow particles from the surface of the sensor.
• Mount the new lens by turning it clockwise
onto the lens mount of the camera.
• Direct the camera at the object or area to be monitored (6).
• Tighten the knob (3) and screw (4) when the camera is in position.
• Adjust the focus ring (1) of the camera lens to obtain an optimal image sharpness.
Remark: If an auto-iris lens is used, connect the auto-iris cable to the camera (5).
