4. 30 SECTION 5 Handling Instructions 5 1 AN Electrostatic Discharge The Fairchild Imaging Osprey camera uses TDI technology in a CCD base and as all such devices has some limited inherent susceptibility to electrostatic discharge ESD All reasonable and customary design steps have been taken to provide ESD protection circuitry Electrostatic charge placed at the sensor could cause charging of the chip which in some situations might not be readily dissipated and minor impact on performance might be temporarily experienced Therefore do not insert your finger or any other object into the lens mount barrel 9 2 AN Preventing ESD Damage e Please be certain to ground yourself prior to handing the camera e Ensure that your working environment is grounded including conductive floor mats e Do not touch the window of the imager 5 3 AN Protecting Against Dust Oil and Scratches e Be certain to avoid dust buildup on the sensor window where it could block the optical path e By not touching the surface of the sensor you avoid introducing oil and avoid scratching the sensor window Again you should not insert anything into the lens mount barrel 5 4 AN Cleaning the Sensor Window e Use compressed air to blow off particulate e lf for some reason cleaning of the sensor window is required use lens wiping cloth with a small amount of eyeglass cleaning fluid Do not use solvent as it may smear the sensor window Fairchild
