Precautions for Replacement of Imager
• If the imager has been replaced, carry out all the adjustments
• If the imager has been replaced, carry out all the adjustments
for the camera section.
• As the imager may be damaged by static electricity from its
structure, handle it carefully like for the MOS IC.
In addition, ensure that the receiver is not covered with dusts
nor exposed to strong light.
The components identified by mark
