Precautions for Replacement of Imager
• 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.
In addition, ensure that the receiver is not covered with
dusts nor exposed to strong light.
The components identified by mark
0
or dotted line with
mark
0
are critical for safety.
Replace only with part number specified.
Les composants identifiés par une marque

sont
critiques pour la sécurité.
Ne les remplacer que par une pièce portant le numéro
spécifie.
