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.
イメージャ交換時の注意
・ イメージャを交換した場合は，カメラ部の全調整を行って
ください。
・ イメージャは構造上，静電気により破壊される恐れがある
ため，MOS ICと同様に注意して取り扱ってください。
また，受光部にはゴミの付着，および強い光がはいること
のないように注意してください。
The components identified by mark
or dotted line with mark are critical
for safety.
Replace only with part number speci-
fied.
Les composants identifiés par une mar-
que sont critiques pour la sécurité.
Ne les remplacer que par une pièce
portant le numéro spécifié.
