For Schematic Diagrams
• All capacitors are in
μ

F. 50 V or less are not indicated except for electrolytics
and tantalums.
• Chip resistors are 1/10 W unless otherwise noted.

• Caution when replacing chip parts.
New parts must be attached after removal of chip.
Be careful not to heat the minus side of tantalum capaci-
tor, Because it is damaged by the heat.
• Some chip part will be indicated as follows.

• Constants of resistors, capacitors, ICs and etc with XX
indicate that they are not used.
In such cases, the unused circuits may be indicated.
• Parts with differ according to the model/destination.
Refer to the mount table for each function.
• All variable and adjustable resistors have characteristic
curve B, unless otherwise noted.
• Signal name

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.
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
0
sont critiques pour la sécurité.
Ne les remplacer que par une pièce
portant le numéro spécifié.
When indicating parts by reference
number, please include the board name.
