THIS NOTE IS COMMON FOR PRINTED WIRING
BOARDS AND SCHEMATIC DIAGRAMS.
Note on Printed Wiring Boards :
• Through hole is omitted.
• b : Pattern on the side which is seen.

Note on Schematic Diagram :
• Caution when replacing chip parts.
New parts must be attached after removal of chip.
Be careful not to heat the minus side of tantalum capacitor,
because it is damaged by the heat.
• All capacitors are in µF unless otherwise noted. pF : µµF 50 WV
or less are not indicated except for electrolytics and tantalums.
• All resistors are in Ω and 1/16 W or less unless otherwise
specified.
• Chip resistor are 1/10 W or 1/16 W unless otherwise noted.
