For Schematic Diagrams.
Note:
•  All capacitors are in μF unless otherwise noted. (p: pF) 50 
WV or less are not indicated except for electrolytics and 
tantalums.
•  All resistors are in Ω and 1/4 W or less unless otherwise 
specifi ed.
•      f  : internal component.
•  C : panel designation.
THIS  NOTE  IS  COMMON  FOR  PRINTED  WIRING  BOARDS  AND  SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
For Printed Wiring Boards.
Note:
•  X : Parts extracted from the component side.
•  Y : parts extracted from the conductor side.
•      f  : internal component.
• 
 : Pattern from the side which enables seeing.
  (The other layers' patterns are not indicated.)
•  Indication of transistor.

Parts on the parts face side seen from   
the pattern face are indicated.
Parts on the pattern face side seen from   
the parts face are indicated.

CSP (Chip Size Package) 
Lead layout of conventional IC 
Note: The components identifi ed by mark 0 or dotted 
line with mark 0 are critical for safety. 
 
Replace only with part number specifi ed.
Caution:

Pattern face side: 
(Component Side)
Parts on the parts face side seen from   
the pattern face are indicated.
Parts on the pattern face side seen from   
the parts face are indicated.
•  MAIN board is multi-layer printed board.
  However, the patterns of intermediate-layers have not 
been included in diagrams.
•  A : B+ Line.
•  Voltages and waveforms are dc with respect to ground 
under no-signal conditions.
  no mark : POWER ON
       
*
  : Impossible to measure
•  Voltages are taken with VOM (Input impedance 10 MΩ).
  Voltage variations may be noted due to normal production 
tolerances.
•  Waveforms are taken with a oscilloscope.
  Voltage variations may be noted due to normal production 
tolerances.
•  Circled numbers refer to waveforms.
•  Signal path.
  N  : WIRELESS LAN
  F 
: AUDIO
  O  : USB
•  The voltage and waveform of CSP (chip size package) 
cannot be measured, because its lead is different from 
that of conventional IC.
