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.
• : Internal component.
f
• : Pattern from the side which enables seeing.
(The other layers' patterns are not indicated.)
Caution:
Pattern face side: Parts on the pattern face side seen
(Conductor Side) from the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(Component Side) the parts face are indicated.
Caution:
Pattern face side: Parts on the pattern face side seen
(SIDE B) from the pattern face are indicated.
Parts face side: Parts on the parts face side seen from
(SIDE A) the parts face are indicated.
• MB-1610 and BAR-AMP boards are multi-layer printed
board. However, the patterns of intermediate layers have
not been included in diagrams.
• Indication of transistor.

Note 1: When the complete MB-1610 board is replaced,
refer to "NOTE OF REPLACING THE MB-1610
BOARD OR WLAN/BT COMBO CARD" on page
4.
Note 2: When the complete BAR-AMP board is replaced,
refer to "BOND FIXED POSITION OF ELEC-
TRICAL PARTS" and "SPREADING OF COM-
POUND" on page 8.
Note 3: Among mounted electrical parts on each boards, only
parts that are described in the electrical parts list can
be replaced for repair.
The parts that are not described in the electrical parts
list cannot be replaced with single for repairing.

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.
• C : Panel designation.
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.
• A : B+ Line.
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.
no mark : POWER ON
• Voltages are taken with VOM (Input impedance 10 M).
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.
