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 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.

• The voltage and waveform of CSP (chip size package)
cannot be measured, because its lead layout is different
from that of conventional IC.
Note 1:
When replaced the MAIN-AMP board with a new board, the
MAC address will change. Be sure to refer to “NOTICE OF
MAC ADDRESS CHANGE TO CUSTOMERS” on page 15.
Note 2:
When replaced the MAIN-AMP board with a new board, spread
the silicon grease to the touching portion between the IC6004 to
IC6007 on the MAIN-AMP board and the heatsink (AMP).

Note 3:
Among mounted electrical parts on the MAIN-AMP board, DC
JACK board, A-IN JACK board, only parts that are described in
the electrical parts list can be replaced for repairing.
In addition, even if listed in the electrical parts list, parts listed
as “Not supplied” cannot be replaced with single for repairing.
If ANTENNA board, MIC board, TOUCH-L board, TOUCH-R
board, LED-B board, LED-TL board, LED-TR board are defec-
tive, replace them with new boards. Individual electrical parts
that mounted cannot be replaced.
