A
: B+ Line.
• Power voltages is dc 14.4V and fed with regulated dc
power supply from ACC and BATT cords.
• Voltages and waveforms are dc with respect to ground
under no-signal (detuned) conditions.

( ) : CD PLAY
• 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.

Note:
When the complete MAIN board is replaced, it is nec-
essary to replace knob (VOL) (SV) assy simultane-
ously. Also, the destination setting, Bluetooth operation
check and Bluetooth information writing are necessary.
Refer to “DESTINATION SETTING METHOD” on
page 4, “BLUETOOTH FUNCTION CHECKING
METHOD USING A CELLULAR PHONE” on page
7 and “BLUETOOTH INFORMATION WRITING
METHOD” on page 8.
