THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS.
(In addition to this, the necessary note is printed in each block.)
• 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.

• 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

Note 1: When the complete MAIN board is replaced, the destination
setting is necessary. Refer to “NOTE THE MAIN BOARD
OR SYSTEM CONTROLLER (IC501) REPLACING” on
page 4.
Note 2: When the complete BT board or complete MAIN board (in-
cluding BT board) is replaced, it is necessary to confi rm op-
eration. Refer to “BLUETOOTH FUNCTION CHECKING
METHOD USING A CELLULAR PHONE” on page 7.
