Note on Schematic Diagram:
•All capacitors are in ∝F 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 specified.
•C : panel designation.
•A : B+ Line.
•Power voltage is dc 3.7 V and fed with regulated dc power supply from CN901 pin 1 and pin 2on the MAIN board.
•Voltages are dc with respect to ground under
