• U : B+ Line.
• Power voltage is dc 9V and fed with regulated dc power
supply from external power voltage jack (J301 on the
BASE MAIN board).
• Power voltage is dc 12V and fed with regulated dc power
supply from modular jack (MJ101 on the BASE MAIN
board) with 100 Ω in series.
• Power voltage is dc 3.6V and fed with regulated dc power
supply from battery jack (HAND MAIN board).
• Voltages and waveforms are dc with respect to ground
under no-signal conditions.

• Voltages are taken with a VOM (Input impedance 10 MΩ).
Voltage variations may be noted due to normal produc-
tion tolerances.
• Waveforms are taken with a oscilloscope.
Voltage variations may be noted due to normal produc-
tion tolerances.
• Circled numbers refer to waveforms.
