C : panel designation. U : B+ Line. Power voltage is dc 3.6 V and fed with regulated dc power supply from external power voltage jack (CN301). Voltages and waveforms are dc with respect to ground under no-signal conditions. no mark : Talk Voltages are taken with a 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. Signal path. N : RX O : TX P : bell
