1)  Approx 20% higher than in normal mode
2)  AV copying and SAT recording: approx. 15% higher; SAT radio: same as in normal mode
3)  Approx. 25% lower than in normal mode
4)  Lower than in normal mode, with superimposed sawtooth waveform
5)  Setting the voltage D140/142/150 with R1896 (with beam current 0) to the values shown in the table automatically sets the H output

stage voltages to their correct values.
