  • Page 9 Explanation of diagram Explanation of diagram Type numbers of transistors and ICs are indicated on the diagrams. If the position is followed by an asterisk the spare part number must always be used because the component in question has been specially selected, e.g. TR102*. Component print and coordinate system The largest PCBs have component prints and a coordinate system on both the print and the component side.
  • Page 10 Explanation of diagram Measuring conditions All DC voltages have been measured in relation to ground with a voltmeter with an input impedance of 10 Mohms. The DC voltages are stated in volts (V), e.g. 0.7V. All oscillograms and AC voltages have been measured in relation to ground with an oscilloscope or a voltmeter with an input resistance of 1Mohm.
