Explanation of the fuse symboles used in the set
Explanation des symboles de fusible utilisés dans l'appareil
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.
AC voltages are stated in millivolts (mV), e.g. 660mV.
The use of any controls, adjustments or procedures other than those specifi ed
herein may result in hazardous radiation exposure.
