Explanation of diagram 2.2 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. AC voltages are stated in millivolts (mV), e.g. 660mV. ABO-CENTER v/HENRIKSENS ELEKTRONIK Caution The use of any controls, adjustments or procedures other than those specified herein may result in hazardous radiation exposure. CLASS 1 LASER PRODUCT COMPACT DIGITAL AUDIO The black and yellow label on the compact disc player serves as a warning that the apparatus contains a laser system and is classified as a class 1 laser product.
