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.
The black and yellow label on the compact disc player serves as a warning that the
apparatus contains a laser system and is classifi ed as a class 1 laser product. The
apparatus must be opened by qualifi ed servicemen only.
Wavelength 780 nm ±20 nm, 30ºC
Effect
2 mW ±0.1 mW, 30ºC
Short-circuit and overcharging of some types of lithium batteries may result in a
violent explosion.
When replacing the lithium battery in this set, note the following:
Use only batteries of the same make and type as mentioned in this service manual
(see page 3.9).
Place the battery exactly like the old one.
Replace with the same type 1 ampere 250 volts quick acting fuse.
Replace with the same type 2.5 ampere 250 volts slow acting fuse.
Remplacer par un fusible rapide de même type et de 1 ampères 250 volts.
Remplacer par un fusible retardè de même type et de 2.5 ampères 250 volts.
