Reason: The switching contact provides the voltage for both the CD servo system and the audio power amplifier. Cure: Connect the emitter of Q 201 directly to the voltage supply. The switch is only used for controlling the base current which is much lower than the emitter current.

Reason: 1. When applying too much pressure when closing the cassette compartment door, the door may get jammed at the lower edge of the cabinet front below the display window. 2. Due to the tolerable differences in the length of the Play button lever it may happen that the lever slips out of its guide thus blocking the eject mechanism. All other functions work correctly. Cure: To 1: Modification of the cabinet front. To 2: Lengthened Play button lever by putting a metal clip on it. Introduction in the factory: 1 and 2: at the end of August/99 Workshop: To 1: Replace the cabinet front if necessary. To 2: 1. Open the cabinet on the back. 2. Undo the screws of the tape deck. 3. Take the tape deck out. 4. Put the metal clip on the Play button lever. 5. Re-assemble the receiver.

Reason: The above mentioned types of car radios switch the output stages off automatically when reaching a certain temperature threshold to avoid thermal damage. The period of time after which the output stages are switched off depends mainly on the volume setting and the temperature within the car. As soon as the car radio has cooled down, e.g. by reducing the volume level, the rear channels are automatically switched on again. Cure: Since this behaviour of the radios is not a fault but a built-in safety function, we would ask you to inform your customers accordingly when complaints are received. Workshop: Please note when complaints are received.

This is especially critical because the modules of both versions fit mechanically into each other. When replacing modules take care to use only the appropriate modules for the version.

Satellite Retrofit Kit SER 150 ET for chassis CUC 1805, 1825, 1826, 1827 (Digi Basic), 1806, 1828, 1829, 1830, 1836 (Digi Basic+), 1929, 1952, 1983, 1984, 1894 and 1842 (Digi 6) From now on, the SER 150 ET Retrofit Kit will be delivered without the EPROMs previously enclosed with the delivery for TV sets with Digi 6 and Digi Basic TV chassis. The TV sets have already been provided with a software covering all the functions of the SER 150 ET since 4/97. As a result, the EPROM of the currently delivered TV sets needs not to be exchanged. Should you receive a TV set manufactured before 1997 for retrofitting, check the software version (call up the version pressing the buttons i“ - OK“ - AUX“). If the version for the chassis: CUC 1805, 1825, 1826 and 1827 (Digi Basic) is lower than 19798-300.20, and for the chassis Digi 6 CUC 1842, 1894, 1984, 1952 and 1983 is lower than 19798-311.20, the EPROM needs to be replaced. The EPROM of TV sets with Digi Basic+ needs not to be replaced. The required IC is available from the Central After-Sales Service under part number 19798 300 2400 (Digi Basic) or 19798 311 4700 (Digi 6). 2 mm Serial No. 4/99 Service Information S1/4126900000 (8002/8012, 8005/8015) Central After-Sales Service TV 1/1 1.Colour television sets with chassis CUC 7303 and 45 cm Samsung or 51 cm Samsung/Videocolor picture tubes - e.g. P 45-830 text, P 45-847 FR/text, T 51-720 text, T 51-731 text, T 51-071, T 51-732/4 text, T 51-732/5 text Possible complaint: No operation - failure of the switched mode power supply (transistor / drive-IC / other components). Cause: Due to tolerances of the mains transformer 29201 513 9700 the collector current of transistor T 665 (MJF 1800) may reach limit values and consequently cause the power supply to fail. Cure: On replacement of the defective components change additionally the resistor R 666 from 0.82 Ohm to 0.91 Ohm. As a result limitation of the collector current is activated earlier so that the limit values will not be exceeded. Workshop: Carry out this change when the powe
