Tuner AM (MW,LW) DUT Bandpass 250Hz-15kHz LF Voltmeter e.g. 7122 707 48001 e.g. PM2534 RF Generator e.g. PM5326 S/N and distortion meter Ri=50: e.g. Sound Technology ST1700B Frame aerial e.g. 7122 707 89001 To avoid atmospheric interference all AM-measurements have to be carried out in a Faraday´s cage. Use a bandpass filter (or at least a high pass filter with 250Hz) to eliminate hum (50Hz, 100Hz).

Careless handling during repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the mass of the set via a wrist wrap with resistance. Keep components and tools also at this potential. GB Safety regulations require that the set be restored to its original condition and that parts which are identical with those specified, be used Safety components are marked by the symbol Lead free ! . CLASS 1 LASER PRODUCT 2-1 INSTRUCTIONS ON CD PLAYABILITY Customer complaint "CD related problem" Set remains closed! check playability 1 playability ok ? N Y "fast" lens cleaning 3 For flap loaders (= access to CD drive possible) cleaning method 4 is recommended check playability playability ok ?

The problem was obviously caused by a scratched, dirty or copy-protected CD. In case problems remain, the customer is requested to contact the workshop directly. The lens cleaning (method 3) should be mentioned in the addendum sheet. The final wording in national language as well as the printing is under responsibility of the Regional Service Organizations. Before touching the lens it is advised to clean the surface of the lens by blowing clean air over it. This to avoid that little particles make scratches on the lens. Because the material of the lens is synthetic and coated with a special anti-reflectivity layer, cleaning must be done with a non-aggressive cleaning fluid. It is advised to use “Cleaning Solvent The actuator is a very precise mechanical component and may not be damaged in order to guarantee its full function. Clean the lens gently (don’t press too hard) with a soft and clean cotton bud moistened with the special lens cleaner. The direction of cleaning must be in the way as indicated in the picture below. 3-1 BLOCK DIAGRAM SA5888 DISC DR-28F OPTICAL PICKUP DVD-DSP SPHE8202TQ SPI SDROM 2M*16Bit*4Banks SD/MMC CORD ANT SD+USB-2.0V SD-2.5V USB-3.5V DISC IN/OUT/DET A/D SD/USD DET CF111LVD-138M RDS DECORD TDA7478 MCU STM8Audio BT MCS(MB0502) DPS286 TFT DRIVER 12C TOPPOLY 3.5" DIGITAL TFT GPS MODULE AM/FM TUNER MODUL KEY/RC A/D PWM EEPROM 24C02 USB PORT MOTO DRIVER FLASH 32M(bit) VOL/EQ Audio VIDEO SWITCH VIDEO AMP.
