TABLE OF CONTENTS SAFETY CHECK-OUT (US model only) After correcting the original service problem, perform the following

21、 safety checks before releasing the set to the customer: Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below. LEAKAGE The AC leakage from any exposed metal part to earth ground and from all exposed me

22、tal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microampers). Leakage current can be measured by any one of three methods. 1.A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers instructions to use these instruments

23、. 2.A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. 3.Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so analog meters must have an accurate low-voltage scale. T

24、he Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable.

35、f the power 1/u button is pressed again. ALL CLEAR mode; If the power 1/u button is pressed often the machine enters the DEMO mode, but before the demonstration starts, the display is turned off. Press 1/u again. No response is returned. The press 1/u again. The preset data is cleared and the machin

36、e enters the normal power-on state. SOUND FIELD CLEAR MODE * The preset sound field is cleared when this mode is activated. Use this mode before returning the product to clients upon completion of repair. * Procedure: While depressing the SOUND FIELD MODE button, press the power 1/u button to turn o

37、n the main power. The message S.F Initialize appears and initialization is performed. AM CHANNEL STEP 9 kHz/10 kHz SELECTION MODE (US,Canadian Model) * Either the 9 kHz step or 10 kHz step can be selected for the AM channel step. * Procedure: Set the FUNCTION to AM. Turn off the main power. While de

38、pressing the TUNING+ button or the PRESET TUNING + button, press the power 1/u button to turn on the main power. Either the message AM 9kHz Step or AM 10kHz Step appears. Select the desired step. DSP TEST MODE * It tests whether the DSP works correctly or not. When the DSP test is activated, the tes

39、t data is output from the DSP (IC1401: CXD2712R) of the DIGITAL board and is written in the RAM (IC1402: IDT71V016S). When the test data is read from the RAM by the DSP, the data output must be equivalent to the original data. If they disagree, an error is triggered. Errors can be caused by the brok

40、en data line or defective soldering. * Procedure While pressing the SETUP, LEVEL and SUR buttons, press the POWER button to enter the DSP test mode. The message DSP TEST MODE appears. When an error occurs, the message DSP2 ERROR is displayed. When there is no error, the message DSP2 NO ERROR appears

VERSION MODE * When this mode is used, the microprocessor version number is displayed. * Procedure: Press the POWER button while pressing the ENTER, LEVEL, and SUR buttons to

42、 turn on the power. The microprocessor version number appears as follows. SECTION 2 SERVICING NOTE 1. When the front panel is removed, the VR board is removed at the same time. Consequently the LEDs cannot be turned on and the sound volume cannot be increased or decreased from the remote control. 2.

43、 When servicing the DIGITAL board, be sure to connect the earth land of the DIGITAL board with the chassis frame so that the earth potential of the DIGITAL board must not be floated from the chassis frame.
