TABLE OF CONTENTS After correcting the original service problem, perform the following safety checks before releasing the set to the customer: Check the an

25、tenna 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 metal parts to any exposed metal part having a return to chassis, must

26、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. 2.A battery-operated AC milliammeter. The Data Precision 245 digita

27、l 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. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that

28、is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable.

When this test is activated, all segments turn on at the same time, then each segment turns on one after another. * Procedure: While depressing the FUNCTION MODE and the SOUND FIELD MODE buttons simu

36、ltaneously, press the power 1/u button to turn on the main power. All segments turn on at the same time, then each segment turns on one after another. When the CURSOR MODE button, B, V, v, or b is pressed, the indication advances in the following order: All segments on, Bridge 1, Bridge 2, All segme

37、nts off. FACTORY SET MODE * All preset contents are reset to the default setting. * Procedure: While depressing the FUNCTION MODE and the SOUND FIELD GENRE buttons simultaneously, press the power 1/u button to turn on the main power. The message FACTORY SET appears and the present contents are reset

38、 to the default values. ALL CLEAR MODE * All preset contents are 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 GENRE and the SOUND FIELD ON/OFF buttons simultaneously, press the powe

39、r 1/u button to turn on the main power. The message ALL CLEAR!appears and the preset data is cleared. 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

40、 the SOUND FIELD ON/OFF button, press the power 1/u button to turn on the main power. The message SURR CLEAR! appears and initialization is performed. AM CHANNEL STEP 9 kHz/10 kHz SELECTION MODE * Either the 9 kHz step or 10 kHz step can be selected for the AM channel step. * Procedure: Set the FUNC

41、TION to AM. Turn off the main power. While depressing 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 * Procedure: While depressing the FUNCTION MO

42、DE and the EQUALIZER buttons simultaneously, press the power 1/u button to turn on the main power. The message DSP NO ERROR or DSP ERROR. When DSP NO ERROR is displayed, a 1 kHz signal is output to all channels. When the B, V, v, or b button is pressed while DSP NO ERROR is displayed, the message DS

43、P TEST MODE appears. In this mode, the input signal that is selected by the FUNCTION key is distributed to each speaker. DTS MODE * Procedure: While depressing the B and b buttons simultaneously, press the power 1/u button to turn on the main power. The message ATTENUATE OFF or ATTENUATE ON. Speaker
