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

21、g 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 m

22、etal 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 instrument

23、s. 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.

24、The 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、if 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 machi

DSP TEST MODE * It tests whether the DSP works correctly or not. When the DSP test is activated, the te

39、st 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 bro
