    After correcting the original service problem, perform the fol-
lowing 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.

    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 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

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.
The Simpson 250 and Sanwa SH-63Trd are examples of a pas-
sive VOM that is suitable. Nearly all battery operated digital
multimeters that have a 2V AC range are suitable. (See Fig. A)

Procedure:
1. Set the FUNCTION of the receiver to the CD position and con-

firm that " [OPTICAL] " and "CD" appear on the display.

2. Insert the DTS test CD into the CD player and play the CD.

3. About three seconds later, confirm that the receiver recognizes

the optical signal and that the "DTS" and "dts [3/2]" are appear
on the display.  Confirm also that MULTI CHANNEL DECOD-
ING (blue lamp) flashes on the front panel.

 Be careful about an electrical shock caused by remains of electrical potential.

            The following parts on DC board have the +B or -B electrical potential.

Heat sink for rectifier diodes D801, 802
Aluminium case of smoothing capacitor C803, 804

           The 40-60V electrical voltage remains in C803, 804 when the power turns off.
           Be sure to discharge in the following manner before servicing.

           Discharging
              1. Pull out the power cord from the wall outlet.
              2. Connect 330 ohm 2W resistors between the heat
                  sinks for D801 and 802 and chassis individually.
              3. Check the electrical potential drops fully, then start
                  servicing.
