SAFETY CHECK-OUT
DZ230/DZ231:
After correcting the original service problem, perform the following
Power requirements
220 – 240 V AC, 50/60 Hz
safety check before releasing the set to the customer:
Power outputs (DIGITAL MEDIA PORT)
DC OUT: 5 V, 700 mA
HDZ235:
Power requirements
120 V AC, 60 Hz
Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.
Power consumption
On: 150 W Standby: 0.3 W (at the Power Saving mode)
LEAKAGE TEST The AC leakage from any exposed metal part to earth ground and

return to chassis, must not exceed 0.5 mA (500 microamperes.). Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
Design and specifications are subject to change without notice.
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 passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2 V AC range are suitable. (See
