• This service manual contains technical information which will allow service personnel’s to understand and service this model.
• If the circuit is changed or modified, this information will be followed by supplement service manual to be filled with theoriginal

service manual.

1. The base for this model is SC-ZT1GN/GS-S, SU-ZT1GN/GS-S, SB-ZT1GN/GS-S. You can refer to the original service man-

1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or

damaged by the short circuit.

2. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly

installed.

3. After servicing, carry out the following for leakage current checks to prevent the customer from being exposed to shock haz-

ards.

1. Unplug the AC cord and connect a jumper between the two prongs on the plug.
2. Using an ohmmeter measure the resistance value, between the jumpered AC plug and each exposed metallic cabinet part on

the equipment such as screwheads, connectors, control shafts, etc. When the exposed metallic part has a return path to the
chassis, the reading should be between 1MW and 5.2MW. When the exposed metal does not have a return path to the chas-
sis, the reading must be 

.

1. Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check.
2. Connect a 1.5kW, 10 watts resistor, in parallel with a 0.15mF capacitors, between each exposed metallic part on the set and a

good earth ground such as a water pipe, as shown in Figure 1.

3. Use an AC voltmeter, with 1000 ohms/volt or more sensitivity, to measure the potential across the resistor.
4. Check each exposed metallic part, and measure the voltage at each point.
5. Reverse the AC plug in the AC outlet and repeat each of the above measurements.
6. The potential at any point should not exceed 0.75 volts RMS. A leakage current tester (Simpson Model 229 or equivalent)

may be used to make the hot checks, leakage current must not exceed 1/2 milliamp. should the measurement is outside of
the limits specified, there is a possibility of a shock hazard, and the equipment should be repaired and re-checked before it is
returned to the customer.
