2 Use of Active Subwoofer
2.1.Checking Player when Active Subwoofer is Used
1.This unit uses the active subwoofer to supply the power of the component, and the active subwoofer should be connected to the component to check operational conditions of the component.
2.2.Checking Main Unit Using Power Jig
If the active subwoofer is not available during time of repair to the unit, the following equipment could be used.
Jig product number
RFKZ0182 (110V , 127V, 220V, 230V - 240V for with voltage selector overseas domestic use).
5
SA-HT15EP / SA-HT15EG / SA-HT15EB
3 Before Repair and Adjustment (Using Active Subwoofer
Unit)
Disconnect AC power, discharge Power Supply Capacitors C546, C547, C548 & C549 through a 10 Ω, 1W resistor to ground. DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices.
After repairs are completed, restore power gradually using a variac, to avoid overcurrent. Current consumption at AC 120V, 60Hz in NO SIGNAL mode should be ~700 mA .
4 Safety Precautions
4.1.GENERAL GUIDELINES
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, make the following leakage current checks to prevent the customer from being exposed to shock hazards.
4.1.1.LEAKAGE CURRENT COLD CHECK
1.Unplug the AC cord and connect a jumper between the two prongs on the plug.
2.Measure the resistance value, with an ohmmeter, 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 1MΩ and 5.2Ω.
When the exposed metal does not have a return path to the chassis, the reading must be 
.
Fig. 1
4.1.2.LEAKAGE CURRENT HOT CHECK (See Figure 1.)
1.Plug the AC cord directly into the AC outlet. Do not use an isolation transformer for this check.
2.Connect a 1.5kΩ, 10 watts resistor, in parallel with a 0.15µF 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. In case a measurement is outside of the limits specified, there is a possibility of a shock hazard, and the equipment should be repaired and rechecked before it is returned to the customer.

5 Handling the Lead Solder
5.1.About lead free solder (PbF)
Distinction of PbF P.C.B. :
P.C.B.s (manufactured) using lead free solder will have a PbF stamp on the P.C.B.
Caution:
·Pb free solder has a higher melting point that standard solder; Typically the melting point is 50 - 70°F (30 - 40°C) higher. Please use a high temperature soldering iron. In case of the soldering iron with temperature control, please set it to 700 ± 20°F (370 ± 10°C).
·Pb free solder will tend to splash when heated too high (about 1100°F/600°C).
·When soldering or unsoldering, please completely remove all of the solder on the pins or solder area, and be sure to heat the soldering points with the Pb free solder until it melts enough.
6 About the Protection Circuitry
The protection circuitry may have operated if either of the following conditions is noticed: *No sound is heard when the power is supplied.
*Sound stops during a performance.
The functions of this circuitry is to prevent circuitry damage, for example, the positive and negative speaker connection wires are “shorted”, or if speaker systems with an impedance less than the indicated rated impedance of this unit are used.
If this occurs, follow the procedure outlined below:
1.Press the STANDBY 
/ON button, switch to STANDBY mode.
2.Determine the cause of the problem and correct it.
3.Press the STANDBY 
/ON button once again, supply the power.
Note:
When the protection circuitry functions, the unit will not operate unless the STANDBY 
/ON button is first switched STANDBY and then ON again.
