2 SRS-D313 SAFETY CHECK-OUT After correcting the original service problem, perform the following safety check 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 TEST 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 microamperes.). Leakage current can be measured by any one of three methods. 1. A commercial leakage tester, such as the Simpson 229 or RCAWT-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.

D Subwoofer Caisson de grave Tiefsttonlautsprecher Potenciación de graves Hooking up the system 1 Attach the reflector to the speakers. (See fig. A.) 2 (See fig. B for steps 2 through 4.)Connect the left speaker cord 8 pin plug to the rear panel jack with their respective arrows aligned. 3 Connect the subwoofer to the wall outlet. 4 Connect the CD walkman, PC, etc., to the INPUT jack on the left speaker. 5 Position the speakers. (See fig. C.) Listening to the sound (see fig. D) First, turn down the volume on the left speaker. The volume should be set to minimum before you begin playing the programme source. 1 Press POWER on the left speaker.The POWER indicator lights up green.
