Ñ 3 Ñ SAFETY CHECK-OUT After correcting the original service problem, perform the follow- ing safety checks before releasing the set to the customer: Check the antenna terminals, metal trim, ÒmetallizedÓ knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below. LEAKAGE 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). Leak- age 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 manufacturersÕ 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 ÒlimitÓ 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) Fig. A.

Please note that it should be dixed to mechanical center position when you moved and do not know origin position. L702 of PLL board Do not touch the L702 on the PLL Board because it is not needed to adjust. Connection and Test Disc Connection of this unit to a AC-3 Dolby surround equipment will realize outstanding sound playback. Check if the respective surround channel outputs are playing back normally by the following method. Jig : Discription Part No. AC-3 TEST LD J-2501-132-A Connected Equipment: AC-3 LD player (This unit is also compatible with the digital versatile disc player (DVD). The DVD must be checked with the LD player using all the circuits of this unit.) Connecting Method: AC-3 RF output terminal AC-3 RF input terminal AC-3 RF output terminal Coaxial digital connecting cable VMC-10G, etc. (Optional) AC-3 compatible LD playerUnit Checking Method: Play back a test disc of the LD player, and check if the contents recorded on the disc case (printed on the disc case) are played back normally.
