3 SAFETY CHECK-OUT (US MODEL) 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 microampers.). Leakage current can be measured by any one of three methods.. A commercial leakage tester, such as the Simpson 9 or RCA WT-540A. Follow the manufacturers instructions to use these instruments.. A battery-operated AC milliammeter. The Data Precision 45 digital multimeter is suitable for this job.. 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 lowvoltage scale. The Simpson 50 and Sanwa SH-6Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a V AC range are suitable. (See Fig. A) To Exposed Metal Parts on Set 0.5 µf.5 kω AC voltmeter (0.75 V) Earth Ground Fig. A. Using an AC voltmeter to check AC leakage. SAFETY-RELATED COMPONENT WARNING!!

6 Operations Using the Remote RM-AAP00 You can use the remote RM-AAP00 to operate the components in your system. Before you use your remote Inserting batteries into the remote Insert R6 (size-aa) batteries with the + and properly oriented in the battery compartment. When using the remote, point it at the remote sensor on the receiver. Tip Under normal conditions, the batteries should last for about 6 months. When the remote no longer operates the receiver, replace all batteries with new ones. Notes Do not leave the remote in an extremely hot or humid place. Do not use a new battery with an old one. Do not expose the remote sensor to direct sunlight or lighting apparatuses. Doing so may cause a malfunction. If you don t use the remote for an extended period of time, remove the batteries to avoid possible damage from battery leakage and corrosion.
