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.

1. A commercial leakage tester, such as the Simpson 229 or RCA WT-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 lowvoltage 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. (See Fig. A)

Operations Using the Remote RM-AAP001

You can use the remote RM-AAP001 to operate the components in your system.

Before you use your

Remote button description

remote

Inserting batteries into the remote

Insert R6 (size-AA) batteries with the + and – properly oriented in the battery compartment. When using the re m ote, point it at the remote sensor on the re ceiver.

Tip

Under normal conditions, the batteries should last for about 6 months. When the remote no long er ope r ates 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 cau se 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.

THIS NOTE IS COMMON FOR PRINTED WIRING BOARDS AND SCHEMATIC DIAGRAMS. (In addition to this, the necessary note is printed in each block.)

for schematic diagram:

• All capacitors are in µF unless otherwise noted. (p: pF) 50 WV or less are not indicated except for electrolytics and tantalums.

• All resistors are in Ω and 1/ specified.

• 2 : nonflammable resistor.

• 5 : fusible resistor.

• C : panel designation.

• A : B+ Line.

• B : B– Line.

•Voltage and waveforms are dc with respect to ground

•Voltages are taken with a VOM (Input impedance 10 MΩ).

•Waveforms are taken with a oscilloscope.

• Circled numbers refer to waveforms.

• Signal path.
