NOTES ON CHIP COMPONENT REPLACEMENT Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be dam-

aged by heat.

SAFETY CHECK-OUTAfter correcting the original service problem, perform the follow-ing 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 TESTThe 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 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 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. (See Fig. A)

SECTION 1SERVICING NOTES

UNLEADED SOLDERBoards requiring use of unleaded solder are printed with the lead-free mark (LF) indicating the solder contains no lead.(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size)

: LEAD FREE MARKUnleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40 C higher

than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be

applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to

about 350 C.Caution: The printed pattern (copper foil) may peel away if

the heated tip is applied for too long, so be careful! Strong viscosity Unleaded solder is more viscous (sticky, less prone to fl ow)

than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc.

Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may

also be added to ordinary solder.

NOTE OF PERFORMING THE OPERATION CHECK IN THE STATE THAT HEAT SINK WAS REMOVEDWhen performing the operation check in the state that this unit was disassembled, it is possible to perform the operation check in the state that heat sink was removed. But dont perform the operation check in the long time, and perform the operation check in the volume state as low as possible.

CAPACITOR ELECTRICAL DISCHARGE PROCESSING When checking the board, for the electric shock prevention, con-nect the resistors to both ends of respective capacitors to discharge the capacitor.Note 1: When the connector that connects the POWER board to the MAIN

board is disconnected before discharging, completely fi nish dis-charging both boards, and then reconnect the connector. If dis-charging is not complete, sparking may occur when connecting the connector and cause a blown fuse.

Note 2: Be sure to discharge using a resistor of 800 or higher. (Do not discharge with a 0 resistor) Discharging at a location where excessive electric current fl ows

through a fuse may cause the fuse to blow.
