1-6. Lead-free Solder
All boards mounted in this unit use lead-free solder. Be sure to use lead-free solder when repairing the
boards of this unit. A lead free mark (LF) indicating that the solder contains no lead is printed on each
board.
(Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular
size.)
: LEAD FREE MARK
n
. The lead-free solder melts at a temperature about 40 dC higher than the ordinary solder, therefore, it is
recommended to use the soldering iron having a temperature regulator.
. The ordinary soldering iron can be used but the iron tip has to be applied to the solder joint for a slightly
longer time. The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so
be careful.

SAFETY CHECK-OUT
After correcting the original service problem,
perform the following safety checks before
releasing the set to the customer :
Check the 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 3.5 mA. 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 5.25 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 20 V AC
range are suitable. (See Fig. A)
