SAFETY CHECK-OUT

After correcting the original service problem, perform the following

safety checks before releasing the set to the customer.

Check the area of your repair for unsoldered or poorly-soldered

connections. Check the entire board surface for solder splashes

and bridges.

Check the interboard wiring to ensure that no wires are

"pinched" or contact high-wattage resistors.

Look for unauthorized replacement parts, particularly

transistors, that were installed during a previous repair. Point

them out to the customer and recommend their replacement.

Look for parts which, though functioning, show obvious signs

of deterioration. Point them out to the customer and

recommend their replacement.

Check the line cord for cracks and abrasion.

Recommend the replacement of any such line cord to the

customer.

Check the B+ voltage to see it is at the values specified.

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 0.5mA (500 microampers).

Leakage current can be measured by any one of three methods.

A commercial leakage tester, such as the Simpson 229 or RCA

TW-540A. Follow the manufacturers' instructions to use these

instruments.

A battery-operated AC milliammeter. The Data Precision 245

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 0.75V, 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 2V AC range are suitable. (See

Fig. A)

Unleaded solder

Boards 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 MARK

Unleaded 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 flow) 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.
