The patterns described herein are single causes only but do not cover all possible
causes. Make a comprehensive study of multiple causes of trouble based on the preced-
ing single causes.
Herein mentioned are principally electrical causes of trouble, excluding mechanical
causes.
- The causes of trouble enclosed in a solid-line frame ([-__]) indicate the state in the
normal condition.
. The causes of trouble enclosed in a dotted-line frame ({__]) indicate the state in an

MiCautions on Trouble-Finding Work
1.
Use the digital tester (Type 2507) basically as a measuring instrument; any other mea-
suring instrument with an input impedance of 10MQ or more may be used.
Since the electric parts, such as ICs, diodes, resistors, condensers, etc., are considered
trouble-free, put an exphasis on defective soldering, switches, etc., as the causes of
trouble.
. When confirming defective soldering do not press the parts unnecessaily or pull the lead
wires forcibly.
The most suitable temperature of a soldering iron tip is 300~350°C at base plate A
and about 250°C at base plate B. If, however, said temperature be unobtainable, be sure
to finish soldering in a short time.
