■Precautions

■■

(1)To check voltage, use digital Multimeter or an apparatus which input impedance of 10MΩ or greater.
(2)To check conductivity, use a circuit tester of 3V or less.
(3)Check mainly soldering at lead wires or electrical elements and switch operation, since elements (IC,

diode, transistor, resistor, or condenser) seldom cause the trouble.
(4)When checking, do not push elements or pull lead wires strongly.
(5)When checking voltage at patterns where switch operates, be careful not to prevent switch operation or

to scratch patterns.
(6)Before removing electrical parts, be sure to disconnect Power Supply.
(7)Before soldering, heat the soldering iron to 290 - 340℃. If higher, solder quickly.
(8)When handling ICs avoid static electricity.
