■ 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)Since this model uses lead-free solder, a soldering iron tip temperature of 280 - 350°C is sufficient.
But when it cannot melt solder, use a higher temperature for a short period of time.
Be sure to control soldering iron tips used for lead-free solder and those for leaded solder so they are
managed separately.
This is because mixing lead-free solder and leaded solder will cause detachment phenomenon.
(8)When handling ICs avoid static electricity.
Caution for Battery and Circuit board disposal
Always follow local regulations for disposal.
Tape over the lithium-ion battery contacts to avoid short-circuiting during disposal.
Caution for Product disposal
Do not dispose of this product together with your household waste.
Please refer to the information of your local community or contact our dealers regarding the proper
handling of end-of-life electric and electronic equipment.
Recycling of this product will help to conserve natural resources and prevent potential negative
consequences for the environment and human health caused by inappropriate waste handling.
