Notes on chip component replacement

0 Never reuse a disconnected chip component.
0 Notice that the minus side of a tantalum capacitor may
be damaged by heat

Flexible Circuit Board Repairing

0 Keep the temperature of the soldering iron around
270°C during repairing.

0 Do not touch the soldering iron on the same conductor
of the circuit board (within 3 times).

0 Be careful not to apply force on the conductor when
soldering or unsoldering.

Operating Voltage

Before connecting the unit to the power source, check that
the operational voltage of your unit is the same as the local
power supply.

Where purchased Operating voltage
