Notes on chip component replacement • Never reuse a disconnected chip component. • Notice that the minus side of a tantalum capacitor may be damaged by heat. Flexible Circuit Board Repairing • Keep the temperature of the soldering iron around 270 ˚C during repairing. • Do not touch the soldering iron on the same conductor of the circuit board(within 3 times). • Be careful not to apply force on the conductor when soldering or unsoldering. CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
