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.
SAFETY CHECK-OUT After correcting the original service problem, perform the following safety check before releasing the set to the customer: Check the antenna terminals, metal trim, "metallized" knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below. LEAKAGE TEST The AC leakage from any exposed metal part to ear |
