The LIFEPAK 9 defibrillator/monitor uses multilayer PCBs which are not
easily repaired. They consist of alternate layers of conductive patterns and
insulating material bonded together and interconnected with plated-through
holes. The internal layers and connection points are quickly damaged by too
much heat, rendering the entire PCB useless. Therefore, it is recommended
that all multilayer PCBs be returned to Physio-Control for repair or
replacement.
Caution Possible PCB damage. Improper handing can easily damage the PCBs
beyond repair. Plated-through holes connecting the circuitry on two sides
of the PCB can be damaged by too much heat.
