CAUTION:

ESD (ElectroStatic Discharge) sensitive

device. Permanent damage may occur on

unconnected devices subject to high energy

electrostatic fields. Unused devices must be

stored in conductive foam or shunts.

Personnel should be properly grounded prior

to handling this device. The protective foam

should be discharged to the destination

socket before devices are removed.
