Permanent dam- age may occur on unconnected devices sub- ject to high energy electrostatic fields. Un- used devices must be stored in conductive foam or shunts. Personnel should be prop- erly grounded prior to handling this device. The protective foam should be discharged to the destination socket before devices are re- moved. |
