Electrostatic Discharge Sensitive (ESDS)

Device Handling

This unit contains ESDS devices. We recommend the following precautions when repairing,
replacing or transporting ESDS devices:

 Perform work at an electrically grounded work station.

 Wear wrist straps that connect to the station or heel straps that connect to conductive floor
mats.

 Avoid touching the leads or contacts of ESDS devices or PC boards even if properly
grounded. Handle boards by the edges only.

 Transport or store ESDS devices in ESD protective bags, bins, or totes. Do not insert
unprotected devices into materials such as plastic, polystyrene foam, clear plastic bags,
bubble wrap or plastic trays.
