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 unpro-

tected devices into materials such as plastic, polystyrene foam, clear plastic bags, bubble

wrap or plastic trays.
