Cautions

Electrostatic Discharge

CAUTION:
Electrostatic discharge (ESD) can damage circuit boards, disk drives, and other
components. Handle circuit board at an ESD workstation. If an approved station is not
available, wearing a grounded antistatic wrist strap provides some measure of
protection. Keep all plastic away from the board, and do not slide the board over any
surface.
After removing the board from its protective wrapper, place the board on a grounded,
static-free surface, component side up. Use an antistatic foam pad if available.
Ship and store the board inside a closed metallic antistatic envelope for protection.
Note:
The exterior coating on some metallic antistatic bags is sufficiently conductive to cause excessive
battery drain if the bag is in contact with the bottom side of the Tetra.

Handling Care

CAUTION:
Avoid touching the exposed circuitry with your fingers when handling the board. Though
it will not damage the circuitry, it is possible that small amounts of oil or perspiration on
the skin could have enough conductivity to cause the contents of CMOS RAM to
become corrupted through careless handling, resulting in CMOS resetting to factory
defaults.

Earth Ground Requirement

CAUTION:
All mounting standoffs for EPC boards should be connected to earth ground (chassis
ground). This provides proper grounding for EMI purposes.
