MAINTENANCE MTH800 TETRA Handportable Terminal / Basic Service Manual 6 - 5
To create a proper ground
• Ground the working surface of your service bench. If possible, use the
Motorola Static Protection Assembly (part #0180386A82) to ground your
service bench. This assembly contains a wrist strap, two ground cords, a table
mat, and a floor mat.
• Wear a conductive wrist strap in series with a 1Mg ohm resistor to ground.
• Do not wear nylon clothing when handling any printed-circuit board.
• Prior to touching any printed-circuit board, touch an electrical ground to
remove any static charge that might have accumulated.
To store or transport a circuit board
• Place the printed-circuit board in conductive, anti-static material.
• Do not insert the printed-circuit board into conventional plastic “snow” trays
used for transporting other devices.
