Protection of Static-Sensitive Devices
This unit contains static-sensitive devices. Static-sensitive devices must be protected in the following
conditions:
• When you are opening the unit.
• When storing any printed circuit board.
• When transporting any printed circuit board.
Create a Proper Ground
• Ground the working surface of your service bench. If possible, use the Motorola Solutions Static
Protection Assembly (Part Number: 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 1M ohm resistor to ground.
• Do not wear nylon clothing when handling any printed-circuit board.
• Before touching any printed-circuit board, touch an electrical ground to remove any static charge
that might have accumulated.
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.
