3.15. ENVIRONMENTAL ISSUES
Io200 Integrated Wireless Modems are designed for a combination of easy serviceability and general robustness. These integrated
modems are designed to be housed in an OEM host product. The modem is tested to conform to the environmental levels (for
example, industrial use specifications) that meet the intended applications of most integrators. If you need additional robustness
and safety in your products, you must engineer the environmental characteristics of your host product to achieve a special safety
rating.
3.16. General Precautions
Follow these precautions when working with wireless modems:
• Minimize the handling of static-sensitive modules and components.
• Wear a grounded anti-static wrist strap while handling static-sensitive components.
• Do not bend or stress the modem in any way.
• Reinsert connectors straightly and evenly to avoid causing short and open circuits.
3.17. ESD Handling Precautions
All electronic devices contain components that are sensitive to ESD (electrostatic discharge). For example, people typically
experience up to 35 kV ESD, while walking on a carpet in low humidity environments. In the same manner, many electronic
components can be damaged by less than 1000 V of ESD. For this reason, you must observe the following handling precautions
when servicing this equipment:
• Always wear a conductive wrist strap.
• Eliminate static generators (plastics, styrofoam, and so on) in the work area.
• Remove nylon or polyester jackets, roll up long sleeves, and remove or tie back loose hanging neckties, jewelry, and long
hair.
• Store and transport all static sensitive components in ESD-protective containers.
• Disconnect all power from the unit before ESD-sensitive components are removed or inserted, unless instructed otherwise.
• Use a static safe-guarded workstation, which can be set up by using an anti-static kit (Motorola part number 0180386A82).
This kit includes a wrist strap, two ground cords, a static control table mat, and a static control floor mat. The Motorola part
number for a replacement wrist strap that connects to the tablemat is 4280385A59.
When anti-static facilities are unavailable, use the following technique to minimize the chance of damaging the equipment:
• Rest the static-sensitive component on a conductive surface when you are not holding it.
• When setting down or picking up the static-sensitive component, make skin contact with a conductive work surface first and
maintain this contact while handling the component.
• If possible, maintain relative humidity of 70-75% in development labs and service shops.
