CAUTION

Handle with Care

Use Anti-Static Precautions

NOTE: The ProPak II and PowerPak II enclosures incorporate circuitry to absorb most static discharges.

However, severe static shock may damage the unit. If the MiLLennium-GLONASS GPSCard is not in
a NovAtel-supplied enclosure, special handling precautions must be observed. Please see Appendix A,
Page 47, for details.
