User's Manual

When handling the LMU-3030’s™ main-board (i.e. sub assembly) by itself or in a partial housing
proper ESD precautions should be taken. The handler should be in an ESD safe area and be properly
grounded.
GPS Ceramic Patch Handling
When handling the sub assembly it may be natural to pick it up by sides and make contact with the
antenna boards. In an uncontrolled ESD environment contact with the center pin of ceramic patch
antenna can create a path for electrostatic discharge directly to the GPS Module. The GPS Module is
very sensitive to ESD and can be damaged and rendered non-functional at low levels of ESD.
One should avoid contact with the center pin of the patch during handling. The Factory will be placing
a protective layer of Kapton® tape over the patch element to eliminate this ESD path.
Packaging
Anytime the sub assembly is shipped and it is not fully packaged in its final housing it must be sealed
in an ESD safe bag.
Electrical Over-Stress (EOS)
The GPS receiver can be damaged if exposed to an RF level that exceeds its maximum input rating.
Such exposure can happen if a nearby source transmits an RF signal at sufficiently high level to cause
damage.
Storage and Shipping
One potential source of EOS is proximity of one LMU-3030™ GPS Antenna to another LMU-3030™
GSM Antenna. Should one of the units be in a transmit mode the potential exists for the other unit to
become damaged. Therefore any LMU-3030™ GPS Antenna should be kept at least four inches apart
from any active LMU-3030™ GSM Antenna or any other active high power RF transmitter with power
greater than 1 Watt.
3.1.2 Battery backup devices
Please properly dispose of the battery in any of the CalAmp products that utilize one, do not just throw
used batteries, replaced batteries, or units containing a back-up battery into the trash. Consult your
local waste management facility for proper disposal instructions.
