Introduction
This chapter presents instructions for installing the CrossCheck CDPD
Mobile Unit in a vehicle.

Warning –
The CrossCheck CDPD and its antennas and accessories
should only be professionally installed by Trimble Authorized dealers.
Warning
– To meet FCC RF exposure requirements, the maximum gain
for externally mounted antennas (plus any cable losses) cannot be more
than 3 dBi.
Warning
– To meet FCC RF exposure requirements, all persons must be
at least 20 cm from the CDPD antenna when the transmitter is operating.
2.2
Installing the CrossCheck CDPD Mobile Unit
The CrossCheck CDPD Mobile Unit can be installed before or after
configuring its firmware. For example, you might want to configure all
of the units for a fleet of vehicles prior to installation.
Note – If you plan to install the CrossCheck CDPD receiver before
installing the EchoLDX Message Terminal, be sure to leave adequate
clearance to the Mobile Data Terminal port and other connectors.
Adequate clearance must exist to connect the MDT to the unit, and you
must be able to read the LED indicators if troubleshooting is required.
