Communicating with Other Devices
Connect the external device to either of the USB ports on the back of the cradle, and then place
the GoBook II onto the vehicle cradle. You can install or remove the computer from the vehicle
cradle without connecting or disconnecting the cables.
Vehicle Mount Antennas
You can also connect an external RF antenna to the cradle using the SMA RF connector on the
back of the vehicle cradle. FCC regulations require that users of vehicle-mounted antennas must
use only antennas authorized for use with the GoBook II in order to meet FCC RF exposure
limits. Please contact your organization’s help desk for a list of approved vehicle-mounted
antennas. For mounting installation and/or mounting instructions for these types of antennas, see
the instructions that accompany each antenna.
RF Antenna Placement
WARNING Improper installation and/or operating configurations of permanent and magnetic
vehicle-mounted antennas may cause FCC RF exposure limits to be exceeded. Vehicle-mounted
antennas must be placed at least 20 cm from operators and bystanders.
Placement of a vehicle-mounted antenna
1. Measure and identify an area 20 cm (8 inches) in from the edges of the vehicle roof (see
diagram below).
2. Place the antenna within that area.
To maximize RF performance, position the antenna in the center of the vehicle roof.
Cleaning or Replacing Cradle Contact Pins
The contact pins on the vehicle cradle are exposed to contamination and stress when the computer
is installed and removed from the cradle during normal daily operation. If the pins become dirty,
they can be removed and cleaned as necessary using electrical contact cleaner. Or they can be
replaced. The power and ground pins are pins 3 and 8 respectively. When charging problems are
encountered and replacement pins are not available, other pins in the contact assembly can be used
to field fix the unit until replacement parts are available.
To clean or replace the cradle contact pins
1. Hold down the protective plastic cover.
