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.
battery is virtually full.

If your battery is new or has not been used for several weeks, rely on the indicator light to
determine when the battery is fully charged. The gas gauge is unreliable in these cases; it
may read 100%, when the actual capacity is only 10%.
