External Antennas
An external RF antenna also can be connected to the cradle using the SMA 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 MAX in order to meet FCC RF exposure limits. Please contact your
organizations’ 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 the Cradle Contact Connector
The contact connector on the vehicle cradle is exposed to contamination and stress when the computer is
installed and removed from the cradle during normal operation. If the contact connector becomes dirty,
it can be cleaned as necessary using electrical contact cleaner. 
To clean the cradle contact connector:
1. Remove the computer from the cradle
2. Ensure the cradle handle is in the "Open" position so that power will not be applied to the contact
connector during cleaning. 
3. Spray the blades and perimeter of the contact connector using Electrical Contact Cleaner
4. Allow any remaining electrical contact cleaner to evaporate prior to putting the computer back
onto the cradle and closing the handle.
CAUTION

Do not place any metal objects on top of the cradle that might make contact with the metal
