Note, a blown fuse will often indicate that there is either a problem with a connection to
the BBX or with BBX itself. Check all connections before replacing a fuse.
CAUTION
For continued protection against risk of fire and equipment damage, replace only with
the correct type and rating of fuse.
Please refer to the Technical Data section of this manual for details on the voltage and
current requirements of BBX.
5 Communications Device
The BBX can use a variety of communication devices. In radio systems, this will be an
external mobile radio with its accompanying antenna. If a data system such as GPRS,
iDEN, CDPD, etc. is being used, then the communications device will be a modem (which
may be internal in the BBX). The size and location of the communications device should
be taken into account during the installation process to ensure that there is enough space
to mount and install all components of the system in the vehicle.
6 Antenna Installation
Antenna location has an extremely significant impact on the performance of a wireless
modem. Mentor Engineering recommends using a roof top antenna installed in the center
of the vehicle roof for best coverage and to meet SAR/MPE radiation specifications (See
Following section: RF Radiation Specifications).
Antenna installation requirements vary between different antennas. Contact Mentor for
specific Antenna information for your application. The following Figure shows the
preferred location of a rooftop antenna.

6.1 General Antenna Guidelines
• Position the antenna as high as possible on the body of the vehicle.
