The CN3100 Vehicle Modem is a ruggedized subscriber device. It is waterproof and made to handle
wide temperature ranges. While primarily designed for vehicle usage, the device may be used in fixed
locations, such as in parks or at outdoor events.
It enables any Internet-ready device to connect to the xMax network, either wirelessly using secure
WiFi links or through a wired Ethernet connection.
This manual provides basic instructions for installation and configuration of the CN3100 Vehicle
Modem. It also describes how to connect to the xMax Network and then connect Internet-enabled
wireless devices to the xMax Network.

The CN3100 Vehicle Modem Status LED indicates power, WiFi and network status and hardware fault
conditions.
Under normal operating conditions, the LED glows GREEN.
Be sure to read, understand and follow these instructions.
Heed all warnings.
Only use accessories and attachments specified by xG Technology.
Keep a copy of these instructions for future reference.
The CN3100 Vehicle Modem MUST only be installed by a professional installer. It is the responsibility
of the installer to adjust the transmit power level to ensure that the output power plus antenna gain
does not cause the device to exceed FCC Part 15 output power regulations.
All antennas MUST either be located on the exterior of a vehicle or mounted on a pole.
Every antenna MUST be separated from users by more than 25 cm (0.82 ft) at all times.
Shielded and grounded Ethernet cable MUST be used to avoid damage to the CN3100 Modem
unit and ensure proper operation.
Lightning Protection MUST be used on all antenna connections and Ethernet tower runs.
NOTE
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced radio technician for help.
Changes or modifications to this device not expressly approved
by xG Technology could void the user’s authority to operate
the equipment and void the product warranty.

DRAFT
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with minimum distance of 25 cm (0.82 ft) between
the radiator and your body. This transmitter MUST not be co-located or operating in conjunction with
any other antenna or transmitter.
The CN3100 has four antenna connectors — two Tx/Rx and two Rx-only.
All connectors are always used.
The WiFi antenna can be positioned in any convenient location.
On a vehicle, magnetic-mount or through-hole mount antennas may be used.
FOR OPTIMUM PERFORMANCE
The CN3100 should be placed as close as possible to the antennas.
The antenna cable lengths should be as short as possible.
Use of Low-loss cables (LMR 195/240 or equivalent) is highly recommended.
When using four antennas
The cables from the two Tx/Rx connectors on the CN3100
should be connected to the two antennas on one diagonal.
The cables from the two Rx connectors on the CN3100
should be connected to the two antennas on the opposite diagonal.
When using two dual-polarity antennas, connect the cables as shown:
