The CBA850 is a 3G/4G/LTE Wireless WAN Bridge, which integrates seamlessly
with existing network infrastructure. The CBA850 can be deployed as a primary
WAN or as a backup WAN to the primary wired network for the branch SRX
Series Services Gateways.
The CBA850 is Power over Ethernet (PoE) enabled and provides a high-speed,
automatic secondary path to access and control the network at remote
locations when connectivity is lost or when the primary connection fails.
The following models of CBA850 are available:
• CBA850 (without an integrated modem)
• CBA850LPE-VZ (with an integrated Verizon modem)
• CBA850LP3-EU (with an integrated EU modem)

Regulatory and Safety Information
Read all operating instructions and the safety
information below and before using the CBA850
device to avoid injury.
FEDERAL COMMUNICATION COMMISSION
INTERFERENCE STATEMENT: 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 o and on, the user is encouraged to try
to correct the interference by one 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
dierent from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV
technician for help.
FCC CAUTION: Any changes or modifications
not expressly approved by the party responsible
for compliance could void the user’s authority to
operate this equipment.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.
FCC Radiation Exposure Statement: This
equipment complies with FCC radiation exposure
limits set forth for an uncontrolled environment.
This equipment should be installed and operated
with a minimum distance of 20 cm between the
radiator and your body.
To comply with FCC regulations limiting both
maximum RF output power and human exposure
to RF radiation, for the CBA850-LE the maximum
antenna gain must not exceed 8 dBi in the cellular
band, 3 dBi in the PCS band and 10 dBi in the LTE
band. For the CBA850-LP the maximum antenna
gain including cable loss must not exceed 7.5 dBi
in the cellular band, 3 dBi in the PCS band, 5.5 dBi
in LTE Band 4, and 9 dBi in LTE Band 17. For the
CBA850-W the maximum antenna gain must not
exceed 9.2 dBi in the 2.5 GHz band (2496-2690
MHz).
SAFETY AND HAZARDS: Under no circumstances
should the CBA850 device be used in any areas (a)
where blasting is in progress, (b) where explosive
atmospheres may be present, or (c) that are near
(i) medical or life support equipment, or (ii) any
equipment which may be susceptible to any form of
radio interference. In such areas, the CBA850 device
MUST BE POWERED OFF AT ALL TIMES (since
the device otherwise could transmit signals that
might interfere with such equipment). In addition,
under no circumstances should the CBA850 device
be used in any aircraft, regardless of whether the
aircraft is on the ground or in flight. In any aircraft,
the CBA750B device MUST BE POWERED OFF
AT ALL TIMES (since the device otherwise could
transmit signals that might interfere with various
onboard systems on such aircraft). Furthermore,
under no circumstances should the CBA850 device
be used by the driver or operator of any vehicle.
Such use of the device will detract from the driver’s
or operator’s control of that vehicle. In some
jurisdictions, use of the CBA850 device while driving
or operating a vehicle constitutes a civil and/or
criminal oense.
Due to the nature of wireless communications,
transmission and reception of data by the CBA850
device can never be guaranteed, and it is possible
that data communicated or transmitted wirelessly
may be delayed, corrupted (i.e., contain errors), or
totally lost. The CBA850 device is not intended
for, and CradlePoint recommends the device
not be used in, any critical applications where
failure to transmit or receive data could result in
property damage or loss or personal injury of any
kind (including death) to the user or to any other
party. CradlePoint expressly disclaims liability for
damages of any kind resulting from: (a) delays,
errors, or losses of any data transmitted or received
using the device; or (b) any failure of the device to
transmit or receive such data.
Warning: This product is only to be installed by
qualified personnel!
