Important Notice
Due to the nature of wireless communications, transmission and reception of data can
never be guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally
lost. Although significant delays or losses of data are rare when wireless devices are
used in a normal manner with a well-constructed network, the modem should not be
used in situations where failure to transmit or receive data could result in damage of any
kind to the user or any other party, including but not limited to personal injury, death, or
loss of property. Neither Sierra Wireless nor USRobotics accepts any responsibility for
damages of any kind resulting from delays or errors in data transmitted or received
using the modem, or for failure of the modem to transmit or receive such data.
Safety and Hazards
Do not operate the modem in areas where cellular modems are not advised without
proper device certifications. These areas include environments where cellular radio can
interfere such as explosive atmospheres, medical equipment, or any other equipment
which may be susceptible to any form of radio interference. The modem can transmit
signals that could interfere with this equipment. Do not operate the modem in any
aircraft, whether the aircraft is on the ground or in flight. In aircraft, the modem MUST
BE POWERED OFF. When operating, the modem can transmit signals that could
interfere with various onboard systems.
Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door is
open. Modems may be used at this time.
The driver or operator of any vehicle should not operate the modem while in control of a
vehicle. Doing so will detract from the driver or operator’s control and operation of that
vehicle. In some states and provinces, operating such communications devices while in
control of a vehicle may be an offence.

Overview
1. Overview
The USR3500 is a programmable modem bundled with our USRobotics Courier M2M
Open AT application. The USR3500 industrial grade USB and serial modem supports
penta-band 3G HSPA+ with dual antenna receive diversity and quad band 2G
GSM/GPRS/EDGE. It offers audio capabilities, GPS, digital I/O, and an expansion card
interface that accepts an Ethernet adaptor card (available separately).
The Courier M2M Open AT application is a robust software platform that enables the
modem to communicate with remote servers and hosts without the need of an intelligent
host controlling the modem. Key features include cellular module control, bearer
management, device management, GPS device control, and asset tracking
functionality.
The USR3500 is capable of integrating with many leading cloud application and
management services. Refer to http://www.usr.com/support/3500 for details.
For information regarding programming capabilities available through the Courier M2M
application, refer to the Courier M2M Application Guide at
http://www.usr.com/support/3500.
