Important
Notice
Safety and
Hazards
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 such as the Sierra Wireless mobile hotspot are used in a normal manner
with a well-constructed network, the Sierra Wireless mobile hotspot 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. Sierra Wireless accepts no responsibility for
damages of any kind resulting from delays or errors in data transmitted or
received using the Sierra Wireless mobile hotspot, or for failure of the Sierra
Wireless mobile hotspot to transmit or receive such data.
Do not operate the Sierra Wireless mobile hotspot in areas where blasting is in
progress, where explosive atmospheres may be present, near medical
equipment, near life support equipment, or any equipment which may be
susceptible to any form of radio interference. In such areas, the Sierra Wireless
mobile hotspot MUST BE POWERED OFF. The Sierra Wireless mobile hotspot
can transmit signals that could interfere with this equipment.
Do not operate the Sierra Wireless mobile hotspot in any aircraft, whether the
aircraft is on the ground or in flight. In aircraft, the Sierra Wireless mobile hotspot
MUST BE POWERED OFF. When operating, the Sierra Wireless mobile hotspot
can transmit signals that could interfere with various onboard systems.
Limitation of
Liability
Note: Some airlines may permit the use of cellular phones while the aircraft is on the
ground and the door is open. Sierra Wireless mobile hotspots may be used at this time.
The driver or operator of any vehicle should not operate the Sierra Wireless
mobile hotspot 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 is an offence.
The information in this manual is subject to change without notice and does not
represent a commitment on the part of Sierra Wireless. SIERRA WIRELESS AND
ITS AFFILIATES SPECIFICALLY DISCLAIM LIABILITY FOR ANY AND ALL
DIRECT, INDIRECT, SPECIAL, GENERAL, INCIDENTAL, CONSEQUENTIAL,
PUNITIVE OR EXEMPLARY DAMAGES INCLUDING, BUT NOT LIMITED TO,

ADVISED OF THE POSSIBILITY OF SUCH DAMAGES OR THEY ARE
FORESEEABLE OR FOR CLAIMS BY ANY THIRD PARTY.
Notwithstanding the foregoing, in no event shall Sierra Wireless and/or its

6: Regulatory and Safety Information
Notice
Because of the nature of wireless communications, transmission and
reception of data can never be guaranteed. Data may be delayed,
corrupted (that is, have errors), or be totally lost. Although significant
delays or losses of data are rare when wireless devices such as the
Sierra Wireless mobile hotspot are used in a normal manner with a
well-constructed network, the Sierra Wireless mobile hotspot 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.
Sierra Wireless and its affiliates accept no responsibility for damages
of any kind resulting from delays or errors in data transmitted or
received using the Sierra Wireless mobile hotspot, or for failure of the
Sierra Wireless mobile hotspot to transmit or receive such data.
Safety and hazards
The mobile hotspot MUST BE POWERED OFF in all areas that may
be susceptible to radio interference, in particular:
• Prohibited areas
Obey all signs and notices and follow all rules and regulations.
Power off the mobile hotspot when instructed to do so or when
you suspect that it may cause interference or danger.
• In areas where blasting is in progress
• Where explosive atmospheres may be present
Areas with a potentially explosive atmosphere are not always
clearly marked. Such areas include gas stations, fuel depots,
chemical transfer or storage facilities, areas where blasting is in
progress, areas where the air contains chemicals or particles
such as grain, dust, or metal powders, and any other area where
you would normally be advised to turn off your cellular phone or
vehicle engine.
• Near medical or life-support equipment
Medical equipment may be susceptible to any form of radio interference. In such areas the mobile hotspot can transmit signals
that could interfere with this equipment.
• On board aircraft
In addition to Federal Aviation Authority (FAA) requirements,
many airline regulations state that you must suspend wireless
operations before boarding an aircraft. The mobile hotspot is
capable of transmitting signals that could interfere with various
onboard systems and controls.

Rev 2 Jun.11 33
Sierra Wireless AirCard 753S Mobile Wi-Fi User Guide
Failure to observe this instruction may lead to suspension or denial of cellular
telephone services to the offender, legal action, or both.
Some airlines may permit the use of cellular phones while the aircraft is on the
ground and the door is open. The mobile hotspot may be used normally at this
time.
• While operating a vehicle
The driver or operator of any vehicle should not use a wireless data device
while in control of a vehicle. Doing so detracts from the driver or operator's
ability to control and operate the vehicle. In some countries, using such communications devices while in control of a vehicle is an offence.
Proper Battery Use and Disposal
Note: Improper battery use may result in a fire, explosion, or other hazard.
To ensure safe and responsible battery use:
• Do not open, disassemble, puncture, crush, bend, or shred.
• Do not expose to water or other liquids, fire, explosion, or other hazards.
• Use the battery only in the Mobile Wi-Fi.
• If using with a charger, use only the charger supplied with the Mobile Wi-Fi.
• Do not short circuit the battery.
• When replacing a battery, use the same model of battery that was supplied
with the Mobile Wi-Fi.
• Follow local regulations when disposing of a used battery.
• Avoid dropping the Mobile Wi-Fi or the battery. If dropped and you suspect
damage, take it to a service center for inspection.
Caution: The Sierra Wireless Mobile Wi-Fi must be 1 cm or more from users during
operation, to satisfy the EMR requirements. If an external antenna is used, the antenna
must be maintained at least 20 cm from users during operation. To meet the EMR requirements, use only the external antennas available from Sierra Wireless.
