Preface
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 NETGEAR® modem are used in a normal manner with a well-constructed network,
the NETGEAR 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. NETGEAR accepts no
responsibility for damages of any kind resulting from delays or errors in data
transmitted or received using the NETGEAR modem, or for failure of the NETGEAR
modem to transmit or receive such data.
Do not operate the NETGEAR modem 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 NETGEAR modem MUST BE POWERED OFF. The
NETGEAR modem can transmit signals that could interfere with this equipment.
Do not operate the NETGEAR modem in any aircraft, whether the aircraft is on the
ground or in flight. In aircraft, the NETGEAR modem MUST BE POWERED OFF.. When
operating, the NETGEAR modem can transmit signals that could interfere with various
onboard systems.
The driver or operator of any vehicle should not operate the NETGEAR 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 is an offence.
Limitation of

represent a commitment on the part of NETGEAR. NETGEAR 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, LOSS OF PROFITS OR REVENUE OR ANTICIPATED
PROFITS OR REVENUE ARISING OUT OF THE USE OR INABILITY TO USE ANY NETGEAR
PRODUCT, EVEN IF NETGEAR AND/OR ITS AFFILIATES HAS BEEN 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 NETGEAR and/or its affiliates
aggregate liability arising under or in connection with the NETGEAR product, regardless
of the number of events, occurrences, or claims giving rise to liability, be in excess of
the price paid by the purchaser for the NETGEAR product.

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
AirCard 781S Mobile Hotspot are used in a normal manner with a wellconstructed network, the AirCard 781S 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. NETGEAR and its
affiliates accept no responsibility for damages of any kind resulting from
delays or errors in data transmitted or received using the AirCard 781S
Mobile Hotspot, or for failure of the AirCard 781S 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.

AirCard 781S Mobile Hotspot 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.
Caution: Unauthorized modifications or changes not expressly approved by NETGEAR, Inc. could
void compliance with regulatory rules, and thereby your authority to use this device.
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 hotspot.
• If using with a charger, use only the charger supplied with the mobile hotspot.
• Do not short circuit the battery.
• When replacing a battery, use the same model of battery that was supplied with
the mobile hotspot.
• Follow local regulations when disposing of a used battery.
• Avoid dropping the mobile hotspot or the battery. If dropped and you suspect
damage, take it to a service center for inspection.
