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 such as the Sierra Wireless modem are used

in a normal manner with a well-constructed network, the Sierra Wireless 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. Sierra Wireless

accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or

received using the Sierra Wireless modem, or for failure of the Sierra Wireless modem to transmit or

receive such data.

Safety and Hazards

Do not operate the Sierra Wireless 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 Sierra Wireless modem can transmit signals that could interfere

with this equipment. Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is

on the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE POWERED OFF. When

operating, the Sierra Wireless 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. Sierra Wireless modems may be used at this time.

The driver or operator of any vehicle should not operate the Sierra Wireless 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.

Limitations of Liability

This manual is provided “as is”. Sierra Wireless makes no warranties of any kind, either expressed or

implied, including any implied warranties of merchantability, fitness for a particular purpose, or

noninfringement. The recipient of the manual shall endorse all risks arising from its use.

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, LOSS OF PROFITS OR REVENUE OR ANTICIPATED PROFITS OR

REVENUE ARISING OUT OF THE USE OR INABILITY TO USE ANY SIERRA WIRELESS

PRODUCT, EVEN IF SIERRA WIRELESS 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 Sierra Wireless and/or its affiliates aggregate liability

arising under or in connection with the Sierra Wireless 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

Sierra Wireless product.
