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.
