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
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modem
MUSTBEPOWEREDOFF.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operatorʹscontrolandoperation
ofthatvehicle.Insomestatesandprovinces,operatingsuch
communicationsdeviceswhileincontrolofavehicleisan
offence.

Note: Some standard 3GPP commands are NOT supported, or are
partially supported. These commands are identified in Supported
GSM / WCDMA AT Commands, page 15.
Note: When designing applications that use these AT commands, use
Watcher®(and other Sierra Wireless applications) as functionality
templates to ensure proper use of command groups. For questions or
concerns relating to command implementation, please contact your
Sierra Wireless account representative.
