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

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

Access
Thecommandsinthisreferenceareprotectedbypasswords.
Tousethesecommands,youmustenterthecorrectpassword
usingAT!ENTERCND(seepage27).Oncethepasswordis
entered,allcommandsareavailableandremainavailableuntil
themodemisresetorpoweredoffandon.

ThepasswordassignedtoAT!ENTERCNDisuniquetoeach
carrierandisconfiguredontothemodemduringmanufacture.
Ifyoudonotknowyourpassword,contactyourSierra
WirelessAccountManager.
Command timing
Somecommandsrequiretimetoprocessbeforeadditional
commandsareentered.Forexample,themodemwillreturn
“OK”whenitreceivesAT!DAFTMACT.IfAT!DASBANDis
receivedtoosoonafterthis,themodemwillreturnanerror.
Whenbuildingautomatedtestscripts,ensurethatsufficient
delaysareembeddedwherenecessarytoavoidtheseerrors.
