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.
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.
Limitation of
Liability
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.

WAN connection if an appropriate SIM card is installed, and the APN
is configured correctly.
2
Note: Additional configuration is always recommended.
To start the MG90:
1. Apply power to the system:
· If the MG90 has been installed and wired into a vehicle's
electrical system, turn on the ignition.
· If the MG90 is not in a vehicle (for example, on a test bench),
use the optional AC power adapter.
The MG90 should fully power up within two minutes. When the
MG90 is turning on, the Power LED flashes green, then turns
solid green, and other LEDs begin to display their regular behavior. For more information on the LED patterns see LED Behavior
on page 26.
2. If the MG90 does not start automatically, press and release the
Reset button on the front panel.
3. Test the unit—Connect a test device (for example, a PC) to the
MG90 LAN via:
· Wi-Fi—An MG90 with factory default settings provides an
unsecured Vehicle Wi-Fi access point (AP) broadcasting its
own Serial Number as the SSID (e.g. ND60510068011018)
· Ethernet— Ethernet ports 1–4 (factory default configured for
LAN access)
Refer to the AirLink MG90 Software Configuration Guide for
configuration/ usage instructions.

corner for proper SIM card alignment.
If you are using only one SIM card for a radio module, Sierra Wireless recommends
that you install it in the module’s ‘1’ slot (e.g. SIM Card A1, SIM Card B1).
If the SIM card(s) are not already installed, insert them into the MG90 before
connecting any external equipment or power to the unit.
To install the SIM card(s):
1. Use a #1 Phillips screwdriver to remove the SIM card cover (2 screws).
Important: These are ‘captive’ screws that remain attached to the cover. Do NOT remove
them from the door.
2. Orient the SIM card(s), as shown in Figure 2-1 (Gold contacts on the SIM cards
face-up).
3. Gently slide the SIM cards into their slots until they click into place.
(To remove a SIM card, press the SIM card in until it clicks, and release it. Gently
grip the SIM card and pull it out.)
