Safety and
Hazards
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.

Arduino-compatible Circuit
The mangOH Green includes an integrated Arduino-compatible circuit (with connector
for use with Arduino-compatible shields, and an Atmega32U4 microcontroller).
Figure 3-22: Integrated Arduino-compatible Circuit
The Arduino-compatible circuit is controlled directly via a mini-USB cable connection
from your computer. This connection is used to download sketches from your
computer using the Arduino IDE.
By default, the Arduino-compatible circuit’s UART is configured to connect to the
primary CF3 module‘s USB using an FTDI conversion chip (UART to USB). For
details, see Table 3-6 on page 33.
The Arduino-compatible circuit can also be accessed from the primary CF3 module,
