Preface

Important Notice

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 wireless module are used in a normal
manner with a well-constructed network, the Sierra Wireless wireless module
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 wireless module, or for failure of
the Sierra Wireless wireless module to transmit or receive such data.

Do not operate the Sierra Wireless wireless module 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
wireless module MUST BE POWERED OFF. The Sierra Wireless wireless
module can transmit signals that could interfere with this equipment.

Do not operate the Sierra Wireless wireless module in any aircraft, whether the
aircraft is on the ground or in flight. In aircraft, the Sierra Wireless wireless
module MUST BE POWERED OFF. When operating, the Sierra Wireless wireless
module can transmit signals that could interfere with various onboard systems.

Limitation of Liability

Note: Some airlines may permit the use of cellular phones while the aircraft is on the
ground and the door is open. Sierra Wireless wireless modules may be used at this time.

The driver or operator of any vehicle should not operate the Sierra Wireless
wireless module 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.

The information in this manual is subject to change without notice and does not
represent a commitment on the part of Sierra Wireless. SIERRA WIRELESS AND
ITS AFFILIATES SPECIFICALLY DISCLAIM LIABILITY FOR ANY AND ALL
DIRECT, INDIRECT, SPECIAL, GENERAL, INCIDENTAL, CONSEQUENTIAL,
PUNITIVE OR EXEMPLARY DAMAGES INCLUDING, BUT NOT LIMITED TO,
LOSS OF PROFITS OR REVENUE OR ANTICIPATED PROFITS OR REVENUE
ARISING OUT OF THE USE OR INABILITY TO USE ANY SIERRA WIRELESS
PRODUCT, EVEN IF SIERRA WIRELESS AND/OR ITS AFFILIATES HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES OR THEY ARE
FORESEEABLE OR FOR CLAIMS BY ANY THIRD PARTY.

Notwithstanding the foregoing, in no event shall Sierra Wireless and/or its
affiliates aggregate liability arising under or in connection with the Sierra Wireless
product, regardless of the number of events, occurrences, or claims giving rise to
liability, be in excess of the price paid by the purchaser for the Sierra Wireless
product.

2: Power

Power supply

The host provides power to the EM8805 through multiple power and
ground pins. The host must provide safe and continuous power (via
battery or a regulated power supply) at all times; the module does not
have an independent power supply, or protection circuits to guard
against electrical issues.

For detailed pinout and voltage / current requirements of this module,
see the AirPrime EM8805 Product Technical Specification &
Customer Design Guidelines.

Module power states

The module has five power states, as described in Ta bl e 2-1.
