6. Regulatory Information
6.1. Important Notice
Because of 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 and its affiliates accept
no responsibility for damages of any kind resulting from delays or errors in data transmitted
or received using Sierra Wireless modem, or for failure of the Sierra Wireless modem to
transmit or receive such data.
6.2. Safety and Hazards
Do not operate the AR7552 modem:
 In areas where blasting is in progress
 Where explosive atmospheres may be present including refueling points, fuel
depots, and chemical plants
 Near medical equipment, life support equipment, or any equipment which may be
susceptible to any form of radio interference. In such areas, the AR Series device
MUST BE POWERED OFF. Otherwise, the AR Series device can transmit signals
that could interfere with this equipment
 In an aircraft, the AR Series device MUST BE POWERED OFF. Otherwise, the AR
Series device can transmit signals that could interfere with various onboard systems
and may be dangerous to the operation of the aircraft or disrupt the cellular network.
Use of cellular phone in aircraft is illegal in some jurisdictions. Failure to observe this
instruction may lead to suspension or denial of cellular telephone services to the
offender, or legal action or both.
 Some airlines may permit the use of cellular phones while the aircraft is on the
ground and the door is open. The AR Series device may be used normally at this
time.
6.3. Important Compliance Information for
USA OEM Integrators
The AR Series device is granted with a modular approval for mobile applications. Integrators
may use the AR Series device in their final products without additional FCC/IC (Industry
Canada) certification if they meet the following conditions. Otherwise, additional FCC/IC
approvals must be obtained.
1. At least 20cm separation distance between the antenna and the user’s body must
be maintained at all times.
2. To comply with FCC/IC regulations limiting both maximum RF output power and
human exposure to RF radiation, the maximum antenna gain including cable loss in
