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.
Safety and Hazards
Do not operate you AR8550 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 AR8550 modem
MUST BE POWERED OFF . Otherwise, the AR8550 modem can transmit
signals that could interfere with this equipment
• In an aircraft, the AR8550 modem MUST BE POWERED OFF. Otherwise, the
AR8550 modem 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 AR8550 modem may be used normally at this
time.
Important Compliance Information for USA OEM
Integrators
The AR8550 modem is granted with a modular approval for mobile applications. Integrators
may use the AR8550 modem 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 a mobile-
only exposure condition must not exceed 5dBi for Cellular band and 3.7dBi for CDMA
PCS band.
3. The AR8550 modem and the antenna must not be co-located or operating in
conjunction with any other transmitter or antenna within a host device.
