8. Regulatory Information

8.1.

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.
8.2.

Safety and Hazards

Do not operate the AR7558 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.
8.3. 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 a mobile-only
exposure condition must not exceed the gain values presented in the table below:

4.5 dBi in Cellular band

1.0 dBi in PCS band

5.0 dBi in LTE Band 4

1.0 dBi in LTE Band 25

4.5 dBi in LTE Band 26
