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 the 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 your AirPrime SL8084T 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 SL8084T modem 

MUST BE POWERED 

OFF

. Otherwise, the SL8084T modem can transmit signals that could interfere with this 

equipment. 

 

In an aircraft, the SL8084T modem 

MUST BE POWERED OFF

. Otherwise, the SL8084T 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 a cellular phone in an 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 SL8084T modem may be used normally at this time. 

6.3. 

Important Compliance Information for North 
American Users 

The SL8084T modem has been granted modular approval for mobile applications. Integrators may 
use the SL8084T 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 20 cm 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 6 dBi in the cellular band and 3.5 dBi in the PCS band. 

3.

 

The SL8084T modem

 

and its antenna must not be co-located or operating in conjunction with 

any other transmitter or antenna within a host device.
