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 AirCard 400 modem are used in a normal manner with a well-constructed network, they should not be used in situations where failure to transmit or receive data could result in harm of any kind to the user or any other party, including but not limited to personal injury, death, or loss of property. Sierra Wireless, Inc., accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or received using the AirCard 400 modem, or for failure of the AirCard 400 modem to transmit or receive such data. Safety and Hazards Do not operate the AirCard modem 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 AirCard 400 modem MUST BE TURNED OFF. It can transmit signals that could interfere with this equipment. Do not operate the AirCard modem in any aircraft, whether the aircraft is on the ground or in flight. In aircraft, the AirCard modem MUST BE TURNED OFF. When operating, it can transmit signals that could interfere with various onboard systems. The driver or operator of any vehicle should not operate the AirCard modem while in control of a vehicle. Doing so will detract from the driver or operator's control and operation of that vehicle. In some jurisdictions, operating such communications devices while in control of a vehicle is an offence. WARNING - The FCC has developed guidelines to reduce any possible hazard due to exposure of the human body to electromagnetic radiation (i.e. to radio waves). In accordance with these guidelines, the antenna should be positioned at a distance greater than 4 cm (1.57") from users and bystanders — 2 cm (.79") from hands, wrists, feet, and ankles — when the modem is transmitting. Regulatory Information This device complies with Part 15 of the FCC Rules. Operation of this device is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operations. FCC ID: O6UACRD400 Where appropriate, the use of the equipment is subject to the following conditions: CAUTION - Unauthorized modifications or changes not expressly approved by Sierra Wireless, Inc. could void compliance with regulatory rules, and thereby your authority to use this equipment. WARNING (EMI) - United States FCC Information - This equipment has been tested and found to comply with the limits pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in an appropriate installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communication. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna l Increase the separation between the equipment and receiver l Connect the equipment into an outlet on a circuit different from that to which the receiver is connected l Consult the dealer or an experienced radio/TV technician for help l WARNING (EMI) - Canada - This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus as set out in the interference causing equipment standard entitled "Digital Apparatus", ICES-003 of the Department of Communications. Cet appareil numérique respecte les limites de bruits radioélectriques applicables aux appareils numériques de Classe B prescrites dans la norme sur le matériel brouilleur: "Appareils Numériques", NMB-003 édictée par le ministre des Communications. If you have purchased this product under a United States Government contract, it shall be subject to restrictions as set forth in subparagraph (c)(1)(ii) of Defense Federal Acquisitions Regulations (DFARs) Section 252.227-7013 for Department of Defense contracts, and as set forth in Federal Acquisitions Regulations (FARs) Section 52.227-19 for civilian agency contracts or any successor regulations.

FCC ID: O6UACRD400 PCMCIA Spread Spectrum Wireless Modem (FHSS) FCC Part 15 Certification Application (Amendment) Dear Mr. Dayhoff: On behalf of Sierra Wireless Inc. we hereby submit an amendment to the subject application in response to your request as follows: 1. For the body SAR measurements the EUT was positioned relative to the planar section of the phantom so that the area scan performed would measure any hot spot occurring in that region. However, the EUT was inadvertently positioned causing the center of the dipole antenna to be shifted from the center of the phantom. The EUT overlay is adjusted in order to correlate with the location of the hot spot (please see attached revised body SAR test plots). Please note that the actual SAR values determined are not affected by the EUT overlay. If you have any further questions or comments, please do not hesitate to contact the undersigned.

The modem will be sold or rented to subscribers of the Ricochet service. The Ricochet service allows subscribers to send / receive email, connect to the Internet, etc. without the necessity of a telephone line. The AirCard 400 modem is a frequency hopping spread spectrum radio-modem that operates within the 902-928 MHz band. The modem transmits and receives digital packet data. The transmit power of the modem is just below 1 Watt. The modems are capable of communicating with MCDN radios that make up the MCDN network or other modems. A technical overview of the MCDN network is contained in the included file “add_tech_info.pdf”. The AirCard 400 modem is capable of transmitting in two different modulations. “2FSK” - 2 “position” frequency shift keying “4FSK” - 4 “position” frequency shift keying These are referred to as MOD 1 and 2 respectively. The modulations are chosen automatically by the modem depending on the robustness of the communications link between itself and the Network Radio. Sierra Wireless, Inc.

These tests are typically performed on the following channels / frequencies: Channel Frequency ( MHz ) Low 902.16 Mid 914.16 High 924.08 These are referred to as the “Standard Test Channels”. Many of the tests required that the EUT be operated in modes that are not possible with the normal operating software, for example, the hopping function disabled. In these cases, some special instructions must be sent to the EUT. This is referred to operating the EUT in Diagnostic Mode. It is not possible for a typical AirCard 400 user to operate the modem in Diagnostic Mode. The tests below are performed using the basic test setup shown in Fig 1.
