Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is on the ground or in flight. In aircraft, the Sierra Wireless modem MUST BE POWERED OFF. When operating, the Sierra Wireless modem can transmit signals that could interfere with various onboard systems. Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door is open. Sierra Wireless modems may be used at this time. The driver or operator of any vehicle should not operate the Sierra Wireless modem while in control of a vehicle. Doing so will detract from the driver or operatorʹs control and operation of that vehicle. In some states and provinces, operating such ...

2: Power Interface Overview of operation Note: This chapter contains information for CDMA (MC57xx) and GSM (MC87xx) modules. Information that is unique to specific module types is clearly identified. The module is designed to use a 3.3V (nominal) power supply, provided by the host. It is the host’s responsibility to provide safe and continuous power to the module at all times; the module does NOT have an independent power supply, or protection circuits to guard against electrical issues. The module’s power state is controlled by the host’s assertion / de‐assertion of the signal. The module also W_Disable# monitors its supply voltage and requests shutdown if the supply is insufficient. Power signals The module must be connected to a 3.3V power supply (as ...
CDMA and GSM / UMTS Mini Card Hardware Integration Guide Note: ESD protection is highly recommended for the USIM connector at the point where the contacts are exposed, and for any other signals from the host interface that would be subjected to ESD by the user of the product.
• The USB interface is fully active. Low power mode In this state, RF (both Rx and Tx) is disabled in the module, but the USB interface is still active. This low power mode (ʺairplane modeʺ) is controlled by software commands through the host interface. For instructions on using the commands, refer to AT Command Set for User Equipment (UE) (Release 6) (+CFUN=0 command), AirCard595U/595/MC5725/MC5725V MiniCard CnS Reference (Document 2130754) (CNS_RADIO_POWER [0x1075] command), or MC87XX Modem CnS Reference (Document 2130602) (Disable Modem command). Usage models Usage models can be used to calculate expected current consumption. A sample usage model is provided in Table 2‐1.

CDMA and GSM / UMTS Mini Card Hardware Integration Guide Minimize RF cable losses to the antenna; the recommended • maximum cable loss for antenna cabling is 0.5 dB. Figure 3-1: Antenna connection points and mounting holes Ground connection When connecting the module to system ground: Prevent noise leakage by establishing a very good ground • connection to the module through the host connector. Connect to system ground using the two mounting holes at • the top of the module (as shown in Figure 3‐1). Minimize ground noise leakage into the RF. • Depending on the host board design, noise could potentially be coupled to the module from the host board. This is mainly an issue for host designs that have signals traveling along the length of the module, or circuitry operating at both ends of the module interconnects. Shielding The module is fully shielded to protect against EMI and to ensure compliance with FCC Part 15 ‐ “Radio Frequency Devices” (or equivalent regulations in other jurisdictions).

B: Regulatory Information Important notice Because of the nature of wireless communications, trans‐ mission 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. Safety and hazards Do not operate your MC57xx / MC87xx modem: • In areas where blasting is in progress Where explosive atmospheres may be present including • refuelling 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 MC57xx / MC87xx modem MUST BE POWERED OFF. Otherwise, the MC57xx / MC87xx modem can transmit signals that could interfere with this equipment. In an aircraft, the MC57xx / MC87xx modem MUST BE POWERED OFF. Otherwise, the MC57xx / MC87xx 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 ...
