Conformance Notices

This section contains conformance notices.

Federal Communications Commission Notice

The Versatile/AB926EJ-S, Versatile/AB-IB1, and Versatile/IB-2 are test equipment and consequently are exempt from part 15 of the FCC Rules under section 15.103 (c).

The Versatile/AB-IB2 contains an Enfora Enabler II-G GSM Radio Module (FCC ID: MIVGSM0108). The GSM module complies with Part 15 of the FCC Rules for equipment intended for use in a commercial, industrial, or business environment. Use of the GSM module present on the Versatile/AB-IB2 is subject to the following conditions:

  • This GSM module must not cause harmful interference.

  • This GSM module must accept any interference received, including interference that may cause undesired operation.

  • The Versatile/AB926EJ-S and the Versatile/AB-IB2 must be used as a mobile or fixed device as defined under FCC regulations. Do not operate the Versatile/AB926EJ-S and the Versatile/AB-IB2 as a portable device. Use of the device on a desktop or other applications where the antenna can easily be relocated are considered by the FCC to be mobile applications.

  • Antenna gain for the GSM module output is limited to 3dBi. Modifications and/or additions to the Enfora Enabler II-G GSM transceiver, including use of antennas with higher than 3dBi gain, are prohibited. Mobile devices are limited to 2W EIRP under Part 24.

    The nominal RF output power of the GSM transceiver is 1.0W. The antenna supplied with the Versatile/AB-IB2 has a gain of 0dBi. The requirement for less than 2W EIRP will therefore be met if there are no modifications to the transceiver or antenna.

Enfora certifies that its Enfora Enabler II-G GSM Radio Module complies with the RF hazard requirements applicable to broadband PCS equipment operating under the authority of 47 CPR Part 24, Subpart E of the FCC Rules and Regulations. This certification is contingent upon installation, operation, and use of the Enfora Enabler II-G GSM Module in accordance with all instructions provided to the OEM and the end user. When installed and operated in a manner consistent with the instructions provided, the Enfora Enabler II-G meets the maximum permissible exposure (MPE) limits for general population/uncontrolled exposure as defined in Section 1.1310 of the FCC Rules and Regulations.

Warning

The AB-IB2 GSM module emits RF radiation. Keep at least 20cm (7.9in) separation distance from the antenna and the human body.

Follow all safety instructions in this manual, any warning notices on the product, and any applicable legal requirements and safety regulations (see also GSM module and the Enfora Enabler IIG GSM/GPRS Radio Modem Integration Guide GSM0108-01 at the Enfora website at www.enfora.com.)

The transmitter and antenna must not be collocated or operating in conjunction with any other antenna or transmitter. Failure to observe this warning could produce an RF exposure condition.

CE Declaration of Conformity

The system should be powered down when not in use.

The board generates, uses, and can radiate radio frequency energy and may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment causes harmful interference to radio or television reception, which can be determined by turning the equipment off or on, you are encouraged to try to correct the interference by one or more of the following measures:

  • ensure attached cables do not lie across the card

  • reorient the receiving antenna

  • increase the distance between the equipment and the receiver

  • connect the equipment into an outlet on a circuit different from that to which the receiver is connected

  • consult the dealer or an experienced radio/TV technician for help

Note

It is recommended that wherever possible Shielded interface cables be used.
