Enfora Enabler III-G
Modem Integration Guide
1. Safety Precautions
1.1. Important Safety Information
The following information applies to the devices described in this manual. Always observe all standard and
accepted safety precautions and guidelines when handling any electrical device.
• Save this manual: it contains important safety information and operating instructions.
• Do not expose the Enfora Enabler III-G product to open flames.
• Ensure that liquids do not spill onto the devices.
• Do not attempt to disassemble the product: Doing so will void the warranty. With the
exception of the Subscriber Identification Module (SIM), this product does not contain
consumer-serviceable components.
2. Regulatory Compliance FCC
2.1. Integration Considerations and Installation Requirements
The Enabler III-G modem is designed for use in a variety of host units, "enabling" the host
platform to perform wireless data communications. However, there are certain criteria relative to
integrating the modem into a host platform such as a PC, laptop, handheld or PocketPC®, monitor
and control unit, etc. that must be considered to ensure continued compliance with FCC
compliance requirements.
• In order to use the Enabler III-G modem without additional FCC certification approvals, the
installation must meet the following conditions:
• Maximum RF output power and antenna gain to meet Maximum Permissible Exposure
Requirements: GSM850 mode: Power at antenna port is +32 dBm. The maximum gain
is 4.5 dBi(2.35 dBd). GSM1900 mode: Power at antenna port is 31.3 dBm. The
maximum gain is 2 dBi in order to meet the requirements of maximum 2 watts EIRP for
mobile transmitters.If RF power and/or antenna gain is desired, a separate FCC
certification is required.
• If used in a "portable" application such as a handheld or body worn device with the
antenna less than 20 cm (7.9 in.) from the human body when the device is operating,
then the integrator is responsible for passing additional "as installed" testing and the
device will require it’s own FCC ID:
• SAR (Specific Absorption Rate) testing, with results submitted to the FCC for
approval prior to selling the integrated unit. If unable to meet SAR requirements,
then the host unit must be restricted to "mobile" use (see below).
• Unintentional emissions, FCC Part 15; results do not have to be submitted to the
FCC unless requested, although the test provides substantiation for required labeling
(see below).
• ERP and EIRP measurements for FCC Parts 22 and 24, alternatively a full retest on
FCC Parts 22 and 24 can be performed
GSM0308PB001 1Version DRAFT – 2/9/2007

Enfora Enabler III-G
Modem Integration Guide
• If used in a "mobile" application where the antenna is normally separated at least 20 cm
(7.9 in) from the human body during device operation, then an appropriate warning label
must be placed on the host unit adjacent to the antenna. The label should contain a
statement such as the following:
WARNING
RF exposure. Keep at least 20 cm
(7.9 in) separation distance from
the antenna and the human body.
• Host unit user manuals and other documentation must also include appropriate caution
and warning statements and information.
• If the FCCID for the modem is not visible when installed in the host platform, then a
permanently attached or marked label must be displayed on the host unit referring to the
enclosed modem.
For example, the label should contain wording such as:
Contains GSM/GPRS modem transmitter module
FCC ID: MIVGSM0308
This device complies with Part 15 of the FCC Rules.
Operation 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
operation.
OR
Contains FCC ID: MIVGSM0308
This device complies with Part 15 of the FCC Rules.
Operation 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
operation.
• Any antenna used with the modem must be approved by the FCC or as a Class II
Permissive Change (including MPEL or SAR data as applicable). The "professional
installation" provision of FCC Part 15.203 does not apply.
GSM0308PB001 2Version DRAFT – 2/9/2007

Enfora Enabler III-G
Modem Integration Guide
• The transmitter and antenna must not be co-located or operating in conjunction with any
other antenna or transmitter. Violation of this would allow a user to plug another
transmitter in to the product and potentially create an RF exposure condition.
WARNING
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.
2.2. Disclaimer
The information and instructions contained within this publication comply with all FCC, GCF,
PTCRB, R&TTE, IMEI and other applicable codes that are in effect at the time of publication.
Enfora disclaims all responsibility for any act or omissions, or for breach of law, code or
regulation, including local or state codes, performed by a third party.
Enfora strongly recommends that all installations, hookups, transmissions, etc., be performed by
persons who are experienced in the fields of radio frequency technologies. Enfora acknowledges
that the installation, setup and transmission guidelines contained within this publication are
guidelines, and that each installation may have variables outside of the guidelines contained
herein. Said variables must be taken into consideration when installing or using the product, and
Enfora shall not be responsible for installations or transmissions that fall outside of the
parameters set forth in this publication.
Enfora shall not be liable for consequential or incidental damages, injury to any person or
property, anticipated or lost profits, loss of time, or other losses incurred by Customer or any third
party in connection with the installation of the Products or Customer's failure to comply with the
information and instructions contained herein.
The Enabler III-G platform is designed with features to
support a robust connection. There are instances
where the module performance is beyond the control
of the intended design. Integrated designs that require
24 by 7 operation must implement power control via an
external circuit or by implementing power management
as specified within this design guide.

4.7. General layout guidelines for Enfora GSM modules
To ensure lowest possible EMI emission, maximum thermal conduction and mechanical integrity, all
metal tabs on the GSM module shield must be soldered down on to a continuous ground plane. The
PCB trace that feeds the RF output port must be 50ohm characteristic impedance, coplanar, or
routed into internal layers to keep the top layer continuous around and underneath the device.
Provide ample ground vias around metal tabs, the RF trace and launch pad. If possible, keep I/O and
power traces away from the RF port.
