of the Subscriber Identification Module (SIM), this product does not contain consumerserviceable components.
2.0 Regulatory Compliance FCC
2.1 Integration Considerations and Installation Requirements
The Enabler II-G OEM GPRS 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.
•The modem was tested and certified to meet FCC Parts 15 and 24 in a stand-alone configuration,
which demonstrated that the Enabler II-G complies with Part 15 emission limits regardless of the
device into which it may be installed. Further, to provide relief in certain applications for the host
integrator, the Enabler II-G was approved under the "modular approval" process for a transmitter.
This approach, described by FCC Public Notice DA 00-131407 released June 26, 2000, is intended
to afford relief to equipment manufacturers by eliminating the requirement for obtaining a new
equipment authorization for the same transmitter when installed in a new device. However, the
host platform integrator must follow all installation instructions detailed in the Integration Guide and
as outlined in this section on Considerations and Requirements.
•In order to use the Enabler II-G without additional FCC certification approvals, the installation must
meet the following conditions:
•For the transmitter to meet the MPE categorical exclusion requirements of 2.1091, the ERP
must be less than 1.5 watts for personnel separation distance of at least 20 cm (7.9 in).
Therefore, the maximum antenna gain cannot exceed +3.3dBi. If greater than 1.5 watts exists,
then additional testing and FCC approval is required.
•If used in a "portable" application such as a handheld 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:
•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).

Version 1.00
•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
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1)

This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions: (1)

including interference that may cause undesired
•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.
•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.
The transmitter and antenna must not be collocated
other antenna or transmitter. Failure to observe
