RF Exposures
Pursuant to 47 CFR § 24.52 of the FCC Rules and Regulations, personal communications services (PCS)
equipment is subject to the radio frequency radiation exposure requirements specified in § 1.1307(b), § 2.1091
and § 2.1093 as appropriate.
The MultiTech ModemModule is a GSM (PCS 1900) terminal which operates in the US licensed PCS frequency
spectrum. The device transmits over the 1850-1910 MHz band and receives over the 1930-1990 MHz Band.
Mult-Tech Systems, Inc. certifies that it has determined that the Modem complies with the RF hazard
requirements applicable to broadband PCS equipment operating under the authority of 47 CFR Part 24, Subpart
E of the FCC Rules and Regulations. This determination is dependent upon installation, operation and use of the
equipment in accordance with all instructions provided.
The Modem is designed for and intends to be used in fixed and mobile applications. "Fixed" means that the
device is physically secured at one location and is not able to be easily moved to another location. "Mobile"
means that the device is designed to be used in other than fixed locations and generally in such a way that a
separation distance of at least 20cm is normally maintained between the transmitter's antenna and the body of
the user or nearby persons. The Modem is not designed for or intends to be used in portable applications (within
20 cm of the body of the user) and such uses are strictly prohibited. To ensure that the unit complies with current
FCC regulations limiting both maximum RF output power and human exposure to radio frequency radiation, a
separation distance of at least 20cm must be maintained between the unit's antenna and the body of the user
and any nearby persons at all times and in all applications and uses. Additionally, in mobile applications,
maximum antenna gain must not exceed 3 dBi (to comply with Section 24.232(b) and is limited to 7 dBi for fixed
applications. Finally, the tune-up procedure for the O9EM2113 ensures that the maximum RF output power of
the device does not exceed 30.0 dBm within the variations that can be expected due to quantity production and
testing on a statistical basis.
Instructions to OEMs
The MultiTech product manual includes specific warnings and cautions in order to ensure that OEMs are aware
of their responsibilities, with regards to RF exposure compliance, for products into which the modem is
integrated. With this guidance, the OEM will be able to incorporate into their documentation the necessary
operating conditions and warnings.
OEMs need to provide a manual with the ‘’final’’ product that clearly states the operating requirements and
conditions and that these must be observed to ensure compliance with current FCC RF exposure requirements /
MPE limits (see the “RF Exposures” section above). This will enable the OEM to generate (and provide the end-
user with) the appropriate operating instructions, warnings and cautions, and/or markings for their product.
