Multi-Tech Systems, Inc. SocketModem CDMA Developer’s Guide 16
General Safety Standards
THIS WIRELESS SOCKETMODEM COMPLIES WITH ALL APPLICABLE RF SAFETY STANDARDS.
This cellular modem meets the standards and recommendations for the protection of public exposure to
RF electromagnetic energy that have been established by governmental bodies and other qualified
organizations, such as the following:
• Directives of the European Community,
• Directorate General V in Matters of Radio Frequency Electromagnetic Energy
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 Multi-Tech SocketModem is a CDMA (PCS 800/1900) terminal which operates in the US
licensed PCS frequency spectrum. The device transmits over the 1850-1910 MHz or 824-849 MHz
bands and receives over the 1930-1990 MHz or 869-894 MHz bands. Multi-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 intended 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 20 cm is normally maintained between
the transmitter's antenna and the body of the user or nearby persons. The Modem is not designed for
or intended 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 20 cm 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 modem 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 Multi-Tech 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.
