Limited Modular Approval
Power output is conducted at the antenna terminal and can be adjusted from 1 mill-watt to 1 Watt
at the OEM level. This is an RF modem approved for Limited Modular use operating as a mobile
transmitting device with respect to section 2.1091 and is limited to OEM installation for Mobile and
Fixed applications only. During final installation, end-users are prohibited from access to any pro-
gramming parameters. Professional installation adjustment is required for setting module power
and antenna gain to meet EIRP compliance for high gain antenna(s).
Final antenna installation and operating configurations of this transmitter including antenna gain
and cable loss must not exceed the EIRP of the configuration used for calculating MPE. Grantee
(Digi) must coordinate with OEM integrators to ensure the end-users and installers of products
operating with the modem are provided with operating instructions to satisfy RF exposure require-
ments.
The FCC grant is valid only when the device is sold to OEM integrators. Integrators are instructed
to ensure the end-user has no manual instructions to remove, adjust or install the device.
FCC-approved Antennas
WARNING: This device has been tested with Reverse Polarity SMA connectors with the
antennas listed in the tables of this section. When integrated into OEM products, fixed
antennas require installation preventing end-users from replacing them with non-
approved antennas. Antennas not listed in the tables must be tested to comply with FCC
Section 15.203 (unique antenna connectors) and Section 15.247 (emissions).
Fixed Base Station and Mobile Applications
Digi RF Modems are pre-FCC approved for use in fixed base station and mobile applications. When
the antenna is mounted at least 20cm (8") from nearby persons, the application is considered a
mobile application.
Portable Applications and SAR Testing
When the antenna is mounted closer than 20cm to nearby persons, then the application is consid-
ered "portable" and requires an additional test be performed on the final product. This test is
called Specific Absorption Rate (SAR) testing and measures the emissions from the modem and
how they affect the person.
RF Exposure
This statement must be included as a CAUTION statement in OEM product manuals.
WARNING: This equipment is approved only for mobile and base station transmitting
devices. Antenna(s) used for this transmitter must be installed to provide a separation
distance of at least 30 cm from all persons and must not be co-located or operating in
conjunction with any other antenna or transmitter.
NOTE: The separation distance indicated in the above is 30 cm, but any distance greater than or
equal to 23 cm can be used (per MPE evaluation).
