FCC Notices
PRELIMINARY DRAFT
IMPORTANT: The XLR PRO OEM RF Module has been certified by the FCC for use with
other products without any further certification (as per FCC section 2.1091). Modifications
not expressly approved by Digi International could void the user's authority to operate the
equipment.
IMPORTANT: The RF module has been certified for remote and base radio applications. If
the module will be used for portable applications, the device must undergo SAR testing.
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and
used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation.
If this equipment does cause harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures: Re-orient or relocate the
receiving antenna, Increase the separation between the equipment and receiver, Connect
equipment and receiver to outlets on different circuits, or Consult the dealer or an
experienced radio/TV technician for help.
FCC Limited Modular Approval
This is an RF module 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
programming 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 module are provided with operating instructions to
satisfy RF exposure requirements.
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 XLR PRO Approved Antennas on page 15. When integrated
into OEM products, fixed antennas require installation preventing end-users from
replacing them with non-approved antennas. Antennas not listed in the XLR PRO
Approved Antennas on page 15 must be tested to comply with FCC Section 15.203
(unique antenna connectors) and Section 15.247 (emissions).
12 XLR PRO Radio Frequency Module User Guide
IC (Industry Canada) Certification
PRELIMINARY DRAFT
WARNING: The FCC requires that all spread spectrum devices operating within the
Unlicensed radio frequency bands must limit themselves to a maximum radiated
power of 4 Watts EIRP. Failure to observe this limit is a violation of our warranty terms,
and shall void the user’s authority to operate the equipment. This can be stated as
follows:
RF power - cable loss + antenna gain <= 36 dBm eirp
Fixed Base Station and Mobile Applications
Digi RF Modules 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
If the module will be used at distances closer than 20cm to all persons, the device may be
required to undergo SAR testing. Co-location with other transmitting antennas closer than
20cm should be avoided.
RF Exposure
The following statement must be included as a CAUTION statement in OEM product
manuals.
CAUTION: This equipment is approved for mobile and base station
transmitting devices only. Antenna(s) used for this transmitter must be
installed to provide a separation distance of at least 20 cm from all persons
and must not be co-located or operating in conjunction with any other
antenna or transmitter.
IC (Industry Canada) Certification
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is
subject to the following two conditions: (1) this device may not cause interference, and (2)
this device must accept any interference, including interference that may cause undesired
operation of the device.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils
radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes: (1)
l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout
brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le
