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
CAUTION! 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 Section15.203
(unique antenna connectors) and Section 15.247 (emissions).
CAUTION! 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: 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.
