SCMB100-T Configured to use the on-board inverted-F trace antenna SCMB100-E Configured to use an external antenna attached via the u.fl connector Radio Operation The SCMB100 module has been certified using the GFSK modulation scheme employed by Bluetooth Low Energy devices. The transmitter may use both 1Mbit/s and 2Mbit/s modulation rates. The transmitter is not subject to any duty cycle restrictions. The output power from the transmitter must be limited (via software) to -4dBm to remain in compliance with FCC and IC regulations. The RF power amplifier may be enabled or disabled based on the users application. This device is approved to work with either 1) the on-board inverted-F PCB trace antenna or, 2) an external isolated magnet dipole antenna having a maximum gain of 2.5dBi. Regulator Notices Changes or modifications could void the users authority to operate the equipment. Federal Communications Commission The SCMB100 module complies with Part 15 of the FCC rules and regulations. Compliance with the labeling requirements, FCC notices and antenna usage guidelines is required. To fulfill FCC Certification, the OEM must comply with the following regulations:

1. The system integrator must ensure that the text detailed in OEM labeling requirements is placed on the outside of the final product. 2. This device may only be used with antennas that have been tested and approved for use with the module. OEM labeling requirements 2020 SmartSense by Digi. All Rights Reserved. Page 6 SCMB100 User Manual Rev 1.2 PRIVATE AND CONFIDENTIAL WARNING! As an Original Equipment Manufacturer (OEM) you must ensure that FCC labeling requirements are met. You must include a clearly visible label on the outside of the final product enclosure that displays the following content:

Contains FCC ID: 2ATZ3-SCMB100 This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1.) this device may not cause harmful interference and (2.) this device must accept any interference received, including interference that may cause undesired operation. FCC notices IMPORTANT: This module 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 SmartSense by Digi could void the user's authority to operate the equipment. IMPORTANT: OEMs must test final product to comply with unintentional radiators (FCC section 15.107 &

15.109) before declaring compliance of their final product to Part 15 of the FCC Rules. IMPORTANT: This 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 approved antennas This module can be installed using antennas and cables constructed with non-standard connectors

(RPSMA, RPTNC, etc.) An adapter cable may be necessary to attach the module connector to the antenna connector. The modules are FCC approved for fixed base station and mobile applications for the channels indicated in the tables below. If the antenna is mounted at least 20 cm (7.87 in) from nearby persons, the application is considered a mobile application. Antennas not listed in the table must be tested to comply with FCC Section 15.203 (Unique Antenna Connectors) and Section 15.247 (Emissions). The antennas listed below have been approved for use with this module:

Page 7 SCMB100 User Manual Rev 1.2 PRIVATE AND CONFIDENTIAL on-board inverted-F PCB trace antenna external isolated magnet dipole antenna having a maximum gain of 2.5dBi Contact SmartSense by Digi for additional details regarding applicable antennas. If using the RF module in a portable application (for example, if the module is used in a handheld device and the antenna is less than 20 cm from the human body when the device is in operation), The integrator is responsible for passing additional Specific Absorption Rate (SAR) testing based on FCC rules 2.1091 and FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields, OET Bulletin and Supplement C. The testing results will be submitted to the FCC for approval prior to selling the integrated unit. The required SAR testing measures emissions from the module and how they affect the person. RF exposure If you are an integrating the SCMB100 into another product, you must include the following Caution statement in OEM product manuals to alert users of FCC RF exposure compliance:

CAUTION! To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 20 cm or more must be maintained between the antenna of this device and persons during device operation. To ensure compliance, operations at closer than this distance are prohibited. The antenna used for this transmitter must not be colocated in conjunction with any other antenna or transmitter except the colocation(s) as allowed by the Grant Conditions of this module (FCC ID: 2ATZ3-

SCMB100). FCC publication 996369 related information In Publication 996369 section D03, the FCC requires information concerning a module to be presented by OEM manufacturers. This section assists in answering or fulfilling these requirements. 2.1 General No requirements are associated with this section. 2.2 List of applicable FCC rules This module conforms to FCC Part 15.247. 2.3 Summarize the specific operational use conditions Certain approved antennas require attenuation for operation. Host product user guides must include the antenna table if end customers are permitted to select antennas. 2020 SmartSense by Digi. All Rights Reserved. Page 8 SCMB100 User Manual Rev 1.2 PRIVATE AND CONFIDENTIAL 2.4 Limited module procedures Not applicable. 2.5 Trace antenna designs While it is possible to build a trace antenna into the host PCB, this requires at least a Class II permissive change to the FCC grant which includes significant extra testing and cost. If an embedded trace antenna is desired, simply select the SCMB100 module variant with the preferred antenna. 2.6 RF exposure considerations For RF exposure considerations see RF exposure and FCC-approved antennas (2.4 GHz). Host product manufacturers need to provide end-users a copy of the RF Exposure section of the manual: RF exposure. 2.7 Antennas A list of approved antennas is provided. 2.8 Label and compliance information Host product manufacturers need to follow the sticker guidelines outlined in OEM labeling requirements. 2.9 Information on test modes and additional testing requirements Contact a SmartSense sales representative for information on how to configure test modes for the SCMB100 product. 2.10 Additional testing, Part 15 Subpart B disclaimer All final host products must be tested to be compliant to FCC Part 15 Subpart B standards. While the SCMB100 unit was tested to be compliant to FCC unintentional radiator standards, FCC Part 15 Subpart B compliance testing is still required for the final host product. This testing is required for all end products, and SCMB100 Part 15 Subpart B compliance does not affirm the end products compliance. See FCC notices for more details. ISED (Innovation, Science and Economic Development Canada) Labeling requirements The integrator is responsible for its product to comply with IC ICES-003 & FCC Part 15, Sub. B -

Unintentional Radiators. ICES-003 is the same as FCC Part 15 Sub. B and Industry Canada accepts FCC test report or CISPR 22 test report for compliance with ICES-003. 2020 SmartSense by Digi.
