2.3. Onboard Antenna
The UNI42 Radar module has built-in microstrip patch antennas for both transmitters and
receivers. The antennas are connected directly to the Radar transceiver chip via microstrip
transmission lines, and the connections are permanent. Per FCC regulation, the end user is
prohibited from modifying any part of the antennas and the feed traces.
3. System Integration Considerations
3.1. Hardware
Brief/general discussion on how end user could integrate this module with a host system, from HW
perspective.
3.2. Software
The module is configured by the host through commands sent over the UART port. Please consult
with the module manufacturer for details.
3.3. Test Modes
When the UNI42 Radar module is installed in a host, the host manufacturer may need to disable the
module in order to perform certain tests such as FCC Part 15 Subpart B.
In order to disable the transmitter, the following command should be issued to the module over the
UART port:
sensorStop
To return the transmitter to its normal operating state, the following command should be issued to
the module over the UART port:
sensorStart
QA-FR-175-A
4. Regulatory Compliance
4.1. Operational Considerations
TheUNI42 Radar module is designed to transmit at power level that meets the FCC EIRP peak
power requirement. The host manufacturer does not have the ability to adjust the output power.
4.2. RF Exposure Considerations
In accordance to the EN 62311 RF exposure test on the Radar transceiver, a minimum separation
distance of 20 centimeters should be maintained between the user and the UNI42 Radar module
during operation.
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. End users must follow the specific operating instructions for satisfying RF exposure
compliance. This transmitter must be at least 20 cm from the user and must not be co-located or
operating in conjunction with any other antenna or transmitter. The information in this guide may
change without notice. The manufacturer assumes no responsibility for any errors that may appear
in this guide
This equipment complies with the IC RSS-102 radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated with a minimum
distance of 20 cm between the radiator and your body.
Énoncé d'exposition aux rayonnements: Cet équipement est conforme aux limites d'exposition aux
rayonnements ioniques RSS-102 Pour un environnement incontrôlé. Cet équipement doit être
installé et utilisé avec un Distance minimale de 20 cm entre le radiateur et votre corps.
4.3. Label and Compliance Information
The UNI42 Radar module is shipped with FCC/IC ID label permanently affixed to its RF shield.
The label is shown below:
Figure 3: FCC/IC Label
4.4. Part 15 Subpart B Disclaimer
The UNI42 Radar module is only authorized for FCC Part 15.255 and IC RSS-210 rules
(intentional transmitter). While this module is also FCC Part 15b and/or IC ES-003 compliant
(unintentional radiator), the end user must ensure the final host product still meets Part 15b and/or
QA-FR-175-A
IC ES-003 compliance through testing with the UNI42 module installed.
4.5. FCC Statements
per 47 CFR §15.105 Class B Device
Note: 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 when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference to
radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.
per 47 CFR §15.19
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.
per 47 CFR §15.21
The user’s manual or instruction manual for an intentional or unintentional radiator shall caution
the user that changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment. In cases where the manual is
provided only in a form other than paper, such as on a computer disk or over the Internet, the
information required by this section may be included in the manual in that alternative form,
provided the user can reasonably be expected to have the capability to access information in that
form.
4.6. ISED Statements
This device complies with Innovation, Science and Economic Development Canada’s license-
exempt RSSs. 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.
Cet appareil est conforme aux flux RSS exemptés de licence d'Innovation, Science et
Développement économique Canada. L'opération est soumise aux deux conditions suivantes:
(1) Cet appareil ne doit pas provoquer d'interférence; et
(2) Cet appareil doit accepter toute interférence, y compris les interférences susceptibles de
provoquer un fonctionnement indésirable de l'appareil.
QA-FR-175-A
OEM Warnings
The modular transmitter must be equipped with either a permanently affixed label or must be
capable of electronically displaying its FCC/ISED identification number:
(A) If using a permanently affixed label, the modular transmitter must be labeled with its own
FCC/ISED identification number, and, if the FCC identification number is not visible when the
module is installed inside another device, then the outside of the device into which the module is
installed must also display a label referring to the enclosed module. This exterior label can use
wording such as the following: “Contains Transmitter Module FCC ID: 2AXUT-UNI42; IC:
26578-UNI42.” Any similar wording that expresses the same meaning may be used. The Grantee
may either provide such a label, an example of which must be included in the application for
equipment authorization, or, must provide adequate instructions along with the module which
explain this requirement. In the latter case, a copy of these instructions must be included in the
application for equipment authorization.
L'émetteur modulaire doit être équipé d'une étiquette apposée en permanence ou doit être capable
d'afficher électroniquement son numéro d'identification FCC / ISED:
(A) Si vous utilisez une étiquette fixée en permanence, le transmetteur modulaire doit être étiqueté
avec son propre numéro d'identification FCC / ISED, et, si le numéro d'identification FCC n'est pas
visible lorsque le module est installé à l'intérieur d'un autre appareil, alors l'extérieur de l'appareil
dans lequel le module est installé doit également afficher une étiquette faisant référence au module
inclus. Cette étiquette extérieure peut utiliser un libellé tel que le suivant: «Contient un module
émetteur FCC ID: 2AXUT-UNI42; IC: 26578-UNI42. " Toute formulation similaire qui exprime
le même sens peut être utilisée. Le bénéficiaire peut soit fournir une telle étiquette, dont un
exemple doit être inclus dans la demande d'autorisation d'équipement, soit fournir des instructions
adéquates avec le module expliquant cette exigence. Dans ce dernier cas, une copie de ces
instructions doit être jointe à la demande d'autorisation d'équipement.
