Overview
General Description
The RM68-SE Module from Smart Radar System (SRS) is optimized to detect vehicles on the road and distinguish lanes within a distance of 80m. It has an embedded program on the board that can be configured to meet the various application requirements. It uses TI’s integrated single-chip mmWave sensor IWR6843, to support a friendly and easy-to-use FMCW (Frequency Modulated Continuous Wave) radar platform. Unique antenna design technology and algorithms by SRS have enabled the detection of various objects and reliable performance.
Additionally, the TI device includes two ARM R4F-based processor subsystems: one processor subsystem is for master control, and additional algorithms; a second processor subsystem is responsible for front-end configuration, control, and calibration. It can be configured to respond to a variety of application needs by simple programming.

Notice for FCC/IC
FCC Approval
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 Caution : Any changes or modifications not expressly approved by the
party responsible for compliance could void the user’s authority to operate
this equipment.
This device should be installed and operated with minimum 20Cm between the
radiator and your body.
IC Approval
This device contains license-exempt transmitter(s)/receiver that comply with
Innovation, Science and Economic Development Canada’s license-exempt RSS(s).
Operation is subject to the following two conditions:(1) This device may not
cause interference. (2) This device must accept any interference, including
interference that may cause undesired operation of the device.
This equipment should be installed and operated with minimum 20 cm between the radiator and your body.
INTEGRATION INSTRUCTIONS
List of applicable FCC/ISED rules
This module complies with Part 15.255 of the FCC rule.
This module complies with RSS-210 of ISED rule.
Summarize the specific operational use conditions
15.255(a) Operation under the provisions of this section is not permitted for
the following products:
(1) Equipment used on satellites.
(2) Field disturbance sensors, including vehicle radar systems, unless
the field disturbance sensors are employed for fixed operation, or used as
short-range devices for interactive motion sensing. For the purposes of this
section, the reference to fixed operation includes field disturbance sensors
installed in fixed equipment, even if the sensor itself moves within the
equipment.
Per RSS-210 Annex J, the following devices are not permitted:
(a) devices used on satellites
(b) field disturbance sensors, including vehicle radar systems, unless
the field disturbance sensors are employed for fixed operation or used as
short-range devices for interactive motion sensing (for the purposes of this
section, reference to fixed operation includes field disturbance sensors
installed in fixed equipment, even if the sensor itself moves within the
equipment)
The module is limited to installation in fixed applications only.

RF exposure considerations
This module complies with FCC RF radiation exposure limits set forth for an
uncontrolled environment.
This device should be installed and operated with minimum 20Cm between the
radiator and your body. The host manual shall include the RF exposure
statements. If RF exposure statements and use conditions are not provided,
then the host product manufacturer is required to take responsibility of the
module through a change in FCC ID (new application).
Antennas
The module itself has antenna.
Label and compliance information
The module is labeled with its own FCC/IC. If the FCC ID/IC 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. In that case, the final end product must be labeled in
a visible area with the following;
For FCC: “Contains FCC ID: 2AVKZRM68-SE”
For ISED: “Contains IC: 26970-RM68SE”
The host manual shall include the following regulatory statement:
For FCC:

Information on test modes and additional testing requirements
Testing of the host product with all the transmitters installed – referred to
as the composite investigation test- is recommended, to verify that the host
product meets all the applicable FCC rules. The host manufacturer can use the
software to control the RF signal during test. For more information, please
contact us.
Additional testing, Part 15 Subpart B disclaimer
The modular transmitter is only FCC authorized for the specific rule parts
(i.e., FCC transmitter rules) listed on the grant, and that the host product
manufacturer is responsible for compliance to any other FCC rules that apply
to the host not covered by the modular transmitter grant of certification.
The host product may need to be evaluated against the FCC Part 15B criteria
for unintentional radiators in order to be properly authorized for operation
as a Part 15 digital device.
