SMART RADAR RETINA-4FN Imaging Radar User Manual
Overview
General Description
The RETINA (Radar Enabled True Imaging by Neural Analysis)-4FN is 4D (X, Y, Z, Velocity) Imaging Radar implements automotive and industrial grade requirements for solution application allowing to precisely collect the distance and velocity information of target objects not only horizontally, but also vertically with single module. RETINA-4FN beams radio-electric waves and analyzes the reflected waves to detect objects in front and to get the 4D information of the objects. The radio-electric wave works well even in the bad environmental challenges, such as fog, smoke, rain, snow, night, flare, and dust. Detection that involves any moving objects such as car, drone, robot, airplane, ship and/or boat. Needs to factor in the surrounding environment precisely under any challenging circumstances in order to gather most valid result of detection. The RETINA-4FN by Smart Radar System is the ideal solution for various use cases to supplement any existing sensors or other unrecognized applications. RETINA-4FN utilizes 4 multi-chip system to distinguish objects.

Notice
FCC
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.
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:
- Reorient or relocate the receiving antenna
- Increase the separation between the equipment and receiver
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected
- Consult the dealer or an experienced radio/TV technician for help
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
This device should be installed and operated with minimum 20 cm between the radiator and your body.
