> This device complies with part 95 subpart M.

> 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 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:

connected. 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

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 Prohibited applications of radar equipment under this service rule include fixed radar use outside of airport areas and airborne radar operations. body.

> A bracket is an auxiliary device and fixed the radar with screw.

> The cable image is as above, and the connector pin map is the table as below. Prepare the HDMS FMCW Radar Test kit in a few steps :

[Figure 2-1. Radar and bracket assembly]

First, connect the radar and the bracket, then tighten the four screws in each position as Figure 2-1 shown.

> After fixing the radar on the bracket, fix the bracket to the desired position to use the radar sensor.

[Figure 2-2. Radar connector and cable assembly]

[Figure 2-3. After finished connect radar and cable]

> Connect each connector in the correct direction. (If the direction is wrong, the connection will not work.)

> The connector pin map is shown in Figure 1.3 and the power supply and CAN cable must be connected.

> According to the contents of 1.3, connect power (12/24 V), GND and CAN H / L to check whether normal operation is possible.

> The radar should be mounted 1.5 m from the ground, and the angle of inclination should be tilted upward about 5 to 10 degrees. occurred while moving.

If you installed it with 0 degree reference, it should be necessarily checked because ground effects may be

> Put on the iron bar and attach it 1.5 m from the ground.

> After mounting test, measure at wide open space.

> The preference angle of the radar is upward 5 ~ 10 degree

> There is a misrecognition possibility if the environment is complicated

> For wheel loader, mounting position is 1.5 m from the ground

In the case of excavators, mounting position is 1.5 m from the ground.

> The test area is a wide open space (about 10 m behind the object should not be exist)

For moving tests, it is also recommended to test in wide empty space.

> Moving test requires additional function to remove ground effect.
