THE KINEXON SafeZone Tag 
KINEXON SafeZone
The smart wearable ensures physical distancing
| The KINEXON SafeTag is the heart of the KINEXON SafeZone solution. KINEXON SafeZone is a data protection-compliant solution for companies to ensure physical distancing of employees in times of COVID-19 and trace contact chains in case of an infection. The sensors measure the distance and contact duration between the workers with the highest precision (10 cm) at a rate of approx. once per second. The measurement takes place in real-time. If the minimum distance between two employees is compromised for an extended period of time (customizable) the sensors will emit a light signal and an audible warning tone. Wearing options for employees:
| Use Cases Distance control and tracing of contact chains:
KINEXON SafeZone can be used both indoors and outdoors. |

5.4 FCC Compliance
This device complies with 47 CFR 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. The user is cautioned that changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. This device may not be employed for the operation of toys. Operation on board an aircraft, a ship or a satellite is prohibited. The use of this device mounted on outdoor structures, e.g., on the outside of a building or on a telephone pole, or any fixed outdoor infrastructure is prohibited. Moreover, the following statements apply:
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 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 to 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 is designed not to exceed the limits for exposure to radio waves adopted by the FCC. These limits include a substantial safety margin design to assure the safety of all persons, regardless of age and health. The radio wave exposure guidelines use a unit of measurement known as the Specific Absorption Rate (SAR). SAR levels have been computed for the transmitters in this device and have been found to be below FCC limits.
5.6 ISED Caution
