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 Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment .This equipment should be installed and operated with minimum distance 20cm between the radiator& your body. 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 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. SUNMI Technology Page 4/16 1 Preliminary Work Before implementing a formal deployment, the following preparations need to be completed: 1. Business cooperation process; 2. Statistics on the number and type of store ESLs; 3. Statistics on the installation mode of store ESLs (the type and quantity of guide rails and clamps); 4. Location determination of the access point installation (focus on the network wiring); 5. Cloud deployment mode confirmation (SaaS or private cloud). For the specific preparation process, please see implementation preparation collected in the separate project documentation. 2 Product docking It is necessary to start the docking of product information as soon as possible, after the confirmation of business contract and the confirmation of product docking demand. It takes about two weeks for product information docking. The general process of product information docking is as follows: 1. SUNMI, the software partner shall discuss docking requirements and release technical documents; 2. Confirm the docking plan and schedule the project; 3. Developing docking interface and launching after multiple environmen…
