2BU9I-ET0154Electronic Shelf Label

Third-Generation Four-Color Price Tag User Manual Overview The price tag is installed on a dedicated guide rail. With the eRetail 3.2 system and base stations such as ETAP05, the price tag can communicate with the base station to update screen display content and enable light-flashing functions. It can also be used with a mobile phone via NFC, allowing NFC-based control of page refresh and light flashing through the mobile app. Includes Size Model Image 1.54 ET0154-80 Equipment One ETAP05 base station, several third-generation four-color price tags, and one price tag guide rail. Operating Procedure 1 Device Installation （1） The price tag can be installed directly on the shelf guide rail, or used together with price tag accessories such as brackets, clamps, hooks, and bases. （2） When installing on the guide rail, align the snap-fit structure on the back of the price tag with the rail slot, then slide or press it into place, and adjust it to the corresponding product position. （3） When used with accessories, select suitable accessories according to the actual scenario, and complete installation by snap-fitting, clamping, hanging, or fixing. （4） After installation, make sure the price tag is securely fixed, the display direction is correct, the screen is not blocked, and the price tag ID corresponds to the product information. Base Station Installation 2 System Procedure （1） Enter the base station configuration backend to configure the base station, and configure it to the corresponding server. （2） Open the deployed eRetail 3.2 computer backend, and batch-add the price tags to be used into the backend. （3） Use the test tool or mobile app to bind products and push data. （4） The price tag receives data normally and displays the bound product image. FCC STATEMENT 1. 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. 2. Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. 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. FCC Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, Human proximity to the antenna shall not be less than 20cm(8 inches)during normal operation.
