Application This Specification is applied to ATEC IOT Wireless Electronic Shelf Label. (REBE-TZ29C) REBE-TZ29C is used by retailers for displaying product pricing on shelves. Typically, electronic display modules are attached to the front edge of retail shelving. These modules use Electrophoretic Display (EPD) or similar screen technologies to show the current product price to the customer. A communication network allows the price display to be automatically updated whenever a product price is changed. 2. Quality Quality should meet each condition which mentioned on this specification. However, the items which are not mentioned on this specification follow the inspection agreements and standards which are agree with both companies. 3. Appearance and Characteristics Appearance should not be contaminated by harmful materials and should not have cracks, etc. Mechanical dimensions should meet the contents of clause 9. 3.1. Appearance Electrical Characteristics should meet the contents of clause 7. 3.2. Characteristic 4 / 21 4.
