Precautions “This RF device operates on the 2.4GHz and Sub-GHz frequency band and can produce radio interference. The device, therefore, may not be used for applications where safety of human lives is concerned.” 1) Usage Environment Take extra caution when using this RF device in the vicinity of other electronic devices and appliances. Most electronic devices and appliances use electromagnetic waves. Electromagnetic waves emitted by this RF device can affect other electronic devices and appliances. If using the device in an explosion hazard area, follow all safety regulations, instructions, and signals. 2) Storage and Use Moisture and liquids can damage internal parts and circuit boards if allowed to enter into the device itself. Do not place or store the product on a sloped surface. The product may slide and fall off the surface and damage. Use the product in temperatures ranging from -25°C to +60°C. Parts and circuits may damage if used or stored under temperature extremes. Avoid areas with strong magnetism or subject to magnetism. Contact between the device and a magnetic object can lead to malfunctions. Do not place the product near heat-producing kitchen appliances like a stove or a microwave or in the vicinity of highly pressurized containers. External impact to the product, such as from being dropped, can damage the screen. Twisting and bending the product can damage the exterior casing and the internal components. 6 2. Overview Gateway make up a system the electronically displays price and other product information that are traditionally shown printed or written on paper in places like the supermarket. Here, ESL(Electronic Shelf Label) Gateway receives product price updates from the server and uploads the new data to the applicable electronic shelf label tags (ESL-Tag), changing the displayed price information. <Diagram 1> ESL System 7 3.
