Using your TRT IP19 LED Digital Display is a breeze. First, connect it to a power source according to the specified power requirements (AC 240/100 +/-10%). You can control the display via your smartphone or computer using USB or Wi - Fi. Just install the appropriate app or software and pair it with the display. For content input, use the HDMI, LAN, or USB ports. When installing, choose the configuration that suits your space, either as a single display or in a multi - screen cascade. Be careful when handling the display to avoid physical damage. Keep it in a clean environment, away from dust and moisture. The operating temperature range is - 10C to +40C, so don't expose it to extreme temperatures. Regularly check the cables for any signs of wear and tear. For long - term use, it's recommended to turn off the display when not in use to save power and extend its lifespan.
