To use this Crestron touch screen, first make sure it's properly connected to the power source. When you start using it, if you encounter a problem where you can't do a factory reset because the login blocks the Setup menu, try checking your login details or contact the Crestron support team. For maintenance, keep the screen clean with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials on the screen. Also, try to keep it in a stable environment with a proper temperature and humidity level to ensure its long - term performance.
