The USB ports are identified by a USB icon. Each USB host port supports 0.5 A
at 5V DC. Connected USB devices must not exceed this power load.
Hi-speed USB 2.0 certified cables are recommended for error-free transmissions.
Connect only externally-powered USB hubs to the terminal. Before attaching
devices to a USB hub, make sure the power adapter is connected and powered on.
