The UD-7400PD has a power button located on the front of the unit. When the unit is connected to an electrical power source, the dock will power on automatically.

The unit can be manually powered off by pressing the power button once. After the unit is manually powered off, it can be manually powered back on by pressing the power button once.

Please note, the power button only controls the power status of the docking station unit. It does NOT control the power status of the connected host computer.
