Dismount - Before disconnecting USB devices from the LinkStation, they should be dismounted.
Hold the function button down until the function LED glows blue, and then turns off. It's now
safe to unplug your USB device.
Note: Unplugging USB devices without dismounting them first may corrupt your data!
Initialization - You can easily bring your LinkStation back to

will shut down after about 90 seconds.
2. While holding down the function button, move the power
switch to the 'On' postion. The function LED on the front of the
