Operating System
• Windows® 8 or 10

Operating Temperature
Due to the high performance of Thunderbolt technology,
Thunderbolt products sometimes generate more heat than
traditional hardware. Therefore, it’s normal for the docking
station to warm up when in use. As such, it’s recommended that
you don’t place your laptop on the docking station’s surface, as
doing so will result in even higher temperatures.
These higher temperatures do not present a safety hazard to
users or to hardware.
Installation
Powering the Docking Station
1. Select the appropriate regional Power Cord and connect it
to the Universal Power Adapter.
2. Connect the Universal Power Adapter to the DC 20V Port
on the Docking Station and to an AC Electrical Outlet.
