Restore button
There is a button hidden in the box for restoring the system factory default settings. When the system fails
to install or operates abnormally, use the included assistant stick in the package and follow the following
procedures to reset the system back to its original status.
Poke the assistant stick into the hole to press down on the restore button. Restart the system by
unplugging and re-plugging the power jack. While keeping the button pressed, the system will perform
POST twice rather than the usual once, which can be observed from the flashing LEDs. After the system
flashes the LEDs for the second time, withdraw the stick to release the button. The system will have
restored factory default settings at that moment.
Power adapter
Connect the power jack of the included power adapter. Connecting the power adapter should be the last
operation while physically installing NetworKam.
